Screening of aflatoxin B1 and mycobiota related to raw materials and finished feed destined for fish
The aim of the present study was to determine fungal genera, Aspergillus, Pénicillium and Fusarium species and aflatoxin B1 contamination from raw materials and finished feed intended for fish farm localized in Piaui, Brazil. Aspergillusflavus and P. citrinum were isolated with a high relative densi...
