California’s state attorney general’s office announced that four food manufacturers―H.J. Heinz Co., Frito-Lay, Kettle Foods Inc., and Lance Inc.― agreed to reduce levels of acrylamide, a possible carcinogen, in their potato chip and french fry products. California sued the companies in 2005, alleging they violated California's Proposition 65, which requires that companies post warning labels on products with carcinogens. The companies agreed to pay a combined $3 million in fines and reduce the levels of acrylamide in their products over three years.
