Abstract

The livestock feed and feed ingredients were screened for the presence of aflatoxin B1, citrinin, penicillic Acid, T2, ochratoxin A and zearalenone. The samples were collected from different livestock farmers/farms of Tamil Nadu. Mycotoxins were determined in all the samples. The present study clearly indicates high occurrence of citrinin highly predominant followed by Aflatoxin B1 and ochratoxin A in feedstuffs and feeds. Aflatoxins B1, citrinin, ochratoxin A were the most common mycotoxins observed. The aflatoxin B1 levels ranged between 50 to 80 ?g kg^-1, ochratoxin A levels ranged between 20 to 160 ?g kg^-1, Citrinin levels ranged between 20 to 350 ?g kg^-1, penicillic acid levels ranged between 20 to 30 ?g kg^-1, T2 Toxin levels ranged between 75 to 450 ?g kg^-1?and zearalenone levels ranged between 150 to 1000 ?g kg^-1?respectively.? The results of the study warrant the need for sustained monitoring of these commodities periodically and evolve policies which discourage the marketing of toxin contaminated feeds as existing in the developed countries.
