Descripción
The purposes of this study were to determine the distribution of total mycobiota, to determine the occurrence of Aspergillus spp., Penicillium spp. and Fusarium spp. and to detect and quantify fumonisin B1 and aflatoxin B1 in birds’ feedstuffs. Sixty samples from different commercial feeds were collected. Analysis of the total mycobiota was performed and total fungal counts were expressed as CFU g 1 . The isolation frequency (%) and relative density (%) of fungal genera and species were determined. Mycotoxins determination was carried out using commercial ELISA kits. The 48% of standard, 31% of premium and only 9% of super premium feed samples were found above of recommended limit (1 9 104 CFU g 1 ). Aspergillus (82%), Cladosporium (50%) and Penicillium (42%) were the most frequently isolated genera. Aspergillus niger aggregate (35%), Aspergillus fumigatus (28%) and Aspergillus flavus (18%) had the highest relative densities. Contamination with fumonisins was detected in 95% of total samples with levels from 092 to 668 lg g 1 , and the aflatoxins contamination was found in 40% of total samples with levels between 12 and 902 lg kg 1 . Feed samples contaminated with fumonisins and aflatoxins are potentially toxic to birds.
