Fast food giant Domino ’ s is selling ‘ Frankenfood ’ pizzas to customers while claiming to be ‘ GM-free ’ on its website . It has emerged that their ‘ thin and crispy ’ pizza bases have been made using genetically modified soya bean oil and maize flour since February . Waitrose has also been selling imported American confectionery which contains GM sugar beet and a soya derivative and Marks & Spencer has been stocking American sauces and cookies containing GM soya and corn – even though the firm has previously boasted about not using GM ingredients . Fast food giant Domino ’ s is selling ‘ Frankenfood ’ pizzas to customers while claiming to be ‘ GM-free ’ on its website . The double-dealing has been identified by GM Freeze , which is campaigning to raise awareness about how GM foods are creeping into the national diet without the knowledge and approval of consumers . The group ’ s director , Liz O ’ Neill , is now demanding an investigation to see if Domino ’ s has broken labelling laws – as firms using GM ingredients are required to label their use . She said : ‘ Domino ’ s website currently contradicts itself . If they have introduced GM ingredients to their pizza crusts then customers should be told much more clearly . ‘ People in the UK have demonstrated time and again that they don ’ t want to eat GM food and the FSA ’ s public attitudes survey recently showed concern about GM at an all-time high . ‘ Whether people are motivated by concern for declining wildlife and flourishing superweeds , for the wider ethical issues around GM farming or just their own personal choice , we all have the right to know what we are buying before we get to the till. ’ Waitrose has also been selling imported American confectionery which contains GM sugar beet and a soya derivative . Domino ’ s has confirmed that it has been using thin and crispy pizza bases with GM ingredients since the beginning of February after its usual supplier in Ireland had a factory fire which stopped production . The firm apologised for not updating its website , and confirmed that it hopes to return to using non-GM bases in September . M & S said its decision to stock GM products ‘ in no way affects our commitment to only using non-GM ingredients in M & S food ’ . And a Waitrose spokesman insisted that any GM ingredients in American chocolate stocked by the store were ‘ clearly labelled ’ . GM crops like sugar beet , corn or maize and soya have been at the centre of concerns that the associated industrial farming practices have caused serious harm to the environment . Marks & Spencer has been stocking American sauces and cookies containing GM soya and corn – even though the firm has previously boasted about not using GM ingredients . The plants have been altered through the insertion of foreign genes that create toxins to kill insects or give them immunity to spraying with powerful chemical weed killers . There is evidence from the USA that certain weeds have developed immunity to the same weed killers with the result that they are taking over many fields . At the same time , the use of sprays alongside the GM crops is thought to have caused a collapse in the population of the Monarch butterfly , which is now under threat . Critics of the technology are also concerned about the lack of independent research to show the resulting food is safe to eat . A recent Food Standards Agency ( FSA ) study found a rise in concerns about GM food . Some 24per cent listed GM as a concern , which was higher than food hygiene in the home .
