The European Food Safety Authority (EFSA) has launched an open consultation on its scientific opinion regarding public health risks related to the presence of Ochratoxin A (OTA) in food. OTA is a mycotoxin naturally produced by fungi such as the Penicillium and Aspergillus species.
OTA is found in a variety of foods including grains and grain products, preserved meats, fresh and dried fruits. It is also found in breast milk.
EFSA previously assessed public health risks related to OTA in food in 2006. Experts concluded that OTA accumulates in the kidney and is particularly toxic to this organ. At high doses, OTA also causes kidney tumours in rats. EFSA set a tolerable weekly intake (TWI) of 120 nanograms per kilogram of body weight. More information has since become available suggesting that OTA may be genotoxic and carcinogenic. In such cases, EFSA experts calculate a margin of exposure (MOE) for consumers. In general, the higher the MOE, the lower the level of concern for consumers. The estimated MOE for OTA is below 10,000 across most consumer groups, suggesting a possible health concern.
Interested parties are invited to submit written comments to EFSA's Panel on Contaminants in the Food Chain (CONTAM) by 24 January 2020.
