What Are The Health Risks Associated With Sodium Metabisulfite?

Sodium metabisulfite is a chemical compound commonly used as a preservative, antioxidant, and disinfectant in various industries, including food and beverage, pharmaceuticals, and water treatment. However, it can also pose health risks to humans if ingested, inhaled, or exposed to the skin or eyes.

When ingested, sodium metabisulfite can cause adverse reactions ranging from mild to severe, depending on the amount consumed and individual sensitivity. Symptoms may include nausea, vomiting, abdominal pain, diarrhea, headache, dizziness, and difficulty breathing. In rare cases, it can trigger a life-threatening allergic reaction called anaphylaxis, especially in people with a history of sulfite sensitivity.

When inhaled, sodium metabisulfite can irritate the respiratory system, causing coughing, wheezing, shortness of breath, and asthma-like symptoms. Prolonged exposure to high concentrations may lead to chronic bronchitis and other respiratory problems.

When exposed to the skin or eyes, sodium metabisulfite can cause irritation, redness, itching, and chemical burns. In severe cases, it may result in permanent damage and scarring.

To prevent these health risks, it's essential to handle and use sodium metabisulfite safely, following proper storage, handling, and disposal procedures. It's also essential to read the product label and follow any precautionary measures and warnings provided by the manufacturer.
