ABSTRACT

Abstract This study assessed the anthelminthic feed additive albendazole effect on the main indicators of the quality of sheep meat obtained from infected and deworming animals. A total of 20 heads of Akzhaik meat and wool sheep (i.e. 2 years of age, of different sex) were used in a 20-day experiment and 2 groups of 10 heads were formed (n = 4). The sheep were fed with the basic diet (i.e. control, group CON), without adding anything, and the second group was fed the basic diet orally with the addition of a dose of 1.2 g / head (an experimental group). At the end of the experiment, a control slaughter was carried out from each group in order to study the biochemical composition of meat and its quality. The anthelmintic feed additive albendazole did not have a significant effect on the indicators (organoleptic and physicochemical) of meat quality (P> 0.04). However, the ratio of fat and ash in the meat of the control group has differences in indicators and is reduced by 24.81% and 0.03%, respectively. The drug had a significant effect on the biological value of meat in the experimental group, where there is a higher content of essential amino acids (P = 0.06), nonessential (P = 0.05) concentrations in comparison with the CON groups. The results obtained show that the meat of the experimental groups of sheep, when using the anthelminthic feed additive albendazole, did not have a significant effect on organoleptic parameters, but significantly positively influenced the metabolism, live weight gain and biological value of meat.


Resumo Este estudo avaliou o efeito do aditivo anti-helmíntico albendazol sobre os principais indicadores de qualidade da carne ovina obtida de animais infectados e desparasitados. Um total de 20 cabeças de carne Akzhaik e ovelhas de lã (ou seja, 2 anos de idade, de sexo diferente) foi usado em um experimento de 20 dias e dois grupos de 10 cabeças foram formados (n = 4). As ovelhas foram alimentadas com dieta básica (ou seja, controle, grupo CON), sem adicionar nada, e o segundo grupo foi alimentado com dieta básica por via oral com a adição de uma dose de 1,2 g / cabeça (um grupo experimental). Ao final do experimento, foi realizado um abate controle de cada grupo para estudar a composição bioquímica da carne e sua qualidade. O aditivo anti-helmíntico albendazol não teve efeito significativo sobre os indicadores (organolépticos e físico-químicos) de qualidade da carne (P > 0,04). No entanto, a proporção de gordura e cinzas na carne do grupo de controle tem diferenças nos indicadores e é reduzida em 24,81% e 0,03%, respectivamente. A droga teve efeito significativo sobre o valor biológico da carne no grupo experimental, onde há maior teor de aminoácidos essenciais (P = 0,06), concentrações não essenciais (P = 0,05) em comparação com os grupos CON. Os resultados obtidos mostram que a carne dos grupos experimentais de ovinos, ao utilizar o aditivo anti-helmíntico albendazol, não teve efeito significativo nos parâmetros organolépticos, mas influenciou positivamente de forma significativa no metabolismo, ganho de peso vivo e valor biológico da carne.

ABSTRACT

Adulteration in meat products is a widespread issue that could lead to serious threats to public health and religious violations. Technology that offers rapid, sensitive, accurate and reliable detection of meat species is the key to an effectual monitoring and control against meat adulteration. In recent years, high-throughput sequencing-based DNA metabarcoding technology has developed rapidly. With the characteristics of being high-throughput, highly precise and high-speed, this technology can simultaneously identify multiple species in complex samples, thus offering pronounced advantages in the surveillance of adulteration in meat and meat products. Starting with an introduction of the major developments in the high-throughput sequencing technology in the past two decades, this review provides an overview of the technical characteristics and research methods of DNA metabarcoding, summarizes the application of DNA metabarcoding technology in meat adulteration detection over the last few years, discusses the challenges of using DNA metabarcoding technology in the detection of meat adulteration, and provides future prospects on the development of this technology.

ABSTRACT

RESUMEN Objetivo. Estudiar la calidad de la canal y la carne en pollos de ceba que consumen harina de frutos de Roystonea regia (palmiche). Materiales y métodos. Se utilizaron 40 pollos de ceba distribuidos según diseño completamente aleatorizado en cuatro tratamientos: control (maíz-pasta de soya) y la inclusión de 5, 10 y 15% de harina de palmiche. Se estudió el rendimiento de la canal, grasa abdominal y la calidad de la carne (tecnológicos y composición de ácidos grasos). Para los parámetros de apariencia se realizó análisis de varianza no paramétrico de clasificación simple. Resultados. No se encontraron diferencias entre tratamientos para el peso de la canal y pH a los 45 minutos y 24 horas postmortem. Hubo reducción de la grasa abdominal con 5 y 15 % respecto al control (13.00 y 11.96 vs 17.02 g/kg), en tanto que el 10% no difirió del resto (15.10 g/kg) (p<0.01). No se encontraron diferencias en el color, excepto para la luminosidad en el muslo que fue superior con la inclusión de 10 y 15% (48.62 y 49.22) respecto al 5% (45.32) y el control no difirió entre tratamientos (47.53) (p<0.05). La composición de ácidos grasos en las diferentes porciones comestibles mostró que las aves depositaron los ácidos oleico, linoleico y palmítico en mayor concentración. Conclusiones. La inclusión hasta el 15 % de harina de palmiche a las dietas de pollos de ceba no modifica el rendimiento de la canal, reduce la grasa abdominal e incide positivamente en los indicadores de calidad de la carne.


