A survey of the presence of residues of anticoccidials was performed. Three hundred and twenty egg samples, purchased in eight different European countries, were analysed for the presence of nine different compounds: dimetridazole, diclazuril, halofuginone, robenidine, nicarbazin, narasin, salinomycin, lasalocid and monensin. Analyses were performed by LC-MS/MS. Of the samples analysed, 114 (35.6%) contained one or more of the nine anticoccidials in concentrations ranging from 0.1 to 63 microg kg-1. Salinomycin and lasalocid account for more than 60% of all positive samples. Almost 90% of all positive samples contained less than 2 microg kg-1. Results were put into perspective of the farming method and country of origin.
