An Independent Prohibition in the Quran

The Quran states the same prohibition entirely independently, forbidding the flesh of swine within the same short list of dietary restrictions that also names carrion, blood and any food formally dedicated to a god other than God, a list repeated with only minor wording variation across several separate verses of the text. Islamic legal tradition treats the prohibition as essentially absolute rather than as an ordinary dietary preference among several options, permitting an exception only under genuine necessity, such as survival, where truly no other food is available at all. Because both prohibitions rest on entirely independent scriptural authority within their own respective traditions rather than one tradition simply borrowing the rule from the other, and because pork nonetheless remains a widely eaten meat across much of the rest of the world, the shared taboo has become one of the most publicly recognized religious dietary restrictions in existence, cited routinely, including by members of both communities themselves, as a marker of Jewish and Muslim identity within the food practices of wider, majority pork eating societies around them. Halal certification today extends the ancient prohibition into a modern commercial industry, requiring producers to demonstrate an entire supply chain free of pork derivatives, including gelatin, enzymes and other processing aids that might otherwise go unnoticed by a consumer simply reading a product's primary list of ingredients.
