Cereal makers Kellogg and Sanitarium have stopped paying halal certification fees which indicated that a food is approved for consumption under Islamic religious rules.
They were previously paying fees to have their products certified by an Islamic business to indicate it was halal food.
Kellogg has denied it changed its halal policies and removed the branding from Corn Flakes and Special K as a result of public pressure, according to Seven News.
The company said the products were "inherently halal", so it chose not to renew its certification.
WeetBix producer Sanitarium said it had never needed to use halal or kosher certification symbols on Australian and New Zealand products, but was believed to have paid fees to export its products to 35 other nations.
Earlier this year, One Nation Senator Pauline Hanson urged Australians to stop buying halal-certified products, which she said were “financially supporting the Islamisation of Australia”.
Sunrise guest Prue MacSween said she didn’t think Australia’s meat manufacturers would follow suit any time soon.
