DH recently suspected that he may have become allergic to duck eggs after having sudden severe vomiting after eating them on two occasions recently. He has since avoided having them in semi-cooked forms like scrambled or fried eggs, but seems to be OK when they're cooked in a cake.
On Sunday I made a lemon meringue pie and without thinking put in 1 duck egg (plus a couple of chook eggs). Within 10 minutes he felt as though his throat was tight, had tingling lips and was vomiting.
Does this sound like an allergy and is it possible to be allergic to one form of eggs specifically and to be able to eat them when cooked very well, but not semi-cooked? Is this likely to develop into full-blown anaphylaxis? This could be a problem as we keep ducks...
TIA
