Fusarium toxins are toxic and harmful secondary metabolites produced by toxigenic Fusarium spp. during infection in grains. Contamination with Fusarium toxins threatens the safety of staple grains and animal health. In recent years, with the deepening of toxin research and the development of detection technologies, modified mycotoxins with changed chemical structures and biochemical properties have been detected. These modified mycotoxins are produced during processing, or through chemical or biological reactions in plants, animals or microorganisms, and could not be identified by conventional detection. Modified toxins can be transduced through the food chain and release free toxins after animal consumption. This article reviewed the recent research progress of modified Fusarium toxins, including the modification types, natural occurrence, toxicology, which would provide references for the comprehensive assessment of the contamination risk of Fusarium toxins in grains and control strategies development.
