I do have shellfish allergy since when I was 12 years old, but it is not severe as other. Most people should avoid all shellfish. But some are allergic to some types of shellfish and not others. Be careful if you have severe shellfish allergy because by just breathing the fumes of cooking shellfish may trigger an allergic reaction. For your safety, I got some precautions when eating away from home: avoid seafood restaurants. It is likely that shellfish may come in contact with foods your child or even you can safety eat. Avoid fried foods because many restaurants cook chicken, French fries and shrimp in the same oil, same with the grilled foods. Avoid hotdogs and deli meats, which may contain traces of shellfish. Carry a “chef card”. You can make your own card or print one from a website on the internet. This personalized card explains your child’s food allergy to restaurant workers.
