Why this verdict

E542 edible bone phosphate is a calcium-phosphate compound extracted from animal bones, typically cattle, used as an anti-caking agent in powdered foods and as a mineral fortifier. SANHA classifies E542 as Mushbooh. MUIS marks E542 as syubhah and lists its source plainly as an extract from animal bones. The fiqh question is the source: bone phosphate from a zabihah-slaughtered animal is halal, from a porcine source it is haram, and from non-zabihah cattle it is doubtful. The species and slaughter method are rarely declared on labels, so E542 is doubtful by default.

Food-safety note
Permitted as an anti-caking agent and mineral source in Australia and New Zealand under the Food Standards Code (Schedule 15), subject to maximum permitted levels. Regarded as safe at the levels used in food. (Source: FSANZ; Food Standards Code Schedule 15.)
