In plain words: Nitrosamines are compounds that can form in cured and processed meats. This entry collects published research about nitrosamine intake from processed meat. For the curing salts themselves, see our sodium nitrite and nitrate guide.

Published research: what individual studies found

These are findings from individual published studies and food-safety agency opinions, credited to each paper. Each one is labeled by type of evidence. They do not change any verdict, evidence grade or score on this site.

Evidence type: Cross-sectional dietary intake + margin-of-exposure risk assessment · Study found no effect

• In a survey-based risk estimate for 420 medical staff in Egypt, the researchers calculated that nitrosamine intake from processed meat indicated 'a low level of concern for carcinogenic risk' (margin of exposure ≥ 17,000). This is an estimate for one group, based on reported diets. It is not a finding about processed meat in general and may not apply elsewhere.
