A third carcinogen, not recognized by the Campaign for Safe Cosmetics, is nitrosamine, also of quaterniums, besides other precursors.
Federally funded research into the nitrosamine levels of leading smokeless brands places Star's Ariva and Stonewall brands at the top of the least-harmful list.
Respectively, the brands carry 0.19 and 0.28 nitrosamine part per million, compared with 3.1 for General Snus, according to articles published in a public-health journal called Nicotine & Tobacco Research in 2008 and 2006.

In the case of your sausages, I would assume that they are cured and not cooked, so the nitrosamine content would be pretty low.
