A total of 470 edible vegetable oil samples including peanut, soybean, rapeseed, sesame seed, corn, blend, and others collected from eight provinces China were analyzed for the concentrations beauvericin (BEA), enniatin (ENA), A1 (ENA1), B (ENB), B1 (ENB1) by ultraperformance liquid chromatography/electrospray ionization tandem mass spectrometry (UPLC/ESI-MS/MS). Concentrations BEA, ENB, ENB1 (average = 5.59 μg/kg, 5.16 4.61 μg/kg) in all positive higher than those ENA ENA1 0.85 μg/kg 1.88 μg/kg). Frequencies BEA ENNs 50% with exception (36.6%, 172/470). Levels varied based on their sample types geographical distributions (Kruskal–Wallis test, p < 0.05). The soybean peanut found to be more easily contaminated other samples. obtained Heilongjiang, Shandong Guizhou provinces. Besides, frequencies mycotoxin co-contaminations high co-contamination also types. BEA-ENA-ENA1-ENB-ENB1 was most commonly toxin combination type, almost one third (30%, 141/470). Overall, these results indicate that co-occurrence Chinese is highly common, it vital monitor them, both simultaneously a widespread level.
