House votes to dump state food safety laws, San Francisco Chronicle, March 9, 2006
Prop 65 was the Safe Drinking Water and Toxic Enforcement Act of 1986. In addition to product labels, it's also responsible for all those signs warning you of cancer and birth defects. (At bars, in garages, paint shops, etc.)
Then I would agree with the comments regarding ditching Prop 65. Those signs would make it impossible for a woman to maintain a job if she actually paid attention to them.
