RESUMO
Resumo No Brasil, no Paraná, a produção de alimentos de origem animal é uma das atividades econômicas que mais contrata força de trabalho, mas, também, é uma das que mais contribui para a ocorrência de adoecimentos, porém ainda se tem pouco conhecimento sobre os transtornos mentais. Trata-se de uma pesquisa epidemiológica de caráter descritivo acerca de transtornos mentais e comportamentais em trabalhadores de indústrias de abate de suínos, aves e outros pequenos animais do estado do Paraná. Foram utilizados dados secundários da Previdência Social brasileira, de 2008 a 2014. Os resultados apontaram que a maioria dos trabalhadores incapacitados têm entre 28 e 38 anos, são mulheres e apresentam prevalência de depressão. Houve prevalência do benefício auxílio-doença previdenciário em detrimento do auxílio-doença por acidente de trabalho, que possui nexo com o trabalho. Além disso, redução anual dos benefícios acidentários concedidos. Conclui-se que há dificuldade dos trabalhadores em obter o reconhecimento da doença como decorrente do trabalho, especialmente quando caracterizadas como transtornos mentais.
Abstract In Paraná, Brazil, the production of food of animal origin is one of the economic activities that most employs the workforce, but it also most contributes to the emergence of illnesses; however, there is little knowledge concerning mental disorders. This study is a descriptive epidemiological investigation on mental and behavioral disorders in workers at pig and poultry slaughterhouses in the department of Paraná. Secondary Brazilian Social Security data from 2008 to 2014 was used. The results indicate that the majority of disabled workers are between 28 and 38 years, are women and show signs of depression. There was a prevalence of social security benefits for illness in comparison with benefits for work-related accidents. In addition, there was an annual reduction of accident benefits granted. The study concludes that it is difficult for workers to receive recognition of work-related illnesses, especially for mental disorders.
Resumen En Paraná, Brasil, la producción de alimentos de origen animal es una de las actividades económicas que más ocupa fuerza de trabajo, pero también es la que más contribuye a la aparición de enfermedades; sin embargo, aun se tiene poco conocimiento acerca de los trastornos mentales. Se trata de una investigación epidemiológica de carácter descriptivo sobre trastornos mentales y de conducta en trabajadores de mataderos de porcinos, aves y otros pequeños animales del departamento de Paraná. Se utilizaron datos secundarios de la Seguridad Social brasileña, de 2008 a 2014. Los resultados señalan que la mayoría de los trabajadores discapacitados tienen entre 28 y 38 años, son mujeres y presentan prevalencia de depresión. Hubo prevalencia del beneficio de seguridad social en salud por enfermedad en comparación con beneficio por enfermedad por accidente de trabajo, que posee nexo con el trabajo. Además, la reducción anual de los beneficios accidentarios concedidos. Se concluye que hay dificultad de los trabajadores en lograr el reconocimiento de la enfermedad como consecuencia del trabajo, en especial cuando se caracteriza como trastorno mental.
RESUMO
Background: Salmonellosis is one of the most prevalent foodborne diseases worldwide. Although listeriosis has been quite less reported, it is considered a major public health hazard due to the severity of symptoms caused in humans. Previous studies demonstrated that the genus Listeria and Salmonella can be found infecting pigs in Brazil, however there are yet few reports about their isolation from carcasses after the slaughtering process. From this, the aims of this study were to investigate the presence of Salmonella enterica and Listeria monocytogenes on pre-chill pig carcasses and to evaluate the presence of fecal carriers at the lairage. Materials, Methods & Results: Two sampling events were conducted in each of three slaughterhouses located in the state of Santa Catarina, Brazil. In each sampling event, pen feces from pigs belonging to three slaughter batches originated from different farms were collected. Thereafter, swabs were taken on the surface (loin, jowls, belly and ham) of 42 carcasses belonging to the same pig batches sampled at the lairage. All samples were submitted to a protocol for isolation of S. enterica and L. monocytogenes. Moreover, coliforms were enumerated in the samples taken from the carcasses. From a total of 18 samples of pen feces, 83.3% (15/18) were positive for S. enterica. The genus Listeria was isolated from 66.7% (12/18) of pen feces samples, but only one isolate was confirmed as L. monocytogenes. Among the 252 pre-chill carcasses sampled, S. enterica was isolated from 27.4% (69/252); and S. Typhimurium was the most frequent serovar identified. On the other hand, L. monocytogenes was detected in 19.8% (50/252) of the carcasses. In slaughterhouse B, a signifi cantly higher frequency (P < 0.001) of L. monocytogenes isolation than in the other slaughterhouses was observed. S. enterica was significantly more (P < 0.001) isolated than L. monocytogenes in the other two sampled slaughterhouses. The coliform mean counts found on carcass samples ranged from 1.25 x 100 to 8.25 x 104. In slaughterhouse A, the coliform mean was significantly lower (P < 0.001) than the mean of coliforms determined in the other slaughterhouses. Discussion: The significantly higher frequency of L. monocytogenes isolation from carcasses sampled at the slaughterhouse B suggests that there were flaws in its slaughter process. Nevertheless, the L. monocytogenes contamination on the carcasses may not have been originated from feces, since this Listeria specie was found in only one sample of pen feces. In spite of the fact that slaughterhouse A presented a significantly lower mean of coliforms on the pre-chill carcasses, indicating that there was a better hygiene in the slaughtering process, the frequency of S. enterica on the carcasses was not different in comparison to those found in the other sampled slaughterhouses. This result may be related to the large number of fecal carriers detected at the lairage, which in turn may have led to an increase on the carcass contamination hazard throughout the slaughter line. In conclusion, S. enterica and L. monocytogenes can be isolated from pre-chill pig carcasses. Whereas the high number of Salmonella fecal carriers may have contributed to the frequency of contaminated carcasses, L. monocytogenes strains found on carcasses were probably not originated from feces.
