Produced by processing animal bones into a phosphate. The animal species and slaughter method are usually not identified.
E542 is animal-derived, so it is halal only if it comes from a halal-slaughtered, permissible animal. Because the source is usually unspecified, it is treated as doubtful. Mineral phosphates such as calcium phosphate (E341) are a halal alternative that manufacturers can use instead.
