Nitrite

Nitrite is a chemical compound formed when bacteria convert nitrate, a naturally occurring substance in soil and water, into nitrite. In food, particularly processed meats, nitrites are used as preservatives to prevent spoilage and maintain color. While nitrites themselves are relatively harmless, they can react with other substances in the body to form compounds that may be linked to health concerns if consumed in large amounts. Monitoring and controlling nitrite levels is important to ensure safety in food and water supplies.
