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% 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% of the samples.
