Faith leaders have called for clearer packaging after it emerged some meat is sold in the UK which could qualify as halal but is not labelled as such.
Five leading UK supermarkets have defended selling such meat.
Retailers say the animals are stunned before slaughter and the only difference from standard meat is that they are blessed as they are killed.
The government said it wanted people to be able to make informed choices.
