dc.description.abstractAflatoxin is a by-product of the metabolism of aspergillus fungi has severe health risks as indicated by many researchers. This study is aiming to examine the existence of aflatoxin B1 in two crops; corn and soybean which is the major raw material in poultry feeding concentrates. Both ingredients are imported and inter the manufacturing process in local factories. In this study 42 samples of corn and soybean were collected from siloes of concentrates processing factories for animal feeding located in Jenin, Nablus, and Tulkarm districts. The samples were collected in October, 2021. The samples were kept in cool dark containers and then sent to the lab analysis to test the concentration of Aflatoxin B1 according to the procedure of RIDASCREEN® Aflatoxin B1 30/15. The results indicated that aflatoxin B1 was detected in 80%, 100%, and 100% of the corn samples from Jenin, Nablus and Tulkarm consequently. While in soybean the existence of aflatoxin B1 was found in 60%, 85.7%, and 100% of the samples in Jenin, Nablus, and Tulkarm consequently. In corn samples; the overall average AFB1 concentration was 0.69 µg/kg, the average concentration is 0.64 µg/kg in Jenin, 0.604 µg/kg in Nablus, and 0.80 µg/kg in Tulkarm. These results are ithin the accepted levels according to the standards. Significant differences in the aflatoxin concentration of both crops were found between the three districts. In soybean sample; the overall average AFB1 concentration was 0.66 µg/kg. The average concentration is 0.78 µg/kg in Jenin, 0.61 µg/kg in Nablus, and 0.65 µg/kg in Tulkarm, which is within the accepted levels as indicated by the European and US FDA guidelines, which is 20 ppb ( 20 µg/kg).
