Doctors' suit: KFC grilled chicken a danger

After losing its first battle against fast-food restaurants, a doctors group went back to court and accused the KFC chain of selling grilled chicken with dangerous levels of a cancer-causing chemical. In a lawsuit in San Francisco Superior Court, the Physicians Committee for Responsible Medicine accused KFC of violating California's Proposition 65, which requires businesses to warn customers if they are being exposed to substances that cause cancer or birth defects.
