When Food Is A Danger

In the meantime, here's what experts recommend for people with food allergies:

· Always read food labels. Formulations of products can change without notice.

"Don't assume that because it was safe last month, that it will be safe this month," says Anne Muñoz-Furlong, founder and head of the Food Allergy and Anaphylaxis Network.

· Look beyond traditional food products.

Pet food and bath products can often contain food allergens. These and other products can be especially dangerous for toddlers and young children who might pick up food left out for a pet or react to bath products.

· When in doubt, ask. Not sure about a product's ingredients? Call the manufacturer.

"Don't just ask what it contains," Muñoz-Furlong says. "Ask specifically if it contains the ingredient or ingredients that cause your allergy."
