The objective of this study was to determine the levels of aflatoxin B1 (AFB1) and total aflatoxins (AF) in broiler meat at market age. During one year period a total of 264 samples from 199 healthy and 65 sick flocks were collected. AFB1 residues in liver, kidneys and muscles of healthy birds were detected in 75.9, 44.7 and 21.6% samples, and the highest individual levels were 2.0, 0.99 and 0.49 ng/g, respectively. AFB1 residues in liver muscle and kidneys of sick birds were detected in 89.2, 70.8 and 55.4% and the highest individual levels were 7.99, 3.99 and 1.99 ng/g, respectively. The AFB1 residue level in 0.5% liver samples of healthy birds were 2 ng/g whereas in sick birds 23.1 and 6.2% of liver and kidneys had AFB1 residues above 2.0 ng/g. AFB1 levels in the muscles of both healthy and sick birds were below 2.0 ng/g. Among healthy birds none of the tissues had AF residue levels above 4 ng/g whereas in sick birds, 24.6 and 7.7% liver and kidneys had AF residues above 4.0 ng/g.
