Anthelmintics residues in raw milk. Assessing intake by a children population

Abstract

Anthelmintics, such as benzimidazoles and probenzimidazoles, are veterinary drugs used against endoparasites in food producing animals. A number of these drugs are considered responsible for embryotoxicity and teratogenicity. The residue levels of Albendazole, Febantel, Fenbendazole, Mebendazole and some of their metabolites (Albendazole sulphoxide, Albendazole sulphone, Fenbendazole sulfone) were assessed in 123 (42 goat, 69 sheep, 12 bovine) raw milk samples collected from all farms throughout Southern Greece. Sample analysis was performed by HPLC with Diode Array Detector. A high percentage (27.6%) of the samples examined was found to be positive for the investigated compounds. In 14 samples (11.4%), the residues' concentration exceeded the established Maximum Residue Limits. Estimated Daily Intakes were calculated for a population of 723 children aged 10-12 years. Data on milk consumption were obtained by personal interview through a 7-day food frequency questionnaire. The maximum Estimated Daily Intakes for the anthelmintic residues, concerning raw milk, did not exceed the current Acceptable Daily Intake.
