Résumé
"Residues of 9 antimicrobial agents approved in México for veterinaryuse in dairy cattle (sulfathiazole, sulfamerazine, sulfamethazine,sulfachloropyridazine, sulfamonomethoxine, sulfamethoxazole,nitrofurazone, furaltadone, and furazolidone) and non-approvedchloramphenicol residues were studied every two weeks infour commercial brands of Mexican pasteurized milk (A, B, C andD) during one year (n=4×24=96). Drug residues were analyzed byhigh pressure liquid chromatography HPLC with UV detection. Percentageof positive samples to sulfonamide residues were 47.2%(Milk A), 58.3% (Milk B), 44.7% (Milk C) and 50% (Milk D). Sulfonamideresidues ranged between 1.9 and 180µg/kg. sulfathiazoleand sulfamerazine were the most common residues found. Onlythree samples (Milk B) exceeded maximum residue levels establishedfor sulfonamides. Nitrofuran residues were not detected inany milk sample. Illegal Chloramphenicol residues were detected inone milk sample (Milk A) in levels of 27.2µg/kg."
