Tips for Life With a Seafood Allergy

If you’re allergic to one kind of seafood, your doctor may have told you to avoid others. Here’s what to look out for.

These foods may contain anchovies:

Worcestershire sauce

Barbecue sauces made with Worcestershire

Caesar salad and Caesar dressing

Caponata (Sicilian eggplant relish)

Other foods that have seafood:

Caviar and fish roe (fish eggs)

Artificial fish like surimi, an imitation crabmeat sometimes used in sushi

Fish sauce, oils, and gelatin

Certain brands of eggs,

yogurt

, juices, milk, and soy beverages fortified with omega-3 fatty acids.

Stay out of seafood restaurants. Even if you order beef, bits of seafood from a shared spatula, cooking oil, or grill can get in your food.

In any restaurant, let your server know about your

allergy

and ask that the kitchen staff use separate utensils and work surfaces to make your food. Cross-contact can happen anywhere that uses a lot of fish or shellfish ingredients.

Don't shop for or cook seafood. Let someone else do it. You may have a reaction just from touching it or being in an area where someone is cooking it.

Ask your doctor if any fish or shellfish is safe to eat. Don't try out any kinds on your own, though. That could cause severe allergic reactions.

Ask your doctor whether it’s safe for you to take fish oil supplements. You can also find those good-for-you omega-3 fatty acids in other places. Leafy green

vegetables

, walnuts, flaxseed oil, soy oil,

canola oil

and microalgae (

spirulina

) are good options.

Read labels. Other foods -- as well as lotions, cosmetics, and medicine -- may have fish in them.
