Sodium nitrite prevents the growth of bacteria including clostridium botulinum, the type that causes botulisim. Sodium nitrite is commonly used in cured meats and in processed foods. Since the color is pinkish, it is often called "pink salt" by those who create sausages, cured meats and other charcuterie items. Sodium nitrite gives food a slight pink color when it is raw and long after it is cooked and when it is raw. This characteristic is useful when finding products that contain sodium nitrite.

According to a study from Oregon State University, raisins that were used in processing dried meat jerky prohibited a strain of the botulism bacteria from forming by reducing the Ph levels in the processed meat. Salt is also used as a preservative.
