Classification, toxicity and determination method progress especially the pretreatment and limit of quantitation of beauvericin (BEA) and 4 main kinds of enniatins (ENNs) including enniatins A (ENA), enniatins A₁ (ENA₁), enniatins B (ENB) and enniatins B₁ (ENB₁) in food were introduced. The contamination levels of BEA, 4 kinds of ENNs and their co-occurrence mycotoxins in food from Spain, Morocco, Italy, Japan and some other countries were analyzed. Establishment of high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) determination method for the complex food matrix was suggested.
