摘要： Emerging Alternaria and Fusarium mycotoxins are increasingly becoming a public health concern due to the frequent contamination of various food commodities with these mycotoxins, posing potential health risks to humans. This study developed QuEChERS extraction method coupled with LC-MS/MS for simultaneous quan-tification of alternariol monomethyl ether (AME), alternariol (AOH), tentoxin (TEN), tenuazonic acid (TeA), altenuene (ALT), enniatins (ENNs) A, A1, B, and B1, and beauvericin (BEA) in tomatoes and derived tomato products. The validated method was successfully applied for a survey of 194 tomatoes and derived tomato products. Overall, one or more mycotoxins were detected in 58.8% of the samples, 100% of tomato powders, 100% of canned tomatoes, 89.6% of tomato sauces, 82.1% of ketchups, 46.7% of tomato juices, and 20% of dried tomatoes, with no mycotoxins detected in fresh tomatoes. Various mycotoxins were detected at relatively higher contamination levels in tomato powders than in other tomato products. TeA, the most predominant mycotoxin, was detected in 56.7% of the samples with an occurrence level of up to 7,985 mu g/kg. Approximately 39.2% of positive samples presented the co-occurrence of more than one mycotoxins, and AME + AOH + TeA was the most frequently detected combination. This study is the first to perform the deterministic risk assessment for children and adults on Alternaria and Fusarium mycotoxins that are present in tomatoes and derived tomato products in China. The results showed that the average and 95th percentile dietary exposures to these mycotoxins, especially to AME and AOH, in children might be higher than those in adults by a factor of approximately 2. The estimation of exposure to either Alternaria mycotoxins or Fusarium mycotoxins indicated that the presence of Alternaria and Fusarium mycotoxins in derived tomato products might be a health concern, especially among children and the populations consuming a high amount of these products. However, no firm conclusion could be drawn due to the lack of relevant in vivo toxicity data. This study serves as a useful reference for individuals and food safety authorities concerning mycotoxin contamination in food commodities.
