Sodium Metabisulfite Health Effects

Sodium metabisulfite is a commonly used food preservative and antioxidant. While it is generally recognized as safe by regulatory agencies when used in small quantities, exposure to high levels can cause health effects.

Inhalation of sodium metabisulfite dust or vapors can irritate the respiratory system, leading to symptoms such as coughing, wheezing, and shortness of breath. Long-term exposure to high levels can also lead to bronchitis and asthma.

Skin contact with sodium metabisulfite can cause irritation, redness, and even chemical burns. Eye contact can cause severe irritation and damage, potentially leading to blindness if not promptly treated.

Ingestion of large amounts of sodium metabisulfite can cause nausea, vomiting, diarrhea, and abdominal pain. In rare cases, it can also lead to anaphylaxis in individuals who are sensitive or allergic to sulfites.

Overall, while sodium metabisulfite can be safely used as a food preservative, proper handling and safety precautions should be taken to minimize the risk of adverse health effects.
