dc.descriptionAbstract: Nicarbazin (NCZ) is a worldwide used anticoccidial in poultry farming to avoid coccidiosis disease when chickens are reared on conventional poultry litter. If proper dosage and withdrawal time are not followed, the component dinitrocarbanilide (DNC) of NCZ may be present in chicken tissues, therefore posing a risk to consumers if the residues are above 200 ?g/kg. Litter reuse is a common and important practice in commercial chicken production. Literature is lacking about the influence of litter reuse on DNC deposition in chicken tissues and its impact on food safety. We aimed to evaluate DNC residues in breast and liver by LC?MS/MS from broilers from an experiment with 10 consecutive flocks during 2 years. The experiment included three treatments containing NCZ in the diet (T1 = 125 mg/kg, 1?21 d; T2 = 125 mg/kg, 1?32 d; T3 = 40 mg/kg, 1?32 d). DNC residues in chicken breast at 21 d in T1 ranged from 648.8?926 ?g/kg, at 32 d in T2 and T3 varied, respectively, from 232?667 ?g/kg and 52?189 ?g/kg. Regarding liver, DNC residues at 21 days in T1 ranged from 11,754?15,281 ?g/kg, at 32 days in T2 and T3 varied, respectively, from 10,168?15,021 ?g/kg and 2899?4573 ?g/kg. When NCZ was withdrawn from feed, DNC residues dropped to <LOQ at 42 d in all treatments. Therefore, the reuse of poultry litter does not compromise food safety regarding DNC residues in chicken tissues, as shown herein up to 10 flocks.
