Microbiological contamination present in enteral tube feeding prepared in hospitals and/or at home: a systematic review.

CONTEXT: The safety of enteral formulas is important to restore and maintain the health of patients. OBJECTIVE: A systematic review of the literature was conducted to assess the microbiological contamination present in enteral tube feeding prepared in hospitals and/or at home. DATA SOURCES: A systematic search was conducted of the Medline, Scopus, BVS, CAPES/MEC, Embase, Science Direct, and SciELO databases and gray literature. DATA EXTRACTION: Eligible studies that analyzed the contamination of enteral formulas manipulated in hospitals and/or at home were selected; a quality assessment tool was used. DATA ANALYSIS: Twenty-three studies evaluated 1099 enteral formulations. Of these, 44.67% of enteral formulas (n = 491) exceeded the acceptable bacterial count. Samples of homemade enteral formulation preparations (86.03%; n = 191) had the highest bacterial counts, followed by mixed preparations (79.72%; n = 59), and commercial formulas (30.01%; n = 241). The number of samples of enteral formulations that exceeded the bacterial count at home was 70.79% (n = 160 at the hospital was 37.91% (n = 331). Total coliforms (82.68%; n = 406) and mesophilic aerobes (79.22%; n = 389) were the most common microorganisms. Samples with bacterial pathogens were also identified, with Bacillus cereus (4.07%; n = 20) and Listeria monocytogenes (3.66%; n = 18) being the most prevalent. CONCLUSIONS: A high number of samples of enteral formulations exceeded the bacterial count, but the risk to patient's health when consuming enteral tube feeding prepared in hospitals or at home may be low. This is because the bacteria present in the samples are not considered potential causes of disease but rather indicators of hygiene conditions.

Development of an Educational Gamification Strategy to Enhance the Food Safety Practices of Family Farmers in Public Food Markets of Northeast Brazil: A Case Study.

This study aimed to develop an educational gamification strategy to enhance the food safety practices of family farmers in public food markets in a city in Northeastern Brazil (João Pessoa, PB, Brazil). A good manufacturing practices (GMP) checklist was used to verify hygienic-sanitary conditions in the food markets. Educational game tools addressing foodborne diseases and GMP with information about the prevention of foodborne diseases, good food handling practices, and safe food storage were developed. Pre- and post-training assessments were done to evaluate food handlers' knowledge and food safety practices. Microbiological parameters of food samples were analyzed before and two months after the training. Results indicated unsatisfactory hygiene conditions in the examined food markets. There was a very strong positive correlation between "implementation of GMP" and "production and process controls" (R = 0.95; p ≤ 0.05) and between "production and process controls" and "hygiene habits of handlers" (R = 0.92; p ≤0.05). There was no homogeneity between answers before and after the training for the knowledge of family farmers regarding "prevention of foodborne diseases" and "safe food handling". There were improvements in the measured microbiological parameters of foods sold by family farmers after the application of the developed educational gamification training. These results showed the developed educational game-based strategy as being effective in raising awareness of hygienic sanitary practices, helping to promote food safety, and reducing risks for the consumers of street foods at family farmers' markets.

Irregularidades registradas durante inspeções sanitárias em restaurantes e similares / Irregularities recorded during sanitary inspections in restaurants and similar

Identificar irregularidades em restaurantes pode auxiliar a minimizar riscos de contaminação. O objetivo desse estudo foi analisar as irregularidades registradas em inspeções sanitárias de restaurantes e similares em Curitiba, Brasil, entre 2005 a 2017. A descrição das irregularidades foi organizada seguindo as categorias e os itens da legislação de Boas Práticas (BP) para serviços de alimentação do Brasil e as cinco chaves para uma alimentação mais segura, definidas pela Organização Mundial da Saúde. Do total de 4.098 registros, houve a descrição de 8.327 irregularidades. Em relação às BP, houve a prevalência da descrição de irregularidades nos anos de 2005, 2006 e 2013, e das categorias: edificações, instalações, equipamentos, móveis e utensílios (42,80%); preparação do alimento (11,54%); documentação e registro (9,92%) e matéria-prima, ingredientes e embalagens (9,06%). Em relação às cinco chaves para uma alimentação mais segura, apenas 3.209 (38,53%) descrições correspondiam a esse tema, com destaque a: manter a limpeza (40,70%) e usar água e matérias-primas seguras (34,71%). Houve uma tendência decrescente na descrição das irregularidades no período estudado, porém ainda é um desafio implementar as BP em restaurantes e similares no Brasil, o que pode favorecer a ocorrência de doenças e aumentar o risco à saúde da população.

