text: You should watch out for shellfish, i.e. lobster, crab, mussels, and other seafood like squid, calamari, eel.  Seafood allergies can be life-threatening and tend to get worse with repeated exposure. I carry an epi-pen and have to have another person serve my food at buffets that have seafood. I avoid shaking hands with people if at an event where seafood is served.  The food allgergy and anaphalaxis network website has excellent resource and information including cards that you can carry with you when you go to dinner to pass on to the chef about your allergy.
