Is rennet halal?

Animal rennet from halal-slaughtered animals is halal. Animal rennet from non-halal slaughtered animals is haram (this includes most commercial animal rennet in Western countries). Microbial rennet (from fungi/bacteria) and vegetable rennet are halal. Look for 'suitable for vegetarians' labels on cheese.

The halal status of rennet varies because formulations and sourcing differ between countries and regions. A product may be halal certified in Muslim-majority countries but not in Western markets. Manufacturing processes, ingredient suppliers, and local regulations all affect whether a specific product meets halal requirements in your area.

To verify the halal status of rennet in a product, check the packaging for halal certification from a recognised body. You can also contact the manufacturer directly to ask about the source of the ingredient. The CheckMyHalal database provides information on common ingredients and their typical halal status.
