Halal ingredient guide

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

Short answerCheese made with microbial or vegetable rennet is halal. Cheese made with animal rennet is halal only if the animal was slaughtered Islamically — though some scholars accept it regardless. When the label just says “enzymes”, the source is unknown, so the cheese is doubtful.

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

Microbial enzymes, microbial rennet, vegetable rennet, non-animal rennetHalal
Enzymes, rennet (no source)Mushbooh
Animal rennet, calf rennetMushbooh scholars differ
Pepsin (often from pigs), lipase (often animal)Mushbooh
Halal-certified cheeseHalal

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.

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.
