Ocorrência de Campylobacter spp. em carne e miúdos de frango expostos ao consumo em Belém, Pará Occurence of Campylobacter spp. in chicken meat and giblets exposed to consumption in Northern Brazil

<abstract language="eng">In order to study Campylobacter in chicken meat exposed to consumption in the city of Belém, state of Pará, Brazil, 16 samples (four of liver, four of gizzard, two of heart, two of skin, one of neck, two of carcass and a mixture of neck skin and fragments of the abdominal cavity), collected in clandestine butcher shops, fair-free and supermarkets were submitted to isolation and identification according to the recommended methods. In high percentage, the foods exposed to consumption were contaminated by this agent, meaning a potential risk to the human health

Survey of chicken abattoir for the presence of Campylobacter jejuni and Campylobacter coli Pesquisa de Campylobacter jejuni e Campylobacter coli em abatedouros de aves

The genus Campylobacter is of great importance to public health because it includes several species that may cause diarrhea. These species may be found in water, food and in the intestinal tract of chickens. This study investigated the presence of Campylobacter jejuni and Campylobacter coli in chicken abattoirs in São Paulo State, Brazil. A total of 288 samples of feces, feathers, scald water, evisceration water, chiller water, and the rinse water of eviscerated, not eviscerated and chilled carcasses were collected in six chicken abattoirs. Polymerase Chain Reaction (PCR) was performed in Campylobacter spp.-positive isolates using the gene HIP, specific for hippuricase enzyme from Campylobacter jejuni and aspartokinase gene, specific to detect Campylobacter coli. The percentage of positive isolates of Campylobacter jejuni was 4.9% (14/288). Isolation was greater in feces samples (22%, 8/36). One sample was positive for the species C. coli. In conclusion, the results indicate that it is necessary to improve quality control for Campylobacter spp. in chicken abattoirs.<br>O gênero Campylobacter tem grande destaque em saúde pública, principalmente por pertencerem a este gênero várias espécies que podem causar diarréia. Estas espécies podem ser encontradas em amostras de água, alimentos e no trato intestinal das aves. Este estudo investigou a presença de Campylobacter jejuni e Campylobacter coli em abatedouros de aves no Estado de São Paulo. As 288 amostras foram coletadas em seis estabelecimentos e incluíram: fezes; penas; água de escaldamento, de evisceração e de resfriamento; e água de enxaguadura de carcaça não eviscerada, eviscerada e resfriada. Após o isolamento microbiológico das amostras positivas de Campylobacter spp. foi realizada uma Reação em Cadeia da Polimerase (PCR) utilizando o gene HIP, da hipuricase, específico para Campylobacter jejuni e o gene da enzima aspartoquinase, específico para Campylobacter coli. A porcentagem de amostras positivas para Campylobacter spp. foi de 4,9% (14/288), sendo que o isolamento foi maior em amostras de fezes (22%, 8/36). Foi isolada uma amostra positiva para C. coli. Em conclusão, os resultados indicam que há uma necessidade de melhorar a qualidade higiênico-sanitária do controle de Campylobacter em abatedouros de aves

Salmonella spp. em carcaças, carne mecanicamente separada, lingüiças e cortes comerciais de frango Salmonella spp. in carcasses, mechanically deboned meat, sausages and chicken meat

Alimentos de origem animal representam papel fundamental na epidemiologia das salmoneloses humanas. Apesar dos avanços tecnológicos, a carne de frango ainda é passível de contaminação bacteriana, especialmente por microrganismos do gênero Salmonella, que podem encontrar-se albergados no trato intestinal ou em outra parte do corpo das aves. O presente trabalho objetivou pesquisar a ocorrência de Salmonella em carne de frango e derivados procedentes da região Nordeste do Estado de São Paulo. Foram analisadas, através do método convencional de cultivo, 45 amostras de carcaças, 60 de carne mecanicamente separada (CMS), 25 de lingüiça de frango, 20 de peito, e 15 de coxa e sobre-coxa. Salmonella spp. foi encontrada em 13,3% (6/45) das carcaças, 25% (15/60) das amostras de CMS, 16% (4/25) das lingüiças, 30% (6/20) dos peitos e 13,3% (2/15) das coxas e sobre-coxas analisadas. Do total de 165 amostras analisadas, 33 (20%) apresentaram contaminação por Salmonella estando, portanto, impróprias para o consumo conforme legislação brasileira.<br>Food of animal origin represents an important role in the epidemiology of human salmonellosis. In spite of the technological improvement, the chicken meat is subjected to bacterial contamination, mainly by microorganisms of the genus Salmonella that can be found in the intestinal tract or elsewhere on the chicken body. The aim of this study was to investigate the occurrence of Salmonella in chicken meat and cuts from the Northeast region of São Paulo State, Brazil. By conventional cultivation microbiological methods, 45 samples of carcasses, 60 samples of mechanically deboned meat (MDM), 25 samples of chicken sausages, 20 samples of chest, and 15 samples of chicken leg and thigh. Salmonella was found in 13.3% (6/45) of the carcass, 25% (15/60) of the MDM, 16% (4/25) of the sausages, 30% (6/20) of the chests and 13.3% (2/15) of the tight analysed. The results showed that 33 (20%) out of 165 samples were contaminated by Salmonella. Therefore, these samples were inappropriate for consumption, according to the Brazilian legislation
