Allergic to eggs, anyone tried ducks eggs?

Interesting read.
The reason I was asking, is because my son is allergic to eggs, chicken and feathers. The whole bird.

But 36 hours ago I gave him turkey, Ive been avoiding it, thought it was obvious being poultry but doctors keep asking if he can have turkey and I need to be able to answer them as they are talking about exploratory surgery very soon because he's allergic to 30 foods and counting.

So far, he has had no reaction from the turkey. I just really need him to do a poo to prove this, but so far, so good.

Made me wonder if he would be ok with turkey eggs (cooked) do people use turkey eggs??

Then I wondered if he'd be ok with duck eggs.

As I said, I have absolutely no intention of testing duck eggs on my son. Thats not to say a SPT wouldnt be able to test next time his annual one is due.

Very good point about being ok with breast milk but not cows milk, ds certainly thrives on my milk. Also super allergic to goats milk.

But if he can eat pork (allergic to beef and lamb) then maybe hes ok with pig or turkey milk? <barf>

Thank you louisianablue2000 - interesting stuff indeed and pretty much what I thought ie yes they are different in their protein structures but probably not different enough!

My dh is very allergic to duck eggs but is fine with hen eggs. So, yes it is theoretically possible but it would be risky to try!

Hi, I've got a PhD in immunology and still use that knowledge in my current job (I work in the pharmaceutical industry) so just wanted to give you a short explanation of the science. My DS is also allergic to eggs and milk, but thankfully not as severely as yours.

Hen and Duck eggs both contain a selection of proteins, and there will be small differences between the sequence and structures of those proteins in each species. Without trying (or, more safely, doing blood tests) you can't know if your son is reacting to a protein (or short sequence of a protein) that is the same or different in duck and hen. I'm sure there will be some lucky people who react to one but not the other but my expert view is that most people will be reacting to more than one epitope (that's the technical term for the short sequence of protein that an antibody reacts to) and so are likely to react to both hen and duck. The two species are very closely related.

But it is a reasonable question, after all most people with a cows milk protein allergy don't react to human milk, there are differences in the sequence of casein that must be sufficient to cause an allergy to one but not the other. Of course, we have a evolutionary driver in that historically anyone who had an allergy to human casein wouldn't live long enough to reproduce. That evolutionary drive doesn't exist to encourage tolerance of one type of egg but not another.

don't really know of anyone who has tried it, as most egg allergic folks I know would avoid it.

Thanks. But I wasnt posting to say I had any intention of feeding duck eggs to my son.

I was wondering if anyone on here has a child allergic to hen eggs that was ok with duck eggs.

in that case I would avoid

He is ana to raw egg, white and yolk.

He gets a rough tummy is the white is cooked in something.

ukey Fri 26-Jul-13 13:41:55

I don't think I would risk it...

though how is your son effected by egg?

Don't really know but the most likely allergen in eggs is the proteins in the white of the egg.

I'd imagine (I have no scientific knowledge but I have a son with egg allergy and wouldn't chance a duck egg on him) that all egg whites have the same proteins.

Fortunately recently he's been able to tolerate egg yolks and can now eat an egg yolk omelette smile.

Have you tried just using the egg yolks? That's where all the nutrients are anyway.

Just that really.

Ive never seen it mentioned before so presumably its not a regular occurrence, being allergic to hen eggs not ok with duck eggs.

Still, I thought Id ask..... grin
