Ochratoxin B is the non-chlorinated analogue of the much more extensively studied ochratoxin A. It is co-produced by the same species of Aspergillus and Penicillium that are associated with food spoilage. Ochratoxin B has received little focused investigation and its mode of action and potential hazards have been inferred from ochratoxin A. Ochratoxin A and B often produced by the Aspergillus species and the Penicilium species are routinely detected with rapid tests (e.g. ELISA) and reference methods (chromatography, e.g. LC-FLD or LC-MS/MS).
