What is E250?
E250 is Sodium Nitrite — a curing salt that keeps bacon and ham pink and prevents botulism — but linked to bowel cancer risk in processed meat.
What is E250 (Sodium Nitrite)?
E250 is the E-number for sodium nitrite, one of the preservatives group of food additives (E200–E299). Additives in this group prevent spoilage by stopping the growth of bacteria, moulds and yeasts. A synthetic curing salt. Sodium nitrite prevents deadly botulism in cured meats, but the WHO classifies processed meat as a Group 1 carcinogen partly because nitrites can form nitrosamines during cooking. Like every E-number, E250 has been evaluated and authorised for use in food in the European Union — the 'E' literally stands for Europe, and a number is only granted after a safety assessment. That authorisation doesn't mean every additive suits every diet or that all concerns are settled, which is why we break down the safety, vegan, vegetarian and halal status of E250 in detail below.

E250 is approved for use in the EU, UK and US at regulated levels, but some concerns or conditions apply. Nitrites and nitrates in processed meat can form nitrosamines, and the WHO classifies processed meat as carcinogenic to humans — the main reason health bodies advise limiting cured meats. For most people, normal dietary exposure to E250 is not considered harmful.
