ABSTRACT Aflatoxins (AF) are toxic fungal second-ary metabolites and are known mycotoxins pathologi-cal to animals and humans. Poultry litter is frequently used as a food supplement for ruminants, and when poultry feed contains AF, the litter becomes contami-nated as well, thus having an effect on livestock health. This study identified and quantified AF (AFB1, AFB2, AFG1, and AFG2) from poultry feed and their recovery, together with their metabolites (AFM1, AFM2, AFP1, and aflatoxicol) in litter. An experiment with 25 Hy-Line W-36 hens, in their second production stage, 121 wk old, was carried out. Hens were distributed in 3 groups placed in individual cages and 1 ration of 250 g of feed was given to each hen daily. Nine hens of the con-trol group were fed with clean feed, without AFB1; th
