EFSA Concerned About Exposure to Sulfites from Food, Data Needed
The European Food Safety Authority’s (EFSA’s) recently updated risk assessment of sulfur dioxide and sulfites concludes that dietary intakes of sulfites may be a food safety concern. EFSA also found evidence of adverse health effects on the central nervous system such as a delayed response of nerve cells to stimuli, which is an early sign of nervous system dysfunction. However, gaps in toxicity data meant the extent of certain adverse health effects could not be confirmed.
Sulfites are naturally occurring, and are also added as preservatives and antioxidants to a range of foods, such as dried fruit and vegetables, potato-based products, beer and malt beverages, wine, and fruit juices. Sulfites may also be used to halt fermentation during the winemaking process.
