Can I eat shrimp and other seafood?

The basic rule

The Quran makes food from the sea lawful:

When asked about the sea, the Prophet Muhammad ﷺ said: "Its water is pure and its dead are lawful" (Sunan Abu Dawud 83, Jami' at-Tirmidhi 69). That's why fish and seafood don't need to be slaughtered, unlike chicken or beef. Fish from any supermarket is halal. Canned tuna and frozen fish are fine too, though it's worth a quick look at the ingredients for added flavorings or wine.

The Hanafi view

The Hanafi school, followed by many Muslims of South Asian, Turkish and Central Asian background, only fully permits fish. Crab, lobster, mussels, clams and oysters are not allowed in this school. Shrimp is debated within the school, and many Hanafi scholars allow it as a kind of fish.

If you follow the Hanafi school, stick to fish and, for most, shrimp. If you follow the majority, enjoy the whole menu.

Hidden issues at restaurants

The seafood itself is rarely the problem. What's cooked with it can be:

• Wine or beer in sauces, like mussels in white wine or beer-battered fish. See Is vanilla extract haram because it has alcohol?
• Bacon wrapped around scallops or shrimp, or crumbled into chowder.
• Shared fryers used for pork or non-halal chicken. Scholars differ on this, so ask if it matters to you.
• Sushi rice is often seasoned with mirin, a sweet rice wine. Ask, or choose places that don't use it.

What about other sea creatures?

Squid, octopus and eel are treated like other seafood: halal for the majority, not for the Hanafi school. Animals that live both on land and in water, like frogs and crocodiles, are a separate discussion, and most scholars say to avoid them.
