She said about three-quarters of the company’s products contained ingredients derived from corn, canola, soybeans or sugar beets, the four largest genetically engineered crops. The change in labeling is expected to take 12 to 18 months.
Other companies have reformulated a handful of products to replace such ingredients. General Mills now produces non-GMO Cheerios, and others have put labels on some products verifying that they contain no genetically engineered components, like Tropicana juices.
But none have gone as far as Campbell, whose move is reminiscent of that by Whole Foods Markets, which almost three years ago created an uproar when it announced that, as of 2018, it would require all products sold in its stores to have labels disclosing the presence of ingredients from genetically altered crops.