ABSTRACT Objective. To study meat and carcass quality in broilers fed Roystonea regia (royal palm nut) fruits meals. Materials and methods. A total of 40 broilers distributed according to a completely randomized design were used in four treatments: control (corn-soybean paste) and the inclusion of 5, 10 and 15 % royal palm nut meal. The carcass yield, abdominal fat and meat quality (technological and fatty acid composition (FA)) were studied. For the appearance parameters, a non-parametric analysis of simple classification was performed. Results. There were no differences between treatments for carcass weight and pH at 45 minutes and 24 hours postmortem. There was a reduction in abdominal fat by 5 and 15 % compared to the control (13.00 and 11.96 vs. 17.02 g / kg), while 10 % did not differ from the rest (15.10 g/kg) (p<0.01). There were no differences in color, except for the luminosity in the drumstick that was superior with the inclusion of 10 and 15 % (48.62 and 49.22) with respect to 5 % (45.32) and the control did not differ between treatments (47.53) (p<0.05). The composition of FA in the different edible portions showed that the broilers deposited oleic, linoleic and palmitic acids in higher proportions. Conclusions. The inclusion of royal palm nut meal in broiler diets does not change the carcass yield, reduces abdominal fat and positively affects meat quality indicators.

ABSTRACT

Objetivou-se avaliar o efeito da suplementação de cromo-metionina em dietas para frangos de corte criados em estresse por calor, no período de 22 a 43 dias de idade, nos parâmetros de qualidade da carne. Foram utilizados 336 frangos de corte, machos, da linhagem Cobb 500, com 21 dias de idade, distribuídos em delineamento em blocos inteiramente ao acaso, com quatro blocos (cada câmara climática), seis tratamentos (0; 0,10; 0,20; 0,40; 0,80 e 1,20mgkg-1 de Cr na forma de Cr-metionina), oito repetições e sete aves por unidade experimental. Aos 43 dias de idade, duas aves por unidade experimental foram selecionadas e abatidas para avaliação da qualidade da carne de peito, por meio dos parâmetros de pH15min, pH24h, luminosidade (L*), teor de vermelho (a*), teor de amarelo (b*), croma (C*), ângulo hue (Hº), capacidade de retenção de água, perda de peso por cozimento e força de cisalhamento. Houve efeito quadrático (P=0,0070) na capacidade de retenção de água da carne de peito. A suplementação de CrMet não afetou (P>0,05) os demais parâmetros de qualidade da carne. Assim, recomenda-se a suplementação de 0,59mgkg-1 de CrMet para frangos de corte para melhoria da capacidade de retenção de água do peito.(AU)

ABSTRACT

Objetivou-se avaliar a influência da suplementação com minerais biocomplexados sobre a qualidade da carne de frangos da linhagem Label Rouge, de ambos os sexos, criados em sistema alternativo. O delineamento experimental foi inteiramente ao acaso (DIC), disposto em esquema fatorial (3x2), sendo três dietas (controle; 0,50ppm de selênio; 0,40ppm de cromo) e dois sexos. Para a estabilidade lipídica, foi utilizado o DIC, disposto em esquema fatorial (3x2x2), sendo três dietas, dois sexos e dois tempos de armazenamento (zero e 12 meses). Os parâmetros avaliados no peito e na coxa foram: pH final, cor (L* - luminosidade, a* - índice de vermelho, b* - índice de amarelo, C* - índice de saturação e h* - ângulo de tonalidade), perda de peso por cozimento (PPC), força de cisalhamento (FC) e estabilidade lipídica. Além disso, foram avaliadas a proporção das formas químicas da mioglobina da coxa e a quantificação do conteúdo de selênio no peito. Não houve efeito isolado da dieta sobre os parâmetros físicos e químicos do peito e da coxa e sobre a concentração de selênio no peito. As fêmeas apresentaram médias superiores de L* (57,57), b* (10,55) e C* (10,60) do peito; e os machos de L* (55,09) da coxa. Entre os machos, as aves alimentadas com a dieta controle e com cromo expressaram valores superiores de FC da coxa em relação às suplementadas com selênio; para o tratamento com cromo, os machos apresentaram média superior de FC da coxa e, em contrapartida, para o tratamento com selênio, as fêmeas manifestaram a maior média. As amostras submetidas ao período de 12 meses de armazenamento mostraram maiores valores de substâncias reativas ao ácido tiobarbitúrico (TBARS) em ambos os cortes. A suplementação com cromo e selênio biocomplexados não provocou alterações na qualidade da carne; as fêmeas demonstraram melhores atributos de qualidade da carne.(AU)