Identifying irregularities in restaurants can help minimize contamination risks. The objective of this study was to analyze the irregularities recorded in sanitary inspections of restaurants and similar establishments in Curitiba, Brazil, between 2005 and 2017. The description of the irregularities was categorized following the items and criteria outlined in the Good Practices (GP) legislation for food services of Brazil and the Five Keys to Safer Food, defined by the World Health Organization. Out of the total of 4,098 records, 8,327 irregularities were documented. Concerning GP, there was a prevalence of irregularities described in the years 2005, 2006 and 2013, mainly in the following categories: buildings, installations, equipment, furniture and utensils (42.80%); food preparation (11.54%); documentation and registration (9.92%) and raw materials, ingredients and packaging (9.06%). Regarding the Five Keys to Safer Food, only 3,209 (38.53%) corresponded to this theme, with particular emphasis on maintaining cleanliness (40.70%) and using safe water and raw materials (34.71 %). The study observed a declining trend in the description of irregularities over the study period. However, the successful implementation of GP in restaurants and similar establishments in Brazil remains a challenge, potentially favoring the occurrence of foodborne diseases and increasing the risk to public health.

Comparative evaluation of the effectiveness of alcohol-based sanitizers, UV-C radiation and hot air on three-age Salmonella biofilms.

Dry sanitation is recommended to control contamination and prevent microbial growth and biofilm formation in the low-moisture food manufacturing plants. The objective of this study was to evaluate the effectiveness of dry sanitation protocols on Salmonella three-age biofilms formed on stainless steel (SS) and polypropylene (PP). Biofilms were formed for 24, 48 and 96 h at 37 °C using a cocktail of six Salmonella strains (Muenster, Miami, Glostrup, Javiana, Oranienburg, Yoruba) isolated from the peanut supply chain. Then, the surfaces were exposed to UV-C radiation, hot air (90 °C), 70% ethanol and a commercial product based on isopropyl alcohol for 5, 10, 15 and 30 min. After 30min exposure, on PP the reductions ranged from 3.2 to 4.2 log CFU/cm2 for UV-C, from 2.6 to 3.0 log CFU/cm2 for hot air, from 1.6 to 3.2 log CFU/cm2 for 70% ethanol and from 1.5 to 1.9 log CFU/cm2 for the commercial product. On SS, after the same exposure time, reductions of 1.3-2.2 log CFU/cm2, 2.2 to 3.3 log CFU/cm2, 1.7 to 2.0 log CFU/cm2 and 1.6 to 2.4 log CFU/cm2 were observed for UV-C, hot air, 70% ethanol and commercial product, respectively. UV-C was the only treatment affected by the surface material (p < 0.05) whereas the biofilm age influenced the effectiveness of UV-C and hot air (p < 0.05). For most treatment, there was significant difference among the exposure times (p < 0.05). Overall, the fastest loss in the biofilm viability was noted in the first 5 min, followed by a tail phase. The time predicted by the Weibull model for the first decimal reduction ranged from 0.04 to 9.9 min on PP and from 0.7 to 8.5 min on SS. In addition, the Weibull model indicates that most of treatments (79%) required a long-term exposure time (>30 min) to achieve 3-log reductions of Salmonella biofilms. In summary, UV-C showed the best performance on PP whereas hot air was noted to be the most effective on SS.

Multidrug-Resistant Biofilms (MDR): Main Mechanisms of Tolerance and Resistance in the Food Supply Chain.

Biofilms are mono- or multispecies microbial communities enclosed in an extracellular matrix (EPS). They have high potential for dissemination and are difficult to remove. In addition, biofilms formed by multidrug-resistant strains (MDRs) are even more aggravated if we consider antimicrobial resistance (AMR) as an important public health issue. Quorum sensing (QS) and horizontal gene transfer (HGT) are mechanisms that significantly contribute to the recalcitrance (resistance and tolerance) of biofilms, making them more robust and resistant to conventional sanitation methods. These mechanisms coordinate different strategies involved in AMR, such as activation of a quiescent state of the cells, moderate increase in the expression of the efflux pump, decrease in the membrane potential, antimicrobial inactivation, and modification of the antimicrobial target and the architecture of the EPS matrix itself. There are few studies investigating the impact of the use of inhibitors on the mechanisms of recalcitrance and its impact on the microbiome. Therefore, more studies to elucidate the effect and applications of these methods in the food production chain and the possible combination with antimicrobials to establish new strategies to control MDR biofilms are needed.

