This study describes the effect of dietary levels of aflatoxin B1 (AFB1) and age of the birds upon the residue level in liver and muscles of broiler chicks. In three different experiments broiler chicks of 7, 14 and 28 days of age were kept for 7 days on contaminated rations having 1600, 3200 and 6400 mu g/kg AFB1. AFB1 residues were detected earlier in younger birds and those fed high AFB1 dietary levels. The highest residue levels in liver and muscles of young chicks fed 6400 mu g/kg AFB1 was 6.97 +/- 0.08 and 3.27 +/- 0.05 ng/g, respectively. Maximum residue concentration was high in birds of young age and those kept on high AFB1 ration. After withdrawal of AF contaminated rations, residues clearance was slow and AFB1 was detectable in liver and muscles of birds for longer duration in younger birds and those fed high AFB1 dietary levels. AFB1 residues in poultry tissues may buildup to high levels in areas with no regulatory limits on AFB1 levels of poultry feed and may pose a risk to consumers health. (C) 2010 Elsevier Ltd.
