Q: If my child is allergic to chicken eggs, could I safely cook for him using quail eggs instead?
Dr. Sharma: People with allergy to hen’s eggs are usually also allergic to other bird eggs. So, this includes quail eggs, as well as those of turkey, duck, goose and seagull.
This is called cross-reactivity, and it occurs because of the similarity in the protein structures among these various bird eggs.
Cross-Reaction to Quail Egg
While it is possible to be allergic to one type of bird egg but not others, that is rare. It’s much more common to have cross-reactivity.
Anaphylaxis to quail egg has been reported in those with hen’s egg allergy. So the usual allergist recommendation for someone with hen’s egg allergy would be to avoid all other bird eggs.
