20. Pesquisa de microorganismos indicadores e patogênicos no filé de tilápia do Nilo (Oreochromis niloticus) e em diferentes pontos da planta de processamento
Nile tilapia (Oreochromis niloticus) is one of the most important species for aquaculture because of its easily adaption to farming in different production systems, delicate taste and texture. However, there are not many slaughterhouses for Nile tilapia in Brazil because the production is still small and targeted mainly to local trade. The purpose of this st
