Cattle topical preparations

In addition, specific testing was performed for chloramphenicol in muscle, nitrofurans in muscle and serum, dimefridazole in muscle of pigs and poultry, and sulfonamides in liver. In Australia, chloramphenicol is not registered for use in food animals and nitrofurans are only available as a topical preparation for use in companion animals. No residues of either of these compounds were detected. No residues of dimefridazole were detected in pig and poultry samples. Sulfonamide residues were monitored in cattle and pigs. No residues were detected in 613 cattle samples. In 594 pig liver samples analyzed, 9 residues of sulfamethazine (sulfamethazine) were detected, 4 of which were above the MRL.