Microbial resistance to sanitizers in the food industry: review.

Hygiene programs which comprise the cleaning and sanitization steps are part of the Good Hygiene Practices (GHP) and are considered essential to ensure food safety and quality. Inadequate hygiene practices may contribute to the occurrence of foodborne diseases, development of microbial resistance to sanitizers, and economic losses. In general, the sanitizer resistance is classified as intrinsic or acquired. The former is an inherent characteristic, naturally present in some microorganisms, whereas the latter is linked to genetic modifications that can occur at random or after continuous exposure to a nonnormal condition. The resistance mechanisms can involve changes in membrane permeability or in the efflux pump, and enzymatic activity. The efflux pump mechanism is the most elucidated in relation to the resistance caused by the use of different types of sanitizers. In addition, microbial resistance to sanitizers can also be favored in the presence of biofilms due to the protection given by the glycocalyx matrix and genetic changes. Therefore, this review aimed to show the main microbial resistance mechanisms to sanitizers, including genetic modifications, biofilm formation, and permeability barrier.

Manejo higiénico de los alimentos y enfermedades de transmisión alimentaria / Hygienic handling of food and foodborne diseases

Las enfermedades transmitidas por alimentos (ETA) constituyen un importante problema de salud pública debido a su alta incidencia a nivel mundial, las directrices para la higiene de los alimentos deben ser aplicadas, no solo por la población en general, sino también por los servicios médicos y sistemas hospitalarios. Por tal razón, esta investigación tiene como objetivo conocer las condiciones de higiene de los alimentos y determinar enfermedades de transmisión alimentaria en una clínica de especialidades médicas en la ciudad de Ambato, Ecuador. La investigación fue observacional, descriptivo, de corte transversal, con una muestra de 117 personas de tres turnos de trabajo, a quienes se le aplicó un cuestionario de higiene alimentaria compuesto por 24 ítems distribuido en cinco (5) categorías, el análisis de los datos fue mediante la estadística descriptiva, aplicando el cálculo porcentual y análisis de distribución de frecuencias. Como resultado se evindeció mayor existencia de protocolo/norma para el lavado de manos (76,65%) y menor para la prohibición de uso de joyas y accesorios (29,91%), a pesar de esto, el cumplimiento de protocolo fue 100,00% en equipo de protección personal, prohibición de uso de joyas y accesorios, uso de uñas cortas, limpias y sin esmalte, accidentes cortopunzantes y manejo higiénico de personal con enfermedades dermatológicas, respiratorias y diarreicas. Por otra parte, se encontró un (1) caso de una intoxicación alimentaria causada por una cepa de la bacteria Scherichia coli enterotoxigénica (ETEC) sin identificación de nexo epidemiológico. Concluyendo, la higiene correcta de alimentos podría evitar la propagación de múltiplies enfermedades(AU)

Foodborne illnessare a major public health problem due to their high incidence worldwide, the guidelines for food hygiene must be applied, not only by the general population, but also by medical services and hospital systems. For this reason, this research aims to know the hygiene conditions of food and determine foodborne illness in a medical specialty clinic in the city of Ambato, Ecuador. The research was observational, descriptive, cross-sectional, with a sample of 117 people from three work shifts, to whom a food hygiene questionnaire composed of 24 items distributed in five (5) categories was applied, the data analysis was through descriptive statistics, applying the percentage calculation and frequency distribution analysis. As a result, there was a greater existence of protocol/norm for hand washing (76.65%) and less for the prohibition of the use of jewelry and accessories (29.91%), despite this, compliance with the protocol was 100.00% in personal protection equipment, prohibition of the use of jewelry and accessories, use of short, clean nails without polish, sharps accidents and hygienic handling of personal with dermatological, respiratory and diarrheal diseases. On the other hand, one (1) case of food poisoning caused by a strain of enterotoxigenic Scherichia coli (ETEC) bacteria without identification of an epidemiological link was found. In conclusion, correct food hygiene could prevent the spread of multiple diseases(AU)

