Effect of γ-irradiation on fumonisin producing Fusarium associated with animal and poultry feed mixtures.

ABSTRACT: Contamination of animal and poultry feeds by Fusarium and the mycotoxin Fumonisin B1 is frequent in the feed supply chain. The present study evaluated the prevalence of fumonisin B1 producing Fusarium among irradiated and non-irradiated animal and poultry feed mixtures. Further, the efficiency of γ-rays (2.5, 5.0, 7.5, and 10.0 kGy) to minimize Fusarium growth and biosynthesis of fumonisin B1 in artificially inoculated feed was evaluated. A total of 108 feed samples were collected in which 45.37% of feed mixtures were contaminated with Fusarium species. Among the contaminated samples, the frequency levels of F. verticillioides and F. proliferatum were 42.59 and 24.07%, respectively. Out of the 98 Fusarium isolates from feed samples, 84.7% of F. verticillioides and 64.28% of F. proliferatum
