Some religious leaders have recommended clearer food labelling to specify halal meat products that are sold in supermarkets and restaurants.
- Under Islamic rules, animals slaughtered using the halal method should be blessed and then killed by a single cut to the throat.
- However, the Food Standards Agency says more than 90 percent of animals used for halal meat in the UK are stunned before being killed - making them desensitised to pain.
- The RSPCA makes no distinction, in terms of animal welfare, between pre-stunned halal meat and conventionally slaughtered meat.
- It only says consumers should be told if an animal is killed without pre-stunning.
- Chains such as Pizza Express, which serves halal chicken, say their suppliers only provide pre-stunned meat.
