What the Rule Is

Sodium nitrate (E251) and the related sodium nitrite (E250) are curing salts used in bacon, ham, and cured sausages to prevent Clostridium botulinum growth and fix the pink cured colour. In United States, Sodium Nitrate is regulated under FDCA & FSMA as a food preservative. USDA regulates nitrates in cured meats (9 CFR 424.22). Maximum use levels apply. Must be declared in ingredient list as "sodium nitrate". Encapsulated forms must still be declared. Some "uncured" meats use celery juice as a nitrate source — if marketed as "no added nitrates", cannot contain direct nitrate additives.
