Food labels will soon have to disclose in plain language whether the products contain peanuts, shellfish, eggs or other ingredients that could sicken people with food allergies. A federal law that takes effect Jan. 1 requires food labels to list ingredients made from proteins derived from any of the eight major allergenic foods: milk, eggs, fish, crustaceans, wheat, tree nuts, soybeans and peanuts. The Food and Drug Administration says they account for 90 percent of all food allergies.
