What it is and where it comes from
When a label says only "animal fat" or "animal shortening", the animal is not named. In practice it is often pork fat, beef fat or a blend. Only fat from halal-slaughtered animals is accepted by halal certifiers.
Where you find it
Biscuits, pastry, pies, frying oils, ready meals and some bread.
What to look for on the label
Avoid "animal fat" unless the product carries a halal logo. "Vegetable fat" or "vegetable oil" is halal.
This is a guide, not a fatwa. Recipes change, so check the label, look for halal certification, and ask your local imam where scholars differ.