Qualidade microbiológica de hortaliças comercializadas em diferentes restaurantes do tipo self-service na cidade do Recife-PE / Microbiological quality of vegetables selled in different self service restaurants in the city of Recife-PE

A falta de tempo para o preparo das refeições, devido ao ritmo de vida acelerado, incentiva a procura por serviços de alimentação fora de casa, em busca de alimentos práticos, de rápido consumo e nutritivos. Com o propósito de fazer uma alimentação mais saudável, cresceu a busca por restaurantes self-service, sendo a salada uma das opções usualmente mais consumida nesses estabelecimentos. Neste contexto, este trabalho teve como objetivo avaliar a qualidade microbiológica de 20 amostras de hortaliças cruas servidas em restaurantes self-service da cidade do Recife-PE. As coletas foram realizadas no mês de fevereiro de 2021. As amostras foram submetidas às análises microbiológicas de coliformes totais, termotolerantes, Escherichia coli e Salmonella spp. Para coliformes totais os resultados variaram entre <3 a >1100 NMP/g. A presença de coliformes termotolerantes foi observada em 16 amostras, destas, uma apresentou contagem acima do estabelecido pela RDC 12/2001 se mostrando imprópria para o consumo. Não foi detectada a presença de Escherichia coli e Salmonella spp. nas amostras analisadas, estando estas de acordo com a RDC 331/2019. Estes resultados sugerem que, como houve a presença de coliformes nas amostras, mesmo estando a maioria dos valores em conformidade, é importante que haja maiores cuidados quanto à higienização e manipulação das hortaliças pelos estabelecimentos. Visando diminuir a carga microbiana presente nesses alimentos, portanto, é necessário que as boas práticas de manipulação sejam adotadas pelos restaurantes, para que se evite o aparecimento de doenças transmitidas por alimentos (DTAs).(AU)

The lack of time to prepare meals, due to a fast-paced contemporary lifestyle, encourages people to seek for alternative food services that are fast, practical, and nutritious. With the purpose of maintaining a healthy diet, the search for self-service restaurants has increased, being salad one of the usual options consumed in these restaurants. In this scenario, the purpose of the study was to investigate the microbiological quality of 20 raw vegetables samples served in restaurants in Recife ­ PE. The tests were carried out in February 2021. The samples were submitted to microbiological analysis of Total Coliform, thermotolerant Coliforms, Escherichia coli and Salmonella spp. For Total Coliform the results ranged from <3 to >1100 MPN/g. The presence of thermotolerant coliforms were observed in 16 samples, and 1 of them had a count above the established for the RDC 12/2001, proving to be unsuitable for consumption. The presence of Escherichia coli and Salmonella spp. were detected in none of the analyzed samples, being in accordance with the RDC 331/2019. These results suggest that, because of the presence of coliforms in the samples, even though most of values are in compliance, it is important to be more careful about hygiene and manipulation of vegetables by restaurants. Therefore, aiming to decrease the microbial load present in these foods, it is necessary that the good handling practices should be adopted in restaurants, to avoid the appearance of foodborne diseases.(AU)

Avaliação das boas práticas na produção de alimentos em escolas públicas do município de Currais Novos, RN / Evaluation of good practices in food production of public schools in Currais Novos, RN

Este trabalho teve como objetivo avaliar os aspectos higiênico-sanitários de Unidades de Alimentação e Nutrição Escolares (UANE) de duas escolas públicas do município de Currais Novos (RN) quanto à adoção das Boas Práticas na Alimentação Escolar. Os dados foram coletados por meio de lista de verificação própria para UANE, durante as visitas realizadas nas unidades de uma escola estadual e uma municipal. As unidades avaliadas se encontravam em risco sanitário regular, com pontuações de 74% e 54% para a escola estadual e municipal, respectivamente. As principais inadequações encontradas foram relacionadas às edificações e instalações; aos manipuladores; à higienização dos hortifrutis e ao controle de pragas e vetores urbanos. Pode-se concluir que a produção de refeições nas UANEs das escolas avaliadas não atende a requisitos importantes previstos pelas Boas Práticas na Alimentação Escolar.(AU)

Data were collected through SFNU checklist, during visits to the units of a state and a municipal school. The health risk of units evaluated was regular, with scores of 74% and 54% for the state and municipal schools, respectively. The main inadequacies found were related to structure and facilities; food handlers; the hygiene of fruit and vegetables; and pest control and urban vectors. It could be concluded that the production of meals in SFNU of schools evaluated does not comply with important requirements established by the Good Practices in School Food and Nutrition.(AU)

Food safety knowledge, attitudes and practices of food handlers: A cross-sectional study in school kitchens in Espírito Santo, Brazil.

