N-nitrosaminer er en gruppe organiske forbindelser, hvorav mange har karsinogene (kreftfremkallende) egenskaper. Etter at det i 1956 ble påvist at N-nitrosodimetylamin (CH3)2N2O hadde karsinogene virkninger, har det foregått omfattende forskning på området. I 1964 oppdaget man at sauer fôret med sildemel fremstilt av nitrittbehandlet sild fikk leverskader som skyldtes N-nitrosodimetylamin.
