This research was carried out to monitor the occurrence of aflatoxins (B1, B2, G1, and G2) in unpacked rice (50 samples) and cattle feed (60 samples). These samples were analyzed using TLC & ELISA techniques. 30% rice samples showed aflatoxins (AFTs) in the range of 1-20 ppb while 10% samples showed AFTs above 20 ppb. For cattle feed, AFTs detected in the range of 1.9-20.4 ppb in maize, 9.6-28.5 ppb in corn, 9.8-27.3 ppb in barely, 5.4-21.3 ppb in hay samples and 6.7-28.5 ppb in silage samples. The contaminated samples were treated for detoxification. The detoxification promised by specific natural compounds like sodium bicarbonate, citric acid, Allium sativum and black seed oil were from 63-100%. The foods contaminated with AFTs are toxic for human health. High doses of AFTs can be the major cause of liver diseases like cirrhosis, liver cancer and death in humans and animals.