The objective of the present study was to evaluate the influence of the supplementation with biocomplexed minerals on the quality of the meat of label Rouge lineage chicken, of both genders, reared in an alternative system. The experimental design was completely randomized (CRD) in a factorial scheme (3x2), with three diets (control; 0.50ppm of selenium; 0.40ppm of chromium) and two genders. For lipid stability, the CRD arranged in a factorial scheme (3x2x2) was used, being three diets, two genders and two storage times (0 and 12 months). The parameters evaluated in the breast and in the thigh were: final pH, color (L* - luminosity, a* - red index, b* - yellow index, C* - saturation index and h* - tonality angle), weight loss per cooking (WLC), shear force (SF) and lipid stability. In addition, we evaluated the proportion of chemical forms of myoglobin of the thigh and the quantification of selenium content in the breast. There was no isolated effect of diet on the physical and chemical parameters of the breast and thigh and selenium concentration in the breast. Females had higher mean values of L* (57.57), b* (10.55) and C* (10.60) of the breast; and males of L* (55.09) of the thigh. Among males, poultry fed with the control diet and chromium showed higher SF values of the thigh than those supplemented with selenium; for the treatment with chromium, the males presented superior average of SF of the thigh and, in contrast, for the treatment with selenium, the females had the highest average. Samples submitted to the period of 12-month of storage showed higher values of substances reactive to thiobarbituric acid (TBARS) in both cuts. Supplementation with biocomplexed chromium and selenium did not cause changes in meat quality; females presented better attributes of meat quality.(AU)

ABSTRACT

Abstract Hoplias malabaricus is a non-migratory fish commonly found in the Mogi Guaçu River basin, mainly feeding on fish, small crustaceans and insects. It forms part of the diet for humans, birds and some mammals. This fish has great nutritional value, with both good quality and good quantities of essential vitamins and amino acids. Regarding parasitic fauna, this fish can host different species of helminths in its gastrointestinal tract. The aim of the present study was to investigate the possible interference of parasitism in the meat yield from H. malabaricus and the centesimal composition. For this purpose, fish specimens were collected from marginal lagoons of the Mogi Guaçu River (Pirassununga, state of São Paulo, Brazil) using hooks and fishing nets. We found that all specimens of H. malabaricus were parasitized by at least one species, including larvae of Contracaecum sp. (Nematoda: Anisakidae). Parasitism did not have any significant influence on centesimal composition, but meat yield was negatively correlated with the abundance of larvae.


Resumo Hoplias malabaricus é um peixe comumente encontrado na bacia do rio Mogi Guaçu. Não realiza migração e alimenta-se de peixes, pequenos crustáceos e insetos. Faz parte da dieta de seres humanos, aves e outros mamíferos piscívoros. Apresenta grande valor nutricional em relação à quantidade e à qualidade de vitaminas e aminoácidos essenciais. Em relação à fauna parasitária, este peixe pode albergar diferentes espécies de helmintos em seu trato gastrointestinal. O presente estudo teve como objetivo verificar a eventual interferência do parasitismo no rendimento e na composição centesimal da carne do pescado de H. malabaricus. Para isso, foram realizadas coletas por um ano, em lagoas marginais do rio Mogi Guaçu, Pirassununga, estado de São Paulo, Brasil, utilizando-se anzol e rede de espera. Como resultado, todos os exemplares de H. malabaricus estavam parasitados por, pelo menos, uma espécie de parasita, prevalecendo larvas de Contracaecum sp. (Nematoda: Anisakidae). O parasitismo não afetou a composição centesimal da carne do peixe, mas foi encontrada uma correlação negativa forte entre o rendimento da carne e o número de larvas de parasitos.

ABSTRACT

Abstract Toxoplasmosis occurs worldwide causing economic losses to the animal production and problems to the public health. The study aimed to detect Toxoplasma gondii and Sarcocystis spp.in 141 meat products from commercial meat cuts of pork, beef, and kibbeh sold in commercial markets from Botucatu, SP, Brazil. Samples were bioassayed in mice to isolate the parasite, and the parasite DNA detected by PCR targeting the 529 base pairs repeat element region (PCR-529-bp). All samples resulted negative on bioassay, whereas PCR positive for 9 (6,38%), distributed as 5/48 beef, 3/49 pork, and 1/44 kibbeh. PCR-positive were investigated for the the parasite genotype using multiplex-, nested-, and RFLP-PCR for 11 markers (SAG1, 5'-3'SAG2, alt.SAG2, SAG3, B-TUB, GRA6, L358, c22-8, c29-6, PK1, Apico). Complete genotype was determined on just one PCR-positive sample that matched MAS, TgCkBr89 and TgCkBr147 isolates already identified. In addition, nested- and RFLP-PCR targeting 18S rRNA was run for all PCR-positive samples and, the products, sequenced and aligned to the GenBank at NCBI website. Four samples showed 100% homology with T. gondii (GenBank #L37415.1), three with Sarcocystis hominis (GenBank #AF006471.1), two Sarcocystis cruzi (GenBank #AF176934.1), and one Sarcocystis hirsuta (GenBank #AF006469.1), indicating the circulation of T. gondii and Sarcocystis spp.


Resumo A toxoplasmose está mundialmente distribuída e causa perdas na produção animal e problemas de saúde pública. Objetivou-se detectar Toxoplasma gondii e Sarcocystis spp. em 141 produtos cárneos de origem suína (49), bovina (48) e de quibe cru (44), comercializados em mercados de Botucatu, SP, Brazil. Realizou-se bioensaio das amostras em camundongos para isolamento do parasita, e detecção do DNA pela reação em cadeia pela polimerase, tendo como alvo a região do elemento repetitivo de 529 pares de bases (PCR-529-bp). Todas as amostras foram negativas ao bioensaio e 9 (6,38%) positivas à PCR, sendo 5/48 bovinas, 3/49 suínas e 1/44 quibe. Determinou-se a genotipagem das amostras positivas pela multiplex-, nested- e RFLP-PCR com 11 marcadores (SAG1, 5'-3'SAG2, alt.SAG2, SAG3, B-TUB, GRA6, L358, c22-8, c29-6, PK1, Apico). Obteve-se genótipo completo em uma amostra, semelhante a outros já identificados (MAS, TgCkBr89 e TgCkBr147). Nested- e RFLP-PCR do gene 18S rRNA das amostras positivas à PCR foram realizadas, e os produtos da nested-PCR, sequenciados e alinhados com dados do GenBank no NCBI. Quatro apresentaram 100% de homologia com T. gondii (L37415.1), duas Sarcocystis hominis (AF006471.1), duas Sarcocystis cruzi (AF176934.1), uma Sarcocystis hirsuta (AF006469.1), indicando a circulação de T. gondii e Sarcocystis spp.

