Sodium nitrite

What this is

Sodium nitrite is a salt used as a preservative and color fixative in processed meats like bacon, hot dogs, and deli ham. It is highly effective at preventing the growth of dangerous bacteria, including those that cause botulism, a serious form of food poisoning. It also gives cured meats their characteristic pink color and savory flavor. However, its use is controversial. Under certain conditions, such as high-heat cooking or in the stomach, nitrites can form compounds called nitrosamines, which are linked to an increased risk of certain cancers. For this reason, health organizations recommend limiting consumption of processed meats.