BACKGROUND: The adoption and evaluation of good practices in food handling in food service are essential to minimizing foodborne diseases. The present study aimed to evaluate food safety knowledge, attitudes, and practices of food handlers in schools in Vitória, Brazil. METHODS: A cross-sectional study was carried out in the school food services of the municipal network of Vitória-ES. The sample of food handlers was obtained by convenience and comprised food handlers involved with preparation and other kitchen-related activities. The instrument consisted of a structured questionnaire with 36 six questions that included sociodemographic characteristics, knowledge, attitudes, and practices (KAP) related to good practices and food safety. The questionnaire was answered by 172 food handlers. Pearson correlation test, T-test, Tukey's test and multiple linear regression analysis were conducted. Data entry and analysis were done using SPSS v.20 software. RESULTS: Most of the participants were female (96.5%, n = 166), were 40 to 49 years old (44.8%, n = 78), attended high school (57.9%, n = 99), had up to 5 years of experience in the role (39.5%, n = 68). Some of them had participated at least 4 times in training (74.4%, n = 128) of which the most recent session had occurred within 3 months (52.0%, n = 44). The lowest score was obtained for knowledge (7.1 ± 1.22). All the models presented significant results for the F-test. This result show good model fit and results ranging from 1.5 to 2.5 on the Durbin Watson test of residual autocorrelation. The linear regression analysis allowed us to identify that the knowledge score increased with experience, but it was significant only for those who had spent up to 10 years in the role. The knowledge score was associated with experience and training time. Attitudes were significantly related to the schooling and training time. The increase in the classification of practices is shown only through a classification of attitudes. CONCLUSIONS: Although the food handlers' knowledge level in general was considered as sufficient, it was inferior to their scores for attitudes and practices regarding certain food safety concepts. Food safety training is ongoing in these units and covers the main aspects that favour the transformation of knowledge into appropriate attitudes and practices.

Effect of dry sanitizing methods on Bacillus cereus biofilm.

Bacillus cereus is a relevant foodborne pathogen and biofilm producer which can contaminate and persist in the processing environment of both high and low water activity foods. Because of this, it is crucial to understand better the resistance of this pathogen biofilm to different sanitation methods. The aim of this study was to evaluate the efficacy of dry sanitizing treatments against B. cereus biofilm formed on stainless steel (SS) and polypropylene (PP). Biofilm formation was held through the static method at 25 °C. After 4 days of incubation, coupons were exposed for up to 30 min to UV-C light, dry heat, gaseous ozone, 70% ethanol, and a commercial sanitizer. Sodium hypochlorite (200 mg/l) was also tested in two different pH values (7 and 11) for comparison purposes. In general, the surface material did not influence (p > 0.05) the performance of the treatments. From 10 min of exposure, 70% ethanol and the commercial product caused the lowest reductions on both surfaces. In addition, dry heat exhibited a poor performance on PP, with reductions < 1 log CFU/cm2. UV-C light on SS and PP and ozone on PP achieved reductions around 2 log CFU/cm2 after 30 min. The same level of reduction was obtained after 5 or 10 min using sodium hypochlorite (200 mg/l). Therefore, the results showed that dry sanitizing methods are not as effective as sodium hypochlorite against B. cereus biofilms. Further studies to evaluate the efficacy of the combination of dry methods are necessary.

(AU)

The article discusses the hygienic quality of food commercialization, handling and consumption in light of necessary precautions to prevent contamination by SARS-CoV-2. The text draws attention to the health dimension of food security, which is little discussed in the public health field, despite being addressed in the National Food and Nutrition Policy. The relevance of the current research is substantiated by the association between hygienic-sanitary conditions in free fairs, supermarkets and restaurants by understanding them as risk areas for the spreading of the new virus, as well as guidelines published to help mitigating Covid-19 and the role played by Health Surveillance. Finally, it highlights the need of issuing regulations that take into consideration the sociocultural framework of agents inserted in the process and emphasizes the need of setting dialogue spaces to contribute to decode the concept of hygiene.

