The following is an edited excerpt.
Last month three U.K. supermarkets admitted publicly that it was impossible to guarantee that the feed fed to the poultry and fresh meat they sell did not contain genetically modified (GM) soya meal.
Tesco, the U.K.’s No. 1 and one of the world’s biggest supermarkets, had always guaranteed that its own-label fresh and frozen poultry and eggs were only fed non-GM feed. However, Tesco group technical director, Tim Smith, said the company was dropping this pledge. “We could not continue with a promise we cannot be sure it is possible to keep.”
