Chicken or the Egg?

A 30 year old adult presents with what he thinks is asthma. He used to think he was allergic to chicken, but has been eating chicken okay. He gets short of breath and wheezy when he encounters bird feathers and eggs.

Challenge: Believe it or not, this syndrome has a name - what is it? What is the causative factor?

Is this some sort of cross reaction reaction

I recall a syndrome called bird-egg syndrome.
Can you explain what it is about?

good memory!
Chicken or the Egg?

This is bird-egg syndrome, an allergy to alpha livetin, also known as chicken serum albumin. It is thought to be inactivated by cooking.
