In 1983, scientists created the first genetically modified plant. Fast forward a mere 29 years later and approximately 80% of all packaged food in the U.S. contains genetically engineered (GE) ingredients. But there’s no way for you to tell--producers aren’t required to use any labeling that indicates the use of GE crops.
That may soon change in California, where Proposition 37 (AKA the California Right to Know Genetically Engineered Food Act) will be placed on voter ballots in the upcoming November election. If passed, the proposition will require most foods containing GE ingredients (with the exception of alcoholic beverages, dairy, meat, and poultry) to come with special labeling.
