Abstract
Mycotoxins are carcinogenic, mutagenic and teratogenic toxic metabolites that
are known to cause detrimental effect on the health of animals consuming its
contaminated feed. The objective of this study was to study the seasonal occurrence
of mycotoxins, aflatoxins (B1, B2, G1 and G2), citrinin, ochratoxin A and T-2 toxin
in feed and feed ingredients submitted to Pharmacovigilance Laboratory for Animal
Feed and Food Safety (PLAFFS). A total of 412 samples which included feed (289)
and feed ingredients (123) received during 2019-2020 were analyzed using thin
layer chromatographic method. Among the 249 positive samples, the incidence of
aflatoxin B1, aflatoxin B2, Aflatoxin G1 &G2, citrinin and ochratoxin A were 85.54%,
14.06%, 1.2%, 20.08%, 3.21% and 2.41% respectively and the concentration of
these mycotoxins ranged between 1.14 to 899.78 μg kg-1. Only few samples were
contaminated with aflatoxin G1 & G2, Ochratoxin A and T-2 toxin. Seasons had an
influence on the mycotoxin contamination and the highest incidence was detected
during winter, whereas, Citrinin and T-2 toxin were maximum at monsoon and
summer respectively. Regular monitoring of mycotoxin contamination in animal feed
is essential to prevent the entry of mycotoxins in the food chain.