ABSTRACT

BACKGROUND@#Food handlers can play a vital role into reducing foodborne diseases by adopting appropriate food handling and sanitation practices in working plants. This study aimed to assess the factors associated with food safety knowledge and practices among meat handlers who work at butcher shops in Bangladesh.@*METHODS@#A cross-sectional study was conducted among 300 meat handlers from January to March, 2021. Data were collected through in-person interviews using a structured questionnaire. The questionnaire consisted of three parts; socio-demographic characteristics, assessments of food safety knowledge, and food safety practices. A multiple logistic regression model was used to identify the factors associated with food safety knowledge and practices.@*RESULTS@#Only 20% [95% confidence interval, (CI) 15.7-24.7] and 16.3% (95% CI 12.3-20.7) of the respondents demonstrated good levels of food safety knowledge and practices, respectively. The factors associated with good levels of food safety knowledge were: having a higher secondary education [adjusted odds ratio (AOR) = 4.57, 95% CI 1.11-18.76], income above 25,000 BDT/month (AOR = 10.52, 95% CI 3.43-32.26), work experience of > 10 years (AOR = 9.31, 95% CI 1.92-45.09), ≥ 8 h per day of work (AOR = 6.14, 95% CI 2.69-13.10), employed on a daily basis (AOR = 4.05, 95% CI 1.16-14.14), and having food safety training (AOR = 8.98 95% CI 2.16-37.32). Good food safety knowledge (AOR = 5.68, 95% CI 2.33-13.87) and working ≥ 8 h per day (AOR = 8.44, 95% CI 3.11-22.91) were significantly associated with a good level of food safety practice.@*CONCLUSIONS@#Poor knowledge and practices regarding food safety were found among Bangladeshi meat handlers. Findings may help public health professionals and practitioners develop targeted strategies to improve food safety knowledge and practices among this population. Such strategies may include education and sensitization on good food safety practices.

ABSTRACT

In recent years, to solve the increasingly prominent problem of the contradiction between human social development and environmental resources, artificial meat has appeared in public view more and more. Generally speaking, the artificial meat can be divided into vegetable protein meat and cell cultured meat. Among them, vegetable protein meat has gradually begun to be commercialized, and cell cultured meat is cultured with animal cells, which is more similar to the real meat. Based on the analysis of the essence of cell cultured meat, we explore the positive significance of cell cultured meat technology for the meat production industry, consumer groups, and the sustainable development of mankind in the future. From the perspective of bioethics, the research, development and production of cell cultured meat can help ensure the sustainable development of human society, improve animal welfare, reduce resource demand, improve the nutritional function of meat products, and provide new growth points for the development of other industries. In addition, the ethical risks of food safety, technology abuse and technical supervision involved in cell cultured meat production are put forward for deep consideration, hoping to provide reference for the sustainable development of artificial meat industry from the perspective of bioethics.

ABSTRACT

This study evaluated the fatty acid composition and qualitative characteristics of meat from lambs feed in feedlot with increasing levels of canola grain. Meat obtained from 27 lambs fed 0, 8 and 16% inclusion of canola grain were analyzed. There was a reduction in the content of saturated fatty acids (SFA): lauric, heptadecanoic, and stearic; and unsaturated fatty acids (UFA): palmitoleic, oleic, and eicosatrienoic, with the increasing levels of canola grain. There was a linear reduction for the ω3 acid and the ω3: ω6 ratio, while the ω6: ω3 ratio increased. But the values observed for this ratio (ω6: ω3) were lower than 4, which is considered a satisfactory value. There was a slight increase (~2%) for the thrombogenicity index and atherogenicity index with the inclusion of canola grain. There was a reduction in the hypocholesterolemic: hypercholesterolemic ratio, with mean values of 2.09 for the diet with 0% inclusion, and 2.06 for 8 and 16% inclusion of canola. Although the inclusion of canola grain for lambs decreased the content of some UFA, reflecting alterations in the correlated nutritional properties, there is a reduction of SFA. The results for instrumental analysis, proximate composition, and sensory acceptance of the lamb meat were similar among the treatments.(AU)


