Nitrosamines in Processed Food and Beer (NDMA) — food safety profile

Moderate risk

N-nitrosamines (NDMA, NDEA, NPIP) form in processed meats during curing/smoking and in beer during malt kilning.

What is this product?

N-nitrosamines (NDMA, NDEA, NPIP) form in processed meats during curing/smoking and in beer during malt kilning. NDMA is an IARC Group 2A probable carcinogen. German beer industry reformed kilning process (1970s-80s) after NDMA discovery — reducing beer NDMA by 90%+. Processed meats remain the primary dietary NDMA source. Vitamin C (ascorbic acid) inhibits nitrosamine formation — now added to cured meats (but not all brands).
