Shareholders of US food group General Mills showed strong support this week for the company's decision to use genetically-modified ingredients in Big G cereals and other products. A proposal asking the cereal and snacks maker not to use gene-altered ingredients until long-term testing shows they are not harmful to humans, animals and the environment was defeated by shareholders by a margin of more than 21-to-1. The proposal also had asked that General Mills, in the interim, label and identify products that may contain genetically engineered ingredients.
