Ferrero, the maker of Nutella, has hit back at claims that palm oil used in their hazelnut and chocolate spreads could cause cancer. In May, the European Food Standards Authority warned that the contaminants found in the oil’s edible form are carcinogenic. It warned that even moderate consumption of the substances represented a risk to children and said that, due to a lack of definitive data, no level could be considered safe. Palm oil is found in hundreds of household name food brands including Cadbury’s chocolate, Clover and even Ben & Jerry’s, but Nutella has so far faced the brunt of a consumer backlash. Sales fell by three per cent in the year to August 2016 as consumers ditched the product for palm-oil free alternatives. Coop, the country’s biggest supermarket chain removed 200 products containing palm oil, though not Nutella, from its shelves in May as a precaution. In response, Ferrero has launched an advertising campaign in an attempt to reassure customers that its products are totally safe. Ferrero insists that the decision to keep palm oil in Nutella, despite safety fears, is about quality, not cost. The substance is used to give the spread its smooth texture which it says can’t be achieved by using other oils. “Making Nutella without palm oil would produce an inferior substitute for the real product, it would be a step backward,” Ferrero's purchasing manager Vincenzo Tapella told Reuters.