This study evaluated the good handling practices in the ten Hospital Nutrition Services of the respective hospitals in the South of Brazil, classified as general hospitals. For data collection, there was used a Checklist for Good Handling Practices for Food Services based on current legislation. Among the results, the average of adequacy of the hospitals stand out, showing that the items related to responsibilities and edifications had the lowest adequacies, 67% and 73%, respectively, followed by the food handler block, with 76% of adequacies. The block referring to food handlers showed that few of them sanitize the hands during the change of activity. The classification of hospitals in relation to Good Handling Practices was satisfactory, however, greater failure was observed related to the practices of the food handlers, which are crucial for the safety of food produced in Hospital Nutrition Services.(AU)

O bloco referente aos manipuladores de alimentos mostrou que poucos deles higienizam as mãos durante a troca de atividade. A classificação dos hospitais em relação à Boas Práticas de Manipulação foi satisfatória, no entanto, observou-se que falta o cumprimento de alguns itens, relacionados com as práticas dos manipuladores, que são cruciais para a segurança dos alimentos produzidos nos serviços de alimentação.(AU)

Trade and safety issues of raw beef from the countryside of Bahia state, Brazil.

Background: Brazil is one of the world's largest meat exporters. However, there is a paradox in this situation due to existing non-inspected meat trade and technical-sanitary failures in retail marketing. Design and methods: This study aimed at characterizing the issues of trade, food safety and quality of raw beef in the street market of a municipality in the state of Bahia. An exploratory, quantitative and census study was carried out, at 17 raw beef vending locations. A questionnaire was administered and meat samples were collected (n=34), which were submitted to a physicochemical assessment, color analysis and microbiological analyses. Results: Meat sellers were between 20 and 64 years of age, predominantly males (82.4%), with limited education and without professional training (64.7%). Medians for temperature and pH in the small butcher shops samples were 18.10ºC and 5.75 respectively, and 21.80ºC and 5.50, in small supermarkets samples. The difference in pH was significant (p<0.05). The filtration test suggested quality changes in 17.65% of the samples. No frauds were detected. Total coliform count medians were 4.90 and 4.78 log CFU/g, for the samples taken from butcher shops and supermarkets, respectively. E. coli was identified in approximately 40.0% of the samples. Salmonella spp. were confirmed in two samples collected in the butcher shops. There was a significant association between inadequate storage conditions and microorganism counts (p<0.02). Conclusions: The results evidenced a meat supply with preservation failures and non-compliance with hygiene requirements, constituting a consumers' health hazard, not in line with an agroexporting country model.

Análises de matérias estranhas e microbiológicas de chás industrializados comercializados em Pouso Alegre MG / Analysis of extraneous materials and microbiological from industrialized teas marketed in Pouso Alegre MG

O objetivo deste estudo foi de avaliar as condições higiênico-sanitárias de quatro marcas de chás industrializados comercializados na cidade de Pouso Alegre - MG utilizando parâmetros de presença de matérias estranhas e análises microbiológicas. Foram coletadas no período de setembro a outubro de 2017, amostras de chás de camomila, erva-doce, hortelã e chá misto que contém em sua formulação essas mesmas ervas. Foram utilizados os métodos da Association of Official Analytical Chemists International (AOAC) de acordo com a RDC n°14 para capturar as sujidades leves e nas análises microbiológicas, foram utilizados métodos da International Organization for Standardization (ISO) de acordo com a RDC n° 12 para avaliar coliformes totais e termotolerantes, fungos e Salmonella spp. Nas pesquisas de matérias estranhas somente três marcas de camomila foram aprovadas, estando o restante dos chás em desacordo com a legislação vigente por estarem acima do limite de tolerância aceitável. Na avaliação de coliformes e Salmonella sp. todas as amostras foram aprovadas porém, houve um crescimento considerável de fungos filamentosos nestas amostras...(AU)

