Abstract: Mycotoxins are a diverse group of chemicals that can affect many organ systems, mainly the liver, kidneys and nervous system. Mycotoxigenic fungi studied in this research were Aspergillus flavus, Aspergillus niger, Aspergillus fumigatus, Penicillium sp. and Fusarium sp. The objectives of this study understood the detection of mycotoxins and mycotoxigenic fungi in feeds sold in the city of Concordia (Santa Catarina). Analyses were performed according to the methodology of the Instituto Adolfo Lutz. The analysis included 18 samples in triplicate with a positive result for the presence of fungi in 13 of 18 samples (72.2%). The presence of Fusarium sp. was 9-13 samples (69.2%), A. niger (23.1%), A. flavus (7.7%), other unidentified species of fungi (46.2%). The presence of only one species of fungi occurred in 61.5% of samples while the presence of 2 species of fungi in 38.5% of samples. The presence of mycotoxins was detected in 11.1% of samples (deoxynivalenol). Thus, the method used to detect the presence of mycotoxins in feeds has proven reliable and moreover, characterized by being a quick detection test, serving as an important method of screening to test samples suspected of contamination by these substances.
