Scholarly view
Schools of law
HanafiIn this school the bone of any animal other than the pig is pure (tahir), whether or not the animal was slaughtered the Islamic way (zabiha), because life is held to be in the flesh and blood, not in the bone. Pig bone is impure, so bone phosphate made from pigs is haram.IslamQA.org — bone extract ↗SeekersGuidance — bone prayer beads ↗
Permissible
Maliki · Shafi'i · HanbaliBone from an animal not slaughtered the Islamic way takes the ruling of carrion (maytah, an animal that died without Islamic slaughter) and is impure (najis) in these schools; this is the best-known Maliki view, though a few Maliki scholars held such bone pure. Pig bone is haram, and bone from a properly slaughtered lawful animal is permitted. Undisclosed bone phosphate therefore leans towards not permitted, and only certified Halal-slaughtered bone is accepted.Islamweb — bones of dead animals ↗IslamQA.org — selling bones ↗

What to do in the shop
Look for a product that names the source, says plant-based or vegan, or carries a Halal certificate. If nothing on the packet settles it, the manufacturer can tell you, and their answer is the only thing that turns E542 from a question into an answer.
A status here describes the additive in general, and a specific product can be different. The same number can be made from plant or animal material depending on the manufacturer, and the label does not say which.
