Description: Under certain conditions Aspergillus, Penicillium can produce and release secondary metabolites in feed type: Ochratoxin A (OTA). Ochratoxin A (OTA) has been shown to be highly nephrotoxic compounds, hepatotoxic and teratogenic. Ochratoxin affect animal health and can be found in animal products (meat, eggs, milk) presenting a potential risk to human health. Strategies to control OTA in feed and food requires early identification and removal of contaminated products in the food chain.Toxicity of mycotoxins depends on their source and dose, duration of exposure and composition. This paper aims to address this type OTA mycotoxins in feedingstuffs and possible risk you may present it on animals and man
