The Washington-based Physicians Committee for Responsible Medicine (PCRM) filed a lawsuit today in California against McDonald's, Burger King, Chick-fil-A, Chili's, Applebee's, Outback Steakhouse and TGI Friday's, saying that every sample tested of grilled chicken from every chain "tested positive for a dangerous carcinogenic compound called PhIP" during analysis at an independent laboratory. A staff attorney with the PCRM said the restaurants are in violation of a 1986 California law that requires them to give a "clear and reasonable warning" about carcinogens in their food. The law carries a fine of 2,500 dollars per violation per day.
