Ochratoxin A (OTA) is a carcinogenic and nephrotoxic mycotoxin produced by fungal species belonging to Aspergillus and Penicillium genus. OTA occurrence in foodstuffs depends on the climate during harvest and on the post-harvest storage conditions. Among known ochratoxins, OTA currently contaminates crops. Due to its prevalence and toxicity, OTA occurrence development conditions in raw cocoa beans were previously studied during post-harvest treatments. This research aimed to investigate on the biological control of OTA excretion in cocoa.
