CA becomes first state to ban restaurants from using trans fats

California is joining the health crusade against artery-clogging trans fats. Gov. Arnold Schwarzenegger signed legislation Friday that will prohibit restaurants and other "food facilities" from using oil, margarine and shortening containing trans fats. Violations could result in fines of $25 to $1,000. Food sold in their manufacturers' sealed packaging would be exempt. New York City and Philadelphia have ordinances banning trans fats, but Schwarzenegger's office says California is the first state to adopt such a law.