Objetivou-se avaliar a composição dos ácidos graxos e as características qualitativas da carne de cordeiros terminados com níveis crescentes de canola grão na dieta. Foram estudadas amostras de carne provenientes de 27 cordeiros, confinados por 45 dias e alimentados com 00, 08 e 16% de inclusão de canola grão. Houve efeito para os ácidos graxos saturados (AGS): laurico, heptadecanoico e esteárico; ácidos graxos monoinsaturados (AGMI): palmitoleico e oleico; e ácidos graxos polinsaturados (AGPI): eicosatrienoico. Estes ácidos reduziram à medida que os níveis da canola grão aumentaram. Para os AGMI, houve efeito com maior concentração no músculo dos cordeiros alimentados sem a canola grão (49,80%). Houve uma redução linear para o ácido ω3 e para a relação ω3:ω6, enquanto que a relação ω6:ω3 aumentou. A canola grão influenciou o índice de aterogenicidade, com média de 0,57 para o tratamento com 0% de inclusão e 0,58 para os tratamentos com 8% e 16% de inclusão. Observou-se aumento linear para o índice de trombogenicidade com a inclusão da canola grão, cujas médias foram, respectivamente, 0,16, 0,17 e 0,18 para os tratamentos 0%, 8% e 16% de inclusão. Houve redução para a relação hipocolesterolêmicos-hipercolesterolêmicos, com médias de 2,09 para a dieta com 0% de inclusão, e 2,06 para 8% e 16% de inclusão da canola em grão na dieta. A canola grão não influenciou a análise instrumental, composição centesimal e atributos sensoriais da carne.(AU)

ABSTRACT

The international demand for donkeys has increased sharply in recent years, motivated by China's growing interest in producing ejiao (a traditional medicine made from donkey skin) and, in a smaller proportion, donkey meat. Since the Chinese donkey population dropped by 75.4% in the past 25 years, the country has searched for supply in the international market, mainly in Africa and South America. Aiming to understand the participation of Brazil in this scenario, this paper presents and discusses official data on donkey slaughter and donkey meat and skin exports in Brazil from 2002 to 2019. After the recent news reports of donkey trade-related mistreatment in the Brazilian Northeast, the issue has attracted attention from public authorities, the media, and civil society, but it lacked a quantitative description that could give a tangible dimension to the situation. The interpretation of these data is made with the collaboration of qualitative research methods, emphasizing some aspects of human-animal relations.(AU)


A demanda internacional por jumentos vem aumentando drasticamente nos últimos anos, motivada pelo crescente interesse da China em produzir ejiao (medicamento tradicional feito a partir da pele do animal) e, em menor proporção, carne de jumento. Devido à redução de 75,4% na população de jumentos chineses nos últimos 25 anos, o país tem buscado se abastecer no mercado internacional, principalmente na África e na América do Sul. Com o objetivo de compreender a participação do Brasil neste cenário, este artigo apresenta e discute dados oficiais sobre abate de jumentos e exportação de carne e pele de jumentos no Brasil, de 2002 a 2019. Após a recente divulgação de notícias sobre maus-tratos relacionados ao comércio de jumentos no Nordeste do Brasil, o assunto tem atraído a atenção do poder público, da mídia e da sociedade civil, mas ainda carecia de uma descrição quantitativa que pudesse fornecer uma dimensão tangível à situação. A interpretação desses dados é feita com a colaboração de métodos de pesquisa qualitativa, enfatizando algumas facetas das relações humano-animais.(AU)

ABSTRACT

The consumption of meat and meat products can pose consumers into risk due to the presence of biological hazards that can cause foodborne diseases. Thus, this study aimed to compare the microbiological quality of illegal and inspected salami sold in the state of São Paulo, Brazil. For this purpose, 80 salami samples (40 illegal and 40 inspected) were purchased and their microbiological quality was assessed according to the protocol established by the Brazilian Ministry of Health. All samples were considered as acceptable for consumption according to the Brazilian law. However, the samples of illegal salami were significantly higher contaminated with bacteria belonging to the genus Staphylococcus (p = 0.002) and had a higher trend to be contaminated with total coliforms (p = 0.08) and thermotolerant ones (p = 0.07) compared to inspected salami. Salmonella spp. and coagulase-positive Staphylococcus were not detected. In conclusion, although all samples were considered as safe for consumption, illegal salami had a worse microbiological quality when compared to inspected ones.

ABSTRACT

Pathogenic Yersinia enterocolitica (Y. enterocolitica) is one of the food-borne entero-pathogen responsible for yersiniosis in humans. The purpose of this research was to survey the prevalence, virulence-associated genes, and antimicrobial resistance of Y. enterocolitica isolated from meat and meat product samples in Egypt. Forty-one (5.9%) out of 700- samples of chicken meat, beef, ground beef, and sausage were positive Y. enterocolitica with a high prevalence in chicken meat (12%). Five virulence genes (ail, inv, ystA, ystB, and yadA) were characterized among 41 Y. enterocolitica isolates with variable frequencies. Among the strains tested, the ystB gene was detected with a high percentage (78.1%), followed by inv gene (70.7%), ail gene (14.6%), ystA gene (12.2%), and yadA gene (2.4%). A high resistance rate was estimated to amoxicillin-clavulanic acid (100%), followed by cefazolin (95%), ampicillin (65.9%), and doxycycline (51.2%), whilst a high sensitivity rate was observed to gentamicin and ciprofloxacin (97.6% each). Interestingly, the multidrug resistance was specified in the 70.7% of strains and showing 13 resistance patterns. Based on nucleotide sequence analysis of the 16s rRNA gene, the phylogenetic tree showed the genetic relatedness amongst Y. enterocolitica isolates. These findings highlighted the emergence of virulent and multidrug-resistant pathogenic Y. entrocolitica in retailed meat and meat products in Egypt.


