Coliformes totais e Escherichia coli em coxas de frango comercializados no Rio de Janeiro

Abstract

Os objetivos deste trabalho foram enumerar coliformes totais e Escherichia coli, que e um indicador de contaminacao fecal,comparando os resultados obtidos frente aos padroes de identidade e qualidade nacionais vigentes, alem de realizar asorologia das cepas de E. coli isoladas em coxas de frango, obtidas em estabelecimentos com e sem inspecao sanitaria,comercializadas no municipio do Rio de Janeiro. Para enumeracao dos microrganismos foi utilizada metodologia miniaturizadacom meios de cultura de rapida deteccao, contendo indicadores fluorogenicos e cromogenicos. Das 30 amostras analisadas,12 apresentaram numero mais provavel (NMP) de E. coli variando de <3 a 2,9x107/g, sendo seis (20%) consideradas impropriaspara o consumo de acordo com a legislacao vigente. Das 150 colonias suspeitas e confirmadas em testes bioquimicos 18(12%) foram positivas para os sorogrupos E. coli enteropatogenica (EPEC) e E. coli enteroinvasiva (EIEC), provenientes de 15amostras diferentes. Das 17 colonias suspeitas para E. coli enterohemorragica (EHEC), nenhuma cepa pertencia a estegrupo. Os resultados indicam que a existencia de um servico de inspecao eficiente, em todas as fases do processo tecnologicodo frango, e muito importante para obtencao de um produto de qualidade e seguro, sem riscos para a saude do consumidor.
