Abstract

Fungi and their storage conditions (moisture) and contamination by mycotoxins in foods offered to sheep were evaluated. Crioula animals created at Farm Ressacada – UFSC and with weakened health. The samples of alfalfa hay (Medicago sativa L.) were stored at 3 points (entrance of the shed, sheepfold and room), besides (b) pasture (B. decumbens) obtained in the field and (c) ration (Corn and soybean) stored in the sheepfold. The most detected fungal genus was Aspergillus, followed by Penicillium in 75 and 40% of the samples, respectively. Toxigenic strains (AFLs producers) were identified. As regards moisture (mc and aw) the contents ranged from 12-40% (mean: 12%) and aw: 0.5029-0.9888 (mean: 0.5783), considered adequate for fungal growth. Mycotoxins (AFLs: AFB1, AFB2, AFG1, AFG2) were detected at levels of 128 μg/kg in the hay samples. Cleaning conditions (warehouse and machinery) are of the utmost importance, since samples newly arrived at the shelter of the sheep are contaminated.