A Yersinia enterocolitica patogênica (Y. enterocolitica) é um dos enteropatógenos de origem alimentar responsáveis pela yersiniose no ser humano. O objetivo desta pesquisa foi avaliar a prevalência, genes associados à virulência e resistência antimicrobiana de Y. enterocolitica isolada de amostras de carne e produtos à base de carne no Egito. Quarenta e um (5,9%) de 700 amostras de carne de frango, carne bovina, moída e linguiça foram Y. enterocolitica positivas, com alta prevalência em carne de frango (12%). Cinco genes de virulência (ail, inv, ystA, ystB e yadA) foram caracterizados entre 41 isolados de Y. enterocolitica com frequências variáveis. Entre as cepas testadas, o gene ystB foi detectado com uma alta porcentagem (78,1%), seguido pelo gene inv (70,7%), ail genes (14,6%), gene ystA (12,2%) e gene yadA (2,4%). Foi estimada uma alta taxa de resistência ao ácido amoxicilina-clavulânico (100%), seguida de cefazolina (95%), ampicilina (65,9%) e doxiciclina (51,2%), enquanto uma alta taxa de sensibilidade foi observada para gentamicina e ciprofloxacina (97,6% cada). Curiosamente, a resistência a múltiplas drogas foi especificada em 70,7% das cepas e mostrando 13 padrões de resistência. Com base na análise da sequência nucleotídica do gene rRNA 16s, a árvore filogenética mostrou a relação genética entre isolados de Y. enterocolitica. Esses achados destacaram o surgimento de Y. entrocolitica patogênica virulenta e multirresistente em carnes e produtos à base de carne no Egito.

ABSTRACT

Resumen El presente estudio tuvo como objetivo principal comparar el consumo de pescado de río entre las ciudades de Rosario y el conglomerado Corrientes y Resistencia (CCR). Se encuestaron un total de 508 adultos, seleccionados por un muestreo no probabilístico por conveniencia. Se indagó acerca del consumo de pescado de río, su frecuencia de consumo, especies más consumidas, lugar de adquisición y formas de preparación más utilizadas, mediante una encuesta dirigida con respuestas semiestructuradas. Los datos se procesaron con Microsoft Excel 2010 y EPI Info7. Los resultados indicaron que más del 78% de los participantes manifestaron consumir pescado, pero el número de quienes expresaron consumir pescado de río fue inferior. Se encontró diferencia significativa entre el porcentaje de participantes que declaró consumir pescado de río entre ambas ciudades estudiadas, con un mayor consumo de pescado de río en el CCR (p<0,05). Sólo el 19% de los habitantes del CCR y el 16% de los rosarinos consumen pescado de río semanalmente. En ambas áreas geográficas, el pescado de río se consume "porque les gusta" o "porque lo consideran saludable"; esta última opinión fue significativamente diferente y más importante en CCR (p<0,0001). Dentro de los motivos de rechazo al consumo, en ambas ciudades se encontró como principales causas la "falta de hábito", porque "no les gusta" o porque "producen olor al cocinar". Se encontraron diferencias significativas (p<0,0001) entre las especies más consumidas: en CCR fueron el surubí (73%), dorado (57%) y pacú (46%). Mientras que, en Rosario, fueron boga (62%), dorado (46%) y sábalo (20%). A pesar de ser el pescado de río un recurso disponible en las ciudades evaluadas, la frecuencia de consumo resultó ser baja. Es importante fomentar el consumo de pescado de río, haciendo más eficiente el aprovechamiento de un recurso local y promoviendo una alimentación variada y saludable en la población.


Abstract The main objective of this study was to compare the consumption of river fish between the cities of Rosario and Corrientes and Resistencia conglomerate (CRC). A total of 508 adults were surveyed, selected by non-probability convenience sampling. The consumption of river fish, its frequency of consumption, the most consumed species, the place of acquisition and the most used forms of preparation were investigated through a directed survey with semi-structured responses. The data was processed via Microsoft Excel 2010 and EPI Info7. Results indicated that more than 78% of the participants stated that they consumed fish; but the number of those who consumed river fish was lower. A significant difference was found between the percentage of participants who declared consuming river fish between both cities studied, with a higher consumption in the CRC (p <0.05). Only 19% of the inhabitants of the CRC and 16% of Rosario's residents consume river fish weekly. In both geographic areas, river fish is consumed because "they like it" or because "they consider it healthy"; this last opinion was significantly different and more important in CRC (p <0.0001). Among the reasons for rejection of consumption, in both cities the main causes were "lack of habit", because "they don't like it" or because "they produce smell when cooking". Significant differences (p <0.0001) were found among the most consumed species: in CRC they were surubí (73%), gold (57%) and pacu (46%), while in Rosario they were boga (62%), gold (46%) and shad (20%). Even though river fish is an available resource in the cities evaluated, the frequency of consumption turned out to be low. It is important to encourage the consumption of river fish, to make a local resource more efficient and promote a varied and healthy diet in the population.

