Occurrence of aflatoxins and zearalenone in feedstuffs destined to dairy cattle consumption in Northern Parana, Brazil/ Ocorrência de aflatoxina e zearalenona em alimentos destinados ao gado leiteiro na Região Norte do Estado do Paraná

Abstract

Molds occur in a wide range of foods and feedstuffs, including roughage and grains destined to animal consumption, and may produce mycotoxins under certain conditions. This work intended to survey the presence of mycotoxins aflatoxin and zearalenone in feedstuffs destined to dairy cattle consumption in the region of Northern in the Paraná state, Brazil, using thin layer chromatography. Of the 272 samples analyzed for aflatoxins, 37 (13,6%) were positive with 20 (7,3%) above the limit of 20¼g/Kg determined by ANVISA. Of the 189 samples analyzed for zearalenone, 32 (16,9%) were positive and all were above 200¼g/Kg, which is the recommended limit in the surveyed region. Contamination by aflatoxins occurred more in grains, while zearalenone occurred more in roughages.Os fungos ocorrem em uma grande variedade de alimentos, inclusive nos volumosos e concentrados destinados à alimentação animal, e podem produzir micotoxinas sob certas condições. O presente trabalho teve por objetivo avaliar a presença das micotoxinas aflatoxina e zearalenona em alimentos fornecidos a bovinos de exploração leiteira na região Norte do Estado do Paraná, Brasil, utilizando como metodologia analítica a cromatografia em camada delgada. Das 272 amostras analisadas para aflatoxinas, 37 (13,6%) foram positivas, sendo 20 (7,3%) acima do limite de 20mg/Kg determinado pela ANVISA. Das 189 amostras analisadas para zearalenona, 32 (16,9%) amostras foram positivas, e todas estavam acima do limite de 200mg/Kg recomendado pelos veterinários da região norte do Paraná, Brasil. Foi encontrada maior contaminação por aflatoxinas em alimentos concentrados, enquanto que por zearalenona ocorreu em alimentos volumosos.
