A survey was carried out on the occurrence of dinitrocarbanilide (DNC) the marker residue for nicarbazin, in poultry produced on the island of Ireland during the years 2002 to 2004. Liver (n = 736) and breast muscle samples (n = 342) were tested. DNC residues were determined in 40% and 26% of liver and breast muscle samples at levels greater than 12.5 and 5 μg kg-1, respectively. DNC residues were determined at >200 μg kg-1 in 12 and 0% of liver and muscle samples, respectively. Samples of breast muscle (n = 217) imported from 11 countries were also tested for DNC residues. A lower incidence of DNC residues (6%) was determined in imported breast muscle. Egg samples (n = 546) were tested and DNC residues were determined in nine samples, with levels ranging between 14 and 122 μg kg-1. Analysis of poultry, carried out as part of official food inspection in the period 2004 to 2006, indicates a reduction in the number of broiler liver samples containing DNC at >200 μg kg-1, to approximately 7%. Low levels of DNC residues continue to be determined in <2% of egg samples.
