Is cheese halal?
Milk is halal, so why is cheese a question? Because most cheese is made with rennet — an enzyme that can come from an animal’s stomach.
Updated October 18, 2026
Why rennet matters
Rennet is the enzyme that turns milk into cheese. Traditionally it comes from the stomach of young calves, which raises the question of how the animal was slaughtered. Today, much cheese — especially in the US — is made with microbial rennet or fermentation-produced chymosin instead, which involve no animal.
Reading cheese labels
| Label says | Status |
|---|---|
| Microbial enzymes, microbial rennet, vegetable rennet, non-animal rennet | Halal |
| Enzymes, rennet (no source) | Mushbooh |
| Animal rennet, calf rennet | Mushbooh scholars differ |
| Pepsin (often from pigs), lipase (often animal) | Mushbooh |
| Halal-certified cheese | Halal |
A difference of opinion: Imam Abu Hanifa held that rennet taken even from an animal not slaughtered Islamically is permissible, and many Hanafi scholars follow this. Most other scholars and halal certifiers require microbial, vegetable or halal-slaughtered rennet.
Other things to check in cheese products
- Wine or beer in some flavored cheeses and fondue.
- Lipase — used in Parmesan, Romano and provolone for flavor, often from animals.
- Bacon or pepperoni in cheese spreads and snack mixes.
How Halal Pal checks cheese
The halal scanner marks plain “enzymes”, “rennet”, pepsin and lipase as Mushbooh, while “microbial”, “vegetable” or “non-animal” enzymes and rennet aren’t flagged. Tap any flagged ingredient in the app to see why.
Frequently asked questions
Is mozzarella halal?
It depends on the rennet. Mozzarella made with microbial or vegetable rennet is halal; with animal rennet or unspecified “enzymes”, it’s doubtful unless certified.
Is cheese with enzymes halal?
“Enzymes” alone doesn’t say whether they’re animal or microbial, so it’s considered doubtful. “Microbial enzymes” are halal.
Is Parmesan halal?
Traditional Parmigiano-Reggiano is made with calf rennet, so it’s only halal by the view that accepts animal rennet. Some Parmesan-style cheeses use microbial rennet — check the label.
