I wrote here how supermarkets were selling halal chicken and lamb - chicken and lamb killed in accordance with Islamic ritual - without its being marked as halal and without customers being told. Halal chicken was being used in fast food chains, and halal food was being served in hospitals, schools, pubs and sporting venues across the UK, again without customers' knowledge.
MPs have since complained that halal food has been served at facilities at the House of Commons without their being aware.
Barnabas Aid says halal meats now make up 11 per cent of all meats sold in the UK.
"Muslims are working actively to integrate halal meat into the mainstream market and to extend it to non-Muslims. . . The spread of halal is part of a Muslim commitment to Islamic mission and the islamisation of non-Muslim societies. The imposition of sharia [Islamic] law on non-Muslims may be interpreted as an assertion of Islamic supremacy. . . Halal is being used as an underhanded way of furthering the islamisation of the country."
A portion of money spent on halal food, say Barnabas, goes to Islamic agencies, and Christians may unwittingly be funding Islamic activities.
"Many Christians are uneasy about buying halal food. . . They see such purchases as advancing the cause of global Islam, and of Islamist radicalism in particular, and as putting them implicitly under the authority of Islamic sharia.
"For this reason, while in no way objecting to the provision of halal products for Muslim consumers, they argue that these should not be forced on the non-Muslim community or sold without appropriate labelling. In addition, Christian farmers do not want to be responsible for sacrificial slaughter of animals to Allah."
A petition has been organised supporting the freedom of religious groups to access products that meet the requirements of their faith, but expressing concern about the massive growth of sharia-compliant products for everyone whatever their faith, often without consumers, parents of schoolchildren and others being informed or consulted.
It calls upon Government agencies and the food industry to label halal products clearly, expresses concern about the lack of informed choice for consumers in supermarkets and restaurants, and calls on the food industry to ensure that halal does not become the general default option in non-Muslim countries.
