Is Sodium Metabisulfite Carcinogenic
Sodium metabisulfite (Na2S2O5) is not classified as a known or suspected carcinogen by international regulatory agencies such as the International Agency for Research on Cancer (IARC), the National Toxicology Program (NTP), or the Occupational Safety and Health Administration (OSHA). However, inhalation of sodium metabisulfite dust or fumes may cause respiratory irritation and asthma-like symptoms in sensitive individuals. Ingestion of large amounts of sodium metabisulfite may also cause gastrointestinal symptoms such as nausea, vomiting, and diarrhea. Therefore, proper handling and use of this compound are recommended to minimize potential health risks.
