E250
Sodium nitrite
Preservative and colour fixer, cured meats
What it is. A curing salt that keeps cured and processed meats pink and stops the growth of the bacteria behind botulism.
Why it is used. Used in bacon, ham, salami and hot dogs for preservation, safety and colour.
What the evidence says. The concern is not the additive in isolation but processed meat as a whole, which the WHO's cancer agency IARC classes as Group 1, meaning there is sufficient evidence it causes colorectal cancer. Nitrite can form nitrosamines during curing and cooking, and those are the likely culprit. Risk rises with how much processed meat you eat over time.
Permitted with strict maximum levels. The EU cut the allowed limits further from 2023 to reduce nitrosamine formation.
Assessed against IARC, EFSA, UK FSA. Full entry for E250

Names and jobs come from the register of additives permitted in Great Britain, which we have not finished transcribing: a code shown without a name is a gap in our coverage, not a finding that it is unapproved. Naming one is not grading it either. Full detail appears only where we have an assessment against a named authority, so all of this describes our coverage rather than these additives. Most are common and low concern.
