One hundred eighty one samples of food and feed products were collected from some provinces in northern Vietnam. Natural occurrence of aflatoxin B<SUB>1</SUB> and ochratoxin A were surveyed in 26 samples of peanut kernel, 55 samples of animal feed, 20 samples of peanut products including peanut candy and fried peanut, 15 samples of soybean products including soybean powder, compressed soybean cake and soybean meat, 15 samples of maize products including nutrient corn powder and fried maize, 18 samples of coffee products including instant coffee and coffee berry, 16 samples of cashew nut products including cashew nut powder, cashew nut cake and cashew nut pigment powder, and 16 samples of meat products including crustaceous meat. Aflatoxin B<SUB>1</SUB> and ochratoxin A were analyzed according to an AOAC method and the modified AOAC method of Doronina and Makshimenko. Two of nine samples of peanut products in Hanoi city were contaminated with aflatoxin B<SUB>1</SUB> at an average concentration of 6μg/kg. One of five samples of peanut products in Haiphong city and one of six of those in Thanh hoa province were contaminated with aflatoxin B<SUB>1</SUB> at the level of 4 and 5μg/kg, respectively. Ochratoxin A was not detected in 20 peanut product samples. Neither aflatoxin B<SUB>1</SUB> nor ochratoxin A was detected in 80 samples including 15 soybean product samples, 15 maize product samples, 18 coffee product samples, 16 cashew nut product samples and 16 meat product samples. Thirteen of 26 peanut kernel samples and 35 of 55 animal feed samples were contaminated with aflatoxin B<SUB>1</SUB> at average concentrations of 43μg/kg and 12μg/kg, respectively.
