Abstract:

To reveal the sulfadimidine (SM2) residue in main animal-source products in Guangxi,4 637 samples were collected from 2013 to 2017,and were detected by the method of SM2-CLEIA.A total of 122 samples,involving milk,pork,aquatic product and swine urine,were detected to have SM2 residue above the national standards,of which 92 were swine urine,with contents ranging from 100.51 to 860.44 μg/kg.Antibiotic residues in swine urine could contaminate water and soil,and thus enter the food chain,and their enrichment effects through animals and vegetables would be harmful to human health,which deserved due attention.Samples of buffalo milk,chicken livers,duck livers and duck meat all met standard in the tests.A survey of sources of the 122 samples displayed that the average amount of SM2 residue was decreasing annually,and that the qualified rates of the samples from intensive livestock farms were higher than those from individual farms,and those from supermakets were higher than those from farm's markets.The content of SM2 residue in samples taken in 2014 was the highest over the five years.IFS was employed to evaluate the safety of animal-derived foods in Guangxi,and the results were far less than 1,showing that the potential risk of SM2 residues to the human body was low in Guangxi.

Key words: animal-source products; sulfadimidine(SM2); residue
