Curing salts, nitrites and nitrates (E250 to E252): Halal or Haram?
Halal
The salts that keep cured meat pink and safe. The salts themselves are mineral or synthetic and raise no question. The meat they cure is judged separately: a curing salt cannot make pork or an unverified slaughter acceptable.
E250 Sodium nitrite
The curing salt that keeps cured meat pink and safe.
Why it is Halal. This is the fast-acting one, the salt doing the work in most cured meat you buy.
Where you meet it. Ham, salami, sausages, cured poultry.
E251 Sodium nitrate
A curing salt that releases its effect slowly.
Why it is Halal. Mined as mineral nitrate or made synthetically. As with E250, the meat is a separate question.
Where you meet it. Dry-cured meat, some cheeses.
E252 Potassium nitrate
Saltpetre, the traditional curing salt.
Why it is Halal. Mineral or synthetic in origin, with no animal step.
Where you meet it. Dry-cured meat, hard cheese.
What to do in the shop
