ABSTRACT

Realizaram-se inspeção visual e avaliações bacteriológicas e físico-químicas da piramutaba, Brachyplatistoma vaillanti, congelada, eviscerada e sem cabeça, de 20 amostras compostas por um pool de três peixes dos dois principais distribuidores da região de Belo Horizonte, MG, sob as exigências legais. Salmonella ssp. e Staphylococcus aureus foram encontradas somente em amostras de um distribuidor, indicando que 10 por cento delas estavam impróprias para o consumo humano. Os resultados confirmam a baixa incidência desses patógenos na piramutaba. As bases voláteis totais estiveram dentro do limite exigido por lei, e os valores de pH apresentaram-se fora dos padrões legais em 90 por cento das amostras, nos dois distribuidores.


Visual inspection and bacteriological and physico-chemical evaluations were carried out in frozen, eviscerated, and headless piramutaba (Brachyplatistoma vaillanti). Twenty samples composed by a pool of three fish from the two main wholesalers of Belo Horizonte, MG, were studied. Salmonella ssp. and Staphylococcus aureus were only found in samples of one wholesaler, representing that 10 percent of the samples were inappropriate for human consumption. The results confirmed the low incidence of these pathogens in piramutaba. The total volatile bases were in accordance and the pH values were not in accordance with the law requirements in 90 percent of the samples.
