Is Sodium Nitrite (E250) halal and vegan?

A curing salt and preservative that keeps cured meats pink and prevents botulism.

Is E250 halal?

The additive itself is a synthetic salt and is halal — but it is mostly used in cured meats, so check the meat is halal (e.g. not pork).

Is E250 vegan?

The additive is not animal-derived, but products with it are almost always meat, so the overall product is rarely vegan.

Is E250 safe? Health effects

Sodium nitrite is approved in the EU, US and Japan within strict limits. The concern is that, when cured meats are cooked at high heat, it can form nitrosamines — compounds linked to bowel cancer. In 2015 the WHO's IARC classified processed meat as a group 1 carcinogen. Regulators cap how much may be added, and many brands now offer lower-nitrite or nitrite-free curing. It is regular processed-meat intake, not one product, that matters most.

Where you'll find it

Bacon, ham, hot dogs, salami and other cured meats.
