Toxigenic mycobiota and mycotoxins in shrimp feed

Abstract

The objective of this study was to identify the toxigenic mycobiota and the occurrence of aflatoxins in shrimp feed products intended for shrimp cultivated in the coastal area of the state of Piauí, Brazil, in three farms ("A", "B" and "C") RESUMO O objetivo deste estudo foi identificar a micobiota toxigênica e a incidência de aflatoxinas em rações comerciais para camarão cultivado no litoral do Estado do Piauí, Brasil, em três fazendas ("A", "B" e "C"). Foi realizada a capacidade toxigênica das espécies de fungos isolados e a produção de aflatoxinas (AF) e ocratoxina A (OTA). As contagens fúngicas da ração foram semelhantes nas fazendas "A" e "B" e em todas as fases de cultivo, locais de coleta e de embalagens fechadas e abertas (1,33-2,66UFC

Saccharomyces cerevisiae as a probiotic agent and a possible aflatoxin B1 adsorbent in simulated fish intestinal tract conditions

“…Among the species diversity, the fish known as tambaquis (Colossoma macropomum) stands out for its easy adaptability to different environmental and handling conditions, presenting as a highlight of the global fishing industry. Mycotoxin contamination in aquatic species occurs mainly by ingestion of contaminated feed, as increase in vegetable use in feedstuffs has increasingly caused the presence of these toxic substances in these products (Calvet et al, 2015).…”
