Ochratoxin C（Cat No.:R050073）is a lesser-known member of the ochratoxin family of mycotoxins produced by certain Aspergillus and Penicillium species. Structurally related to ochratoxin A, it often appears as a minor contaminant in foods like cereals, coffee, cocoa, and dried fruits. Although less extensively studied, ochratoxin C’s toxicological profile suggests potential harmful effects on kidney function and possible carcinogenicity. It can coexist with other ochratoxins and may be formed through metabolic transformations. Regulatory measures and proper storage conditions help significantly reduce ochratoxin C contamination, safeguarding public health and food safety worldwide.