ABSTRACT

Devido à importância médica, veterinária, ambiental e forense do califorídeo Chrysomya putoria (Diptera), foi avaliado o desempenho apresentado por estágios imaturos criados em carne de cavalo. Os espécimes foram colocados em câmaras aclimatizadas reguladas a 30 ºC, 60 ± 10% UR e 14 horas de fotofase. Os estágios larval e pupal concluíram seu desenvolvimento em 4,16 e 4,12 dias, respectivamente. As larvas pós-alimentação e pupas com 24h de idade pesaram, em média, 58,06 e 40,10mg, respectivamente. As taxas de emergência registradas foram de 65% nas condições experimentais propostas. Como os compostos orgânicos voláteis são diferentes na decomposição de um animal para outro, este trabalho e outros realizados com a mesma dieta são os mais apropriados para estimativa de intervalo post mortem envolvendo cavalos.(AU)


Due to medical, veterinary, environmental and forensic importance of the calliphorid Chrysomya putoria (Diptera), the performance presented by immature stages, reared on horse meat, was evaluated. The specimens were placed in acclimatized chambers regulated at 30 ºC, 60 ± 10% RU and 14 hours of photo phase. The larval and pupal stages completed their development in 4, 16 and 4, 12 days, respectively. Post-feeding larvae and aged 24h pupae weight on average 58, 06 and 40, 10 mg, respectively. The emergence rates recorded were 65% under the experimental conditions proposed. As volatile organic compounds are different in the decomposition of one animal to another, this work and others carried out with the same diet are the most appropriate for estimating post-mortem interval involving horses.(AU)

ABSTRACT

The food industry and the frozen fish sector in particular have benefitted greatly from advancements in food processing technologies. This study investigated the effect of adding natural antioxidants such as rosemary and thyme oil to frozen fillets of Nile tilapia (Oreochromis niloticus) in order to preserve their quality for consumers. Fillets were treated with rosemary and thyme at two concentrations (1% and 1.5%) and then were stored at 4°C. Samples were analyzed over 4 days for bacteriological (aerobic plate count, psychotropic count, and coliform count), chemical (determination of pH, thiobarbituric acid reactive substances-TBARS, and total volatile base nitrogen-TVB-N), and sensory quality examination (color, texture, and odor). Significant differences (P<0.05) were observed among different groups in terms of aerobic plate count, psychotropic count, and coliform count during the storage. Moreover, pH, TVB-N, and TBARS mean values in the treated groups were lower than those in the untreated group. The best sensory quality was obtained at the highest concentrations (1.5%) of thyme and rosemary oil.(AU)


A indústria de alimentos e o setor de peixes congelados, em particular, se beneficiaram dos avanços nas tecnologias de processamento de alimentos. Este estudo investigou o efeito da adição de antioxidantes naturais, como óleo de alecrim e tomilho, a filetes congelados de tilápia do Nilo (Oreochromis niloticus), a fim de preservar sua qualidade para os consumidores. Os filés foram tratados com alecrim e tomilho em duas concentrações (1% e 1,5%) e, em seguida, foram armazenados a 4°C. As amostras foram analisadas durante 4 dias para análises bacteriológicas (contagem de placas aeróbicas, psicotrópicas e coliformes), químicas (determinação do pH, substâncias reativas ao ácido tiobarbitúrico-TBARS e nitrogênio base volátil total-TVB-N) e exame da qualidade sensorial (cor, textura e odor). Diferenças significativas (P<0,05) foram observadas entre os diferentes grupos na contagem aeróbia de placas, contagem psicotrópica e contagem de coliformes durante o armazenamento. Além disso, os valores médios de pH, TVB-N e TBARS nos grupos tratados foram inferiores aos do grupo não tratado. A melhor qualidade sensorial foi obtida nas maiores concentrações (1,5%) de tomilho e óleo de alecrim.(AU)

ABSTRACT

The aim of research was to evaluate the meat quality of Nellore young bulls in grazing supplemented with or without addition of lipids. Twenty­four young bulls, 301 ± 5.8 kg in body weight, were used in the experiment and randomly distributed into four groups according to treatment: only Panicum maximum cv. Mombasa grass; Mombasa grass with concentrated supplementation based on soybean meal; Mombasa grass with concentrate containing lipids from soybean oil; and Mombasa grass with concentrate containing lipids derived from soybean grains. There were no differences (P>0.05) between the treatments for temperature, pH, thawing, cooking and total losses, shear force, sarcomere length and collagen in bulls. Nellore young bulls raised in fertilized and irrigated Mombasa grass fed Mombasa grass only or supplemented with or without addition of lipids were similar regarding meat quality.


Objetivou-se com esta pesquisa avaliar a qualidade da carne de novilhos Nelore em pastejo suplementado com ou sem adição de lipídios. Vinte e quatro novilhos, 301 ± 5,8 kg de peso vivo, foram utilizados no experimento e distribuídos aleatoriamente em quatro grupos de acordo com os tratamentos: somente Panicum maximum cv. capim-mombaça; capim-mombaça com suplementação concentrada à base de farelo de soja; capim-mombaça com concentrado contendo lipídios do óleo de soja; e capim-mombaça com concentrado contendo lipídios derivados de grãos de soja. Não houve diferenças (P>0,05) entre os tratamentos para temperatura, pH, perdas por descongelamento, perdas por cozimento e perdas totais, força de cisalhamento, comprimento de sarcômero e colágeno nos touros. Novilhos Nelore criados em capim-mombaça fertilizado e irrigado, alimentados apenas com capim-mombaça ou suplementados com ou sem adição de lipídeos, foram semelhantes quanto à qualidade da carne.

