赭曲霉毒素A(OA)主要由纯绿青霉、赭曲霉和碳黑曲霉产生 ,主要污染谷物、动物饲料和动物性食品 (猪肾脏、肝脏 ) ,是具有很强力的肝脏毒性和肾脏毒性 ,并有致畸、致突变和致癌作用的一种真菌毒素 ;在世界某些地区 ,该毒素被怀疑与猪真菌毒素肾病有关 ,并在流行区人血液中检出该毒素。膳食摄入OA与人类健康的关系越来越引起人们的重视 ,本文就OA产生菌、对农作物的污染、毒性和危险性分析等诸多方面进行了综述
Ochratoxin A (OA) is mainly produced by Penicillium chrysogenum, Aspergillus ochraceus, and Aspergillus niger. It mainly pollutes cereals, animal feed and animal foods (porcine kidney and liver) and has very strong liver toxicity and nephrotoxicity. And a mycotoxin that is teratogenic, mutagenic and carcinogenic. In some parts of the world, the toxin is suspected to be associated with porcine mycosis nephropathy and detected in human blood in endemic areas. The relationship between dietary intake of OA and human health is attracting more and more attention. In this paper, many aspects such as OA-producing bacteria, contamination of crops, toxicity and risk analysis are reviewed
