Could ochratoxin A in food commodities be the cause of chronic kidney disease in Sri Lanka?

Ochratoxin A (OA) is a naturally occurring mycotoxin with nephrotoxic properties that can contaminate plant food products. OA concentrations were assessed in commonly consumed food items in the North Central Province of Sri Lanka, where chronic kidney disease is diagnosed at epidemic proportions. Ninety-eight randomly selected food samples were analysed. Mycotoxin was detected in the extract by using a MycoMonitor Ochratoxin A ELISA assay kit (Helica Biosystems Inc., USA). The levels of OA found in these food commodities were below the recommended statutory maximum limit and are unlikely to be a potential risk factor for nephropathy in the North Central Province of Sri Lanka.
