Class action suits filed in federal courts in New York and California allege that ConAgra Foods is violating state consumer protection and business practices laws by claiming that its Wesson cooking oils are “100 percent natural.” The claim is misleading, the complaints argue, because the oils come from “unnatural” biotech corn, canola and soybeans.

The lawyers asked the courts to find that the labelling claims are misleading and award an undetermined amount of money to their clients and all other consumers who bought the oils, believing that they were “natural” and not derived from genetically modified crops.

The suit contends that the oils are not 100 percent natural, citing a definition by the World Health Organization of GMOs as “organisms in which the genetic material has been altered in a way that does not occur naturally.” It alleges that the claims violate California and New York false advertising and unfair competition laws and business codes.
