A total of 3230 samples of feed ingredients of vegetable and animal origin and commercially available compound poultry feed received over a period of 5 years at Feed Testing Laboratory of the Institute were tested for Aflatoxin B1 contents (ppb). In all feed ingredients and compound feed stuffs, minimum level of aflatoxin B 1 was 13 ppb and maximum level was found to be 78 ppb. No correlation of aflatoxin levels with month of collection of the year which are subject to variation in temperature and humidity could be detected. Mean values of aflatoxin concentration in feed stuffs such as rice, rice polish, wheat bran, wheat bread, maize, fish meal, blood meal, bone meal, guar meal, corn gluten 30%, corn gluten 60%, sun flower meal, soybean meal and cotton seed meal were found to be higher than safe level of 20 ppb recommended by FDA.
