Generally halal
E250 (Sodium nitrite) is a manufactured curing salt that is halal in itself — but it is commonly used to cure meats, so the meat it is used on must itself be halal.
Sodium nitrite is a chemically-manufactured salt used to preserve and cure meats, fix their pink colour and protect against bacteria such as Clostridium botulinum. The additive itself has no animal origin.
Produced industrially by chemical processes (e.g. reaction of nitrogen oxides with sodium hydroxide/carbonate). No animal-derived raw material.
The additive on its own is a mineral/chemical salt with no prohibited origin, so it is halal as an ingredient. The important caveat is context: E250 is most often found in cured meats (bacon, ham, sausages, luncheon meat). The additive does not make those meats halal — the meat itself must come from a halal-slaughtered, permissible animal. So a product's halal status depends on the meat, not on the nitrite.
It may be found in — this does not mean every product below contains it.

In Singapore, verify the finished meat product on the MUIS HalalSG register. The presence of E250 tells you nothing about the meat's halal status — always confirm the meat/product certification.

Halal does not automatically mean healthy, and a health concern does not automatically make an ingredient haram.
Halal does not automatically mean healthy. Nitrites in cured meats can form nitrosamines under certain conditions, and health authorities advise moderating processed-meat intake; the International Agency for Research on Cancer classifies processed meat as a Group 1 carcinogen. This is a health/safety consideration and is separate from halal status.
Permitted as a preservative/curing agent within strict maximum limits in the EU, UK and many other markets, because of its role in preventing botulism.
The additive itself is a chemical curing salt and is halal. But it is usually used on meat — and the meat must itself be halal for the product to be halal.
No. A permissible curing salt does not make a non-halal meat acceptable. The meat must come from a halal source.
No. It is manufactured chemically with no animal-derived raw material.
Check the finished product on the MUIS HalalSG register or with the manufacturer — the meat's certification is what matters.
Humble Halal methodology: we classify additives by their common origin, not by any specific product. A generally-halal ingredient does not make a finished product halal-certified.
