The governor acknowledges scientific data largely shows no known health problems caused by genetically-engineered foods. But he also says some consumers want to know exactly what's in their food, so he has to give it more thought.

The Yes on I-522 campaign has received about $5.1 million in contributions. The NO on I-522 campaign has just over $17 million -- including from five major food corporations.

Supporters claim consumers have a right to know if their food contains genetically-engineered ingredients. Opponents say it would raise food prices and cost consumers.  Some reports put the annual increase at about $450 for a typical family of four.

While the Yes campaign claims it wouldn't cost a dime, the state budget office found implementing the program, as written, would cost about $3.4 million dollars over six years.  Just how directly that would affect consumers remains to be seen.
