Determination of mycotoxin and veterinary drug residues in packaged and ready-to-eat duck products

In recent years, duck meat products have been widely promoted in supermarkets and retail outlets, because of their distinctive flavor. The research aimed to assess the mycotoxin content and veterinary drug residues in duck meat purchased from 8 markets in Taizhou, China. Aflatoxin B1(AFB1), Aflatoxin M1(AFM1), Ochratoxin A(OTA), Ochratoxin T-2(OTAT-2), Vomitoxin, Zearalenone, Gentamicin and Streptomycin were detected using enzyme-linked immunoassay kits. In general, the mycotoxins, veterinary drugs, and the total number of colonies in duck gizzards were the highest in the five kinds of duck samples, while the mycotoxins and veterinary drugs in duck palms were lowest. Compared with the data on packaged duck products and ready-to-eat duck products, mycotoxin content in packaged duck meat products was higher than that in ready-to-eat duck products. Six kinds of mycotoxins and two kinds of veterinary drugs were detected in all 40 samples, the detection rate was 100%. The data from these samples confirmed that mycotoxins and veterinary drugs had high coexistence. The correlation analysis of the data showed that the content of mycotoxin was positively correlated with the residues of veterinary drugs, and the mycotoxin content was inversely proportional to the colony count.
