Abstract
Mycotoxins are toxic secondary fungal metabolites that can negatively affect animal productivity when ingested through feed. In
order to assess mycotoxin contamination of poultry feed and feed ingredients vis-a-vis source tracking of feed contamination in
Nigeria, 102 samples of feed (n = 30) and feed ingredients (n = 72) were collected from in-house mills of poultry farms across 12
states of Nigeria and analyzed for multiple mycotoxins using LC/MS-MS. One hundred and forty microbial metabolites were
detected in the feed and feed ingredients. The most frequent mycotoxin in the feed was fumonisin B1, occurring in 97% of the
samples at mean concentration of 1014 μg kg−1
. AFB1 occurred in 83% of the feed samples at mean concentration of 74 μg kg−1
and in all feed ingredients except fish meal and other cereals (millet and rice). Feed samples analyzed in this study were
contaminated with at least four mycotoxins: aflatoxins and fumonisin co-occurring in 80% of the samples. Peanut cake and
maize contributed the most to the levels of aflatoxin and fumonisin, respectively, in the feed. Consequently, there is a need to
explore other cereal- and protein-based ingredients for compounding feeds in order to reduce the risk associated with high
mycotoxin (e.g. aflatoxin) intake in poultry
