Abstract:
Objective To understand the situation of corn mycotoxins contamination in Heilongjiang Province , and to analyze the causes of pollution and propose prevention and control measures. Methods Among the 473 corn samples were collected from various regions in Heilongjiang Province , and 16 mycotoxins , including aflatoxins , fumonisins, deoxynivalenol and their metabolites , zearalenone , ochratoxin A , alternariol , alternariol monomethyl ether , tentoxin , and tenuazonic acid , were detected in the corn samples. The detection and quantification were carried out using ultra-high performance liquid chromatography tandem mass spectrometry isotope internal standard method. Results All samples were detected with mycotoxins, the detection rate was 100%, and each sample was contaminated by one or more mycotoxins. The detection rate of 16 mycotoxins ranged from 0.21% to 98.31%. The average contamination level ranged from 0.67 μ g/kg-259.19 μ g/kg. Three types of toxins exceeded the standard, with exceeding rates of deoxynivalenol (2.54%, 12/473), zearalenone (4.02% ,19/473), and fumonisins (2.54%,12/473), respectively. The samples exceeding the standard were distributed in Mudanjiang, Shuangyashan, Jixi, Harbin, and Qiqihar. Conclusion Corn in Heilongjiang Province is contaminated by a combination of mycotoxins. It is necessary to strengthen monitoring from multiple links and adopt a variety of ways and control measures to reduce corn contamination.
