Abstract


Total aflatoxin and aflatoxin B1 levels in feeds and feed ingredients of livestock and poultry in Kerala were analysed in 709 samples by fluorometry after extraction using specific monoclonal antibody based immune-affinity columns. The levels of total aflatoxin varied widely from 1 to 400 ppb in feeds and levels were found to be higher in poultry, duck and quail feeds when compared to their accepted dietary limits. Even though the levels of total aflatoxin varied from 1 to 680 ppb among different feed ingredients, the mean levels were found to be very high in maize (122 ± 53.36 ppb) and ground nut cake (139.75 ± 31.1 ppb). Aflatoxin B1 contributed to 66 to 82% of total aflatoxins in the feed. Total aflatoxin levels were found to be very high during the months of October and November (Northeast monsoon season).