The aim of this study was to evaluate the hygienic-sanitary conditions of four brands of industrialized teas marketed in the city of Pouso Alegre - MG using parameters of presence of foreign matter and microbiological analyzes. Were collected in the period from September to October 2017, samples of chamomile teas, fennel, mint and mixed tea that contains in its formulation these same herbs. Were used the methods of the International Association of Analytical Chemists (AOAC) according to RDC n° 14 to capture light dirt and in the microbiological analyzes, were used the methods of the International Organization for Standardization (ISO) according to RDC nº 12 to evaluate total and thermotolerant coliforms, fungi and Salmonella spp. In the research of extraneous materials, only three brands of chamomile were approved, the rest of the teas being in disagreement with the current legislation because they are above the acceptable tolerance limit. In the evaluation of coliforms and Salmonella sp. all samples were approved, however, there was a considerable growth of filamentous fungi in these samples…(AU)

Consumption, knowledge, and food safety practices of Brazilian seafood consumers.

The present work aimed to evaluate the frequency of seafood consumption by the Brazilian population, the safety practices during seafood handling and preservation as well as to evaluate the consumers' perception on the risks associated with these foods. A total of 962 respondents responded to a survey divided into three parts: demographic and socio-economic profiles, seafood consumption habits, safety practices, and risk perceptions regarding seafood. The survey revealed a low level of perception about seafood safety. The respondents (64-71%) demonstrated a lack of knowledge of the main pathogens associated with seafood disease outbreaks and presented difficulties in identifying consumption places that could result in higher microbiological risk. Besides, these respondents showed to be unaware of their responsibility towards seafood safety from purchasing through preparation. Respondents belonging to the generation of baby boomers, with the postgraduate level and females presented a better perception of microbiological risk and on the importance of safety practices. These respondents showed positive attitudes, such as knowledge of the proper thawing procedures of seafood, knowledge of the potential risks to get sick from the consumption of raw seafood, and were also able to recognize Vibrio and Listeria as seafood bacterial pathogens. The knowledge proves to be an adequate tool for perception and judgment of microbiological risk, making the consumer adopt safe practices. The instruction of seafood consumers about safe handling practices and perceptions is critical for the success of farm to fork preventive measures aiming to protect public health.

Street Food, Food Safety, and Regulation: What is the Panorama in Colombia?

ABSTRACT: Public management of street food is a challenge in many countries. In Colombia, despite the extent of the economic, social, and food contributions of the segment and the concern from the public health perspective, the amount of research on the subject still remains insufficient. Thus, this study aimed to establish a panorama of the street food trade in Colombia, considering its mode of operation, food security, and regulatory context, based on the scientific literature published between 2000 and 2018. A literature review was carried out in the Medline, SciELO, LILACS, Scopus, Redalyc, and Google Scholar databases, as well as in the University of Colombia's institutional repositories and scientific books. A set of 19 publications were selected and evaluated for three dimensions-work and culture, food safety, and regulation-according to the objectives and methodologies applied. In category 1, relative to work and culture, five studies were retrieved (26.3%), highlighting the economic and social contribution of the sector and the protection of food cultural heritage. Category 2, referring to hygiene and microbiological safety in the activity, covers 11 publications (57.9%) and comprised the largest research field of interest in the country. Among the food pathogens surveyed, Salmonella spp. were the most investigated, registering nonconformity in the samples (6.55%). Category 3, with three articles (15.8%), covered public policies and regulation of the segment, highlighting the challenges to regulating the sector and the need for intersectional articulation in administrative policies. The results confirm both the relevance of the segment to food security and the concern with microbiological hazards, demanding strategies to improve its regulation and functioning in the country, with the aim of protecting the health of consumers.

Hygienic-Sanitary Conditions of Hospital Nutrition Services in Southern Brazil

This study evaluated the good handling practices in the ten Hospital Nutrition Services of the respective hospitals in the South of Brazil, classified as general hospitals. For data collection, there was used a Checklist for Good Handling Practices for Food Services based on current legislation. Among the results, the average of adequacy of the hospitals stand out, showing that the items related to responsibilities and edifications had the lowest adequacies, 67% and 73%, respectively, followed by the food handler block, with 76% of adequacies. The block referring to food handlers showed that few of them sanitize the hands during the change of activity. The classification of hospitals in relation to Good Handling Practices was satisfactory, however, greater failure was observed related to the practices of the food handlers, which are crucial for the safety of food produced in Hospital Nutrition Services.
