呕吐毒素的污染状况及对动物机体的毒性研究进展

Progress on the Pollution Status of Deoxynivalenol and Its Toxicity to Animal Bodies

呕吐毒素又称脱氧雪腐镰刀菌烯醇(deoxynivalenol,DON),主要是由禾谷镰刀菌产生的一种有毒次级代谢物,主要存在于霉变的玉米、小麦、大麦等谷物类作物及其制品中。因其理化性质稳定,易与其他霉菌毒素共同污染农作物,且具有广泛毒性,给畜牧业健康养殖带来巨大的经济损失。论文就呕吐毒素的理化性质、污染状况、限量标准及其对动物机体的毒性作用进行综述,为更好地防控呕吐毒素对动物健康的危害提供理论参考。

Vomitoxin,also known as deoxynivalenol(DON),is a toxic secondary metabolite produced by Fusarium graminearum.It mainly exists in moldy corn,wheat,barley and other cereal crops and their products.Due to its stable physicochemical properties,it is prone to co-contaminate crops with other fungal toxins,and has widespread toxicity,causing huge economic losses to the healthy breeding of animal husbandry.This article reviews the physical and chemical properties,pollution status,limit standards,and toxic effects of deoxynivalenol on animal bodies,It can provid theoretical reference for better prevention and control of the harm of deoxynivalenol to animal health.
