Resumo
A carcinicultura é uma atividade que vem se expandindo, assim como o consumo do camarão, considerado um alimento saudável por sua qualidade nutricional. Nesse contexto é importante garantir a oferta de um produto de qualidade microbiológica, que atenda às exigências do mercado alimentício e não ofereça riscos à saúde do consumidor. Assim, objetivou-se verificar a relação entre a contaminação do camarão Macrobrachium amazonicum e o ambiente de criação, além de comparar os resultados obtidos com a legislação vigente. Para tanto, foi verificada a qualidade microbiológica do camarão, sedimento e água do viveiro onde estes foram cultivados, enumerando coliformes totais e termotolerantes e Staphylococcus coagulase positiva, e verificando a presença de Escherichia coli patogênica e Salmonella spp. Os resultados evidenciaram que as amostras de água encontraram-se em conformidade com os limites estabelecidos pela legislação, enquanto que para camarão uma amostra estava fora do limite exigido para Staphylococcus coagulase positiva e para Salmonella spp. as demais apresentavam-se de acordo com a legislação. As amostras de camarão apresentaram correlação com a água e sedimento do viveiro, demonstrando que a contaminação microbiológica do viveiro reflete na qualidade do camarão. O monitoramento da qualidade da água e a adoção do manejo correto na carcinicultura assumem grande importância para garantir a produção de camarões de boa qualidade, atendendo às exigências do mercado para comercialização e a segurança na saúde do consumidor
Shrimp farming is an activity that is expanding, as well as the consumption of shrimp, considered a healthy food due to your nutritional quality. In this context, it is important to ensure the supply of a product of microbiological quality, which meets the requirements of the food market and does not offer risks to consumer health. Thus, this study aim to verify the relationship between contamination of shrimp Macrobrachium amazonicum and culture environment and to compare the results obtained with the Brazilian legislation for water and shrimp. Thereunto, we investigated the microbiological quality of the shrimp, sediment and water of the pond where they were grown, enumerating total and thermotolerant coliforms and Staphylococcus coagulase positive, and investigating the presence of pathogenic Escherichia coli and Salmonella. The water samples were obeying the limits established by legislation, while a sample of shrimp was out of range required for Staphylococcus coagulase positive and for Salmonella all samples were in accordance with the law. Samples of shrimp were correlated with the water and sediment of the pond, showing that the microbiological contamination of the pond reflects the quality of shrimp. The monitoring of water quality and the adoption of the correct management in shrimp farming are very important to ensure that shrimp production of good quality, acordding the market requirements and consumer health safety
