What Is Sodium Nitrite?

An inorganic compound used as a preservative and color fixative in cured meats (bacon, hot dogs, deli meats, ham). It prevents growth of Clostridium botulinum, the bacterium responsible for botulism.

Mechanism of Action

Reacts with secondary amines in meat during high-temperature cooking to form N-nitrosamines, a class of compounds classified as probable human carcinogens (IARC Group 2A). The nitrite itself also reacts with hemoglobin, which is why it is regulated to prevent methemoglobinemia.

Why People Avoid Sodium Nitrite

Regulatory Status

🇺🇸 FDA

FDA-approved for use in cured meat products at regulated levels (21 CFR 172.175). Maximum 200 ppm in finished product. Required to be used with ascorbic acid or erythorbic acid to inhibit nitrosamine formation.

🇪🇺 EFSA

EFSA re-evaluated in 2017 and maintained approval with a reduced ADI of 0.07 mg/kg body weight/day (as nitrite ion). EFSA noted that combined exposure from all sources could exceed the ADI in some population groups.

Regulatory Timeline

1925 USDA approves use in meat curing
• 1970s — Nitrosamine concerns first raised
1978 FDA mandates ascorbate addition to inhibit nitrosamine formation
2015 WHO/IARC classifies processed meat as Group 1 carcinogen, citing nitrite-mediated nitrosamine formation as a mechanism
2017 EFSA re-evaluates, reduces ADI
