Investigation on veterinary drug residues of local characteristic dairy products and dairy-containing products in Inner Mongolia

Abstract

ObjectiveTo provide a scientific basis for the risk assessment of the dietary exposure of local characteristic dairy products and veterinary drug residues in dairy products in Inner Mongolia and the formulation and revision of local food safety standards， the current situation regarding this matter was studied.MethodsA total of 951 samples of seven types of local characteristic dairy products and dairy-containing products in Inner Mongolia were collected in 12 league cities， including milk skins， milk tea powder， and chewable milk products. Among them， 370 samples were in bulk and 581 samples were in standardized packaging. The samples were analyzed for quinolones， tetracyclines， macrolides， and β-sulfonamides.ResultsThe detection rate of veterinary drug residues was 0.83%-3.62% in five types of local characteristic dairy products， including milk skin， milk tea powder， chew， chula， and milk-containing solid molding products. The detected veterinary drugs were naphthyric acid， norfloxacin， pefloxacin， sulfamethoxazole， sulfamethoxazole， sulfamethoxazole， and tylosin， with the detection rate ranging from 0.11% to 1.37%. According to the statistical test， there was no statistical difference between the detection rate of veterinary drug residues in bulk samples and that of veterinary drug residues in stereotyped packaging samples （χ2=0.484， P>0.05）.ConclusionAlthough the overall qualification rate of tetracycline， sulfonamide， and macrolide residues in local characteristic dairy products in Inner Mongolia is relatively high （>99%）， there are still cases of veterinary drug detection. It is recommended that relevant departments further strengthen the promotion and supervision of veterinary drug use.
