Abstract:
A large-scale study was conducted to explore AFB1 contamination in feed samples using Thin Layer Chromatography, following an AOAC protocol. Samples were identified which were not compliant with the maximum limits for AFB1 as regulated in the United States and Pakistan. Of a total of 923 samples, 51 samples (5.5%) were not compliant according to Pakistan and 267 (28.9%) were not compliant with US-FDA standards. The overall prevalence of non-compliant samples of compound feed was 26.2% (n = 117) according to US-FDA standards, while none of the samples were non-compliant according to Pakistan standards. Among feed ingredients, the overall prevalence of non-compliant samples was 10.7% (n = 51) and 31.4% (n = 150) according to Pakistan and USFDA standards, respectively. Non-compliant feed with respect to AFB1 contamination was highly prevalent in Khyber Pakhtunkhwa, posing a serious threat to production performance and animals health.
