Abstract: Ochratoxin A (OTA) is a secondary metabolite produced by Aspergillus ochraceus, A. carbonarius, and Penicillium spp., which may contaminate a broad variety of fruits, nuts and related products, especially fresh grapes and grape products. OTA is highly toxic, carcinogenic, extremely stable, and difficult to eliminate. Therefore, maximum limits for OTA have been set in many countries. In this review, we summarize the current knowledge on the biosynthesis of OTA, the technologies used for OTA detection in fruits, nuts and related products, and the current status of OTA contamination and propose some countermeasures to control OTA contamination. Future prospects for rapid detection as well as green and safe prevention and control of OTA are addressed. It is expected that this review will provide a theoretical basis and guidance for highly efficient analysis and effective control of OTA contamination in fruits, nuts and related products.

Key words: fruits and nuts, ochratoxin A, biosynthesis, prevention and control, determination
