Abstract
- In this study Aflatoxin B<subscript>1</subscript> (AFB<subscript>1</subscript>), ochratoxin A (OTA) and zearalenone (ZEN) occurrence in fish feed, regarding its chemical composition, were investigated. Besides, AFB<subscript>1</subscript> bioaccessibility to fish was evaluated by in vitro digestion. Mycotoxins were extracted by QuEChERS and quantified by HPLC-FLD. Results showed that 93.3% of the samples were contaminated at maximum levels of 16.5, 31.6, and 322 µg/kg in the cases of AFB<subscript>1</subscript>, OTA, and ZEN, respectively. A positive correlation between OTA, ZEN contamination, and lipid content was observed. Risk estimation of feed consumption by fish at the highest levels of AFB<subscript>1</subscript>, OTA, and ZEN shows that the younger the fish, the higher the risk of exposure to mycotoxins. The AFB<subscript>1</subscript> bioaccessibility assay showed that 85% of this mycotoxin may be absorbed by fish. Therefore, establishing maximum levels in the fishing sector is fundamental to contribute to feed quality and nutritional safety of fish species. [ABSTRACT FROM AUTHOR]
