Processed meat (ham, bacon, hot dogs, deli meats, sausages) is IARC Group 1 (carcinogenic to humans — colorectal cancer).
What is this product?
Processed meat (ham, bacon, hot dogs, deli meats, sausages) is IARC Group 1 (carcinogenic to humans — colorectal cancer). Nitrosamines (NDMA, NDEA) form when nitrite preservatives react with secondary amines during cooking, especially high-heat cooking (frying, grilling). NDMA and NDEA are each IARC Group 2A (probably carcinogenic to humans; Monograph Vol 17), distinct from the Group 1 classification of processed meat itself. Sodium nitrite (E250): used for color, flavor, and Clostridium botulinum prevention. 'No nitrate/nitrite added' products use celery powder — a natural nitrate source that converts to nitrite identically. USDA: celery powder-cured products contain equivalent or higher nitrite levels than conventionally cured. 50g processed meat/day increases colorectal cancer risk 18% (IARC).
