Is There Any Evidence To Suggest That Sodium Metabisulfite Is Carcinogenic?

There is limited evidence to suggest that sodium metabisulfite may be carcinogenic. Studies conducted on animals have shown that exposure to high doses of the compound can lead to increased incidence of tumors in certain organs such as the lungs and liver. However, there are no conclusive studies on the carcinogenic effects of sodium metabisulfite in humans.

Furthermore, studies on the compound's toxicity have shown that it can cause respiratory irritation and allergic reactions in some individuals. As a result, regulatory agencies such as the United States Environmental Protection Agency (EPA) and the European Union have set limits on the use of sodium metabisulfite in food and other products.

Overall, while there is some evidence to suggest that sodium metabisulfite may have carcinogenic effects, further research is needed to fully understand its potential health risks.
