In a separate development on Tuesday, Shechita UK director, Shimon Cohen, and Chanoch Kesselman of the United Orthodox Hebrew Congregation, gave evidence to the All-Party Parliamentary Group on Beef and Lamb.
Shechita UK had submitted written evidence to the group arguing that shechita was humane, and that labelling should apply to meat produced by all methods of slaughter.
The row over kosher and halal practices intensified last week after the Sun newspaper reported on Pizza Express serving only halal chicken in its restaurants. It led to widespread media criticism of the use of unlabelled halal meat in restaurants and supermarkets.
In response, Shechita UK chairman Henry Grunwald and Muslim Council of Britain deputy general secretary Dr Shuja Shafi wrote to the Telegraph to defend religious slaughter.
