Sodium nitrate works by inhibiting the growth of harmful bacteria, such as Clostridium botulinum, which can cause food spoilage and foodborne illness.

Sodium nitrate breaks down into nitrite, which reacts with the meat to inhibit the growth of harmful bacteria and extend the shelf life of the food product.
Similarities: Both nitrate and nitrite ions are composed of nitrogen and oxygen atoms and have a negative charge. They are also used in fertilizers and preservatives in food. Differences: The nitrate ion has three oxygen atoms, while the nitrite ion has two. Nitrate is more stable and less toxic compared to nitrite, which can be harmful in high concentrations. Nitrate is often used in agriculture, while nitrite is commonly used as a food preservative.
Nitrate is added to some products as preservative. Eating fresh food is an option to avoid prervatives. However unfresh food without any preservative is itself a health risk. Some say nitrates are a health risk in themselves, others disagree.