ABSTRACT

Resumen Introducción: debido a la pandemia del coronavirus humano COVID-19, se implementaron estrategias preventivas basadas en el aislamiento social preventivo y obligatorio (cuarentena) para reducir la transmisión en la comunidad, lo cual ha impactado en el estilo de vida y en los hábitos alimentarios. Objetivo: analizar el consumo alimentario durante el período de cuarentena en Argentina. Materiales y método: se desarrolló un estudio observacional, exploratorio, de corte transversal. Se diseñaron dos cuestionarios de encuesta para ser completados en formato online, uno para la población que consume carnes (PC) y otro para la población veg(etari)ana (PV). Se incluyeron preguntas de opción múltiple sobre características sociodemográficas, peso y talla autoreferidos, antecedentes de enfermedades crónicas, ingesta habitual de alimentos y su percepción de modificación durante el período de aislamiento social. A 12 días de decretada la cuarentena, se hizo un primer corte en el relevamiento de datos para realizar un análisis descriptivo. Resultados: la muestra quedó conformada por 2518 personas que contestaron el formulario (2201 PC y 317 PV). Se observó una modificación en los hábitos alimentarios en el período de encierro en ambos grupos, caracterizada principalmente por un descenso en el consumo de alimentos con potencial inmunomodulador como frutas y verduras y un aumento en la ingesta de alimentos desaconsejados como panificados, golosinas, bebidas azucaradas y alcohólicas. Conclusiones: es fundamental considerar el impacto acontecido en el estilo de vida y específicamente en la alimentación, ya que dietas poco saludables podrían aumentar la susceptibilidad a COVID-19 y afectar la recuperación.


Abstract Introduction: due to the pandemic of the human coronavirus COVID-19, preventive strategies based on preventive and mandatory social isolation (quarantine) were implemented to reduce transmission in the community, and this has impacted on lifestyle and eating habits. Objective: to analyze food intake during the quarantine period in Argentina. Materials and Method: an observational, exploratory, cross-sectional study was carried out. Two survey questionnaires were designed to be completed online, one for the meat-consuming population (MP) and the other for the vegan/vegetarian population (VP). Multiple-choice questions on sociodemographic characteristics, self-reported weight and height, history of chronic diseases, habitual food intake and perception of modification during the period of social isolation were included. 12 days after the quarantine was decreed, a first cut was made in the data survey to carry out a descriptive analysis. Results: the sample was made up of 2518 people who answered the form (2201 MP and 317 VP). A change in dietary habits was observed in the period of confinement, in both groups, characterized mainly by a decrease in the consumption of immunomodulatory potential food such as fruits and vegetables, and an increased intake of bakery products, sweets, sugary drinks and alcoholic beverages. Conclusions the quarantine impact due to COVID-19 on lifestyle and specifically on unhealthy diet could increase susceptibility to COVID-19 and affect recovery.

ABSTRACT

Abstract This article aims to identify meat preparation techniques according to sociodemographic variables and health-related behaviors. Cross-sectional population-based survey that used one 24-hour recall to identify the meat preparation techniques. We analyzed 3,376 24-hour recalls. The meat preparation techniques were classified as moist-heat (sauté, stew, boil; MH) or dry-heat (sauté, stew, boil; MH) and dry-heat (baking, grilling/barbecuing and frying; DH). The prevalence of use was 39.0% for moist cooking, 32.7% for frying and 28.3% for baking/grilling. Women, the elderly and those from other municipalities/states were more likely to use MH cooking. MH techniques were least prevalent among those of higher socioeconomic status. Among the techniques of DH cooking, women, the elderly and people with higher education and income were less likely to fry meats. Those born in Campinas and those with higher income, education, and those who ate fruits and vegetables on a higher weekly frequency were more likely to roast/grill meats. The results show the epidemiological profile associated with meat preparation techniques. Women, the elderly and those with lower education are more likely to use MH cooking techniques and less likely to fry meats. Those economically more favored are less likely to use MH techniques and frying, and more roasting/grilling.


Resumo O objetivo deste artigo é identificar as técnicas de preparo utilizadas em carnes, segundo variáveis sociodemográficas e de comportamentos relacionados à saúde. Trata-se de estudo transversal de base populacional que utilizou um Recordatório de 24 horas para identificar as técnicas de preparo de carnes. Foram analisados 3.376 recordatórios. As técnicas de preparo foram classificadas em cocção úmida (refogar, ensopar, fervura) e cocção seca (assar, grelhar, fritar). As prevalências de uso foram de 39,0% para cocção úmida, 32,7% para fritura e 28,3% para assar/grelhar. A cocção úmida foi mais prevalente nas mulheres, idosos e nos naturais de outros municípios/Estados, e menos prevalente nos segmentos de melhor nível socioeconômico. Das técnicas de cocção seca, a fritura foi menos utilizada por mulheres, idosos e por pessoas com maior nível de educação e renda. O assar/grelhar foram as técnicas mais aplicadas pelos nascidos em Campinas e pelos estratos mais altos de renda, escolaridade, e que ingeriam frutas e hortaliças ≥ 4 vezes/semana. Os resultados revelam o perfil epidemiológico associado às técnicas de preparo de carnes; mulheres e idosos empregam mais calor úmido e menos fritura, e os mais favorecidos economicamente usam menos cocção úmida e fritura, e mais o assar/grelhar.
