I had a reaction exactly as described by Deb, about 30 years apart!
Mid-sternal pain, nausea, vomiting, chills, cramps and severe distress.
After the first experience I fastidiously avoided anything with even the suggestion of duck. My friend’s suggestion of her farmyard duck eggs didn’t even get a glance.
At a restaurant recently, I went to the trouble of asking, twice, what fat their potatoes were prepared in. They did not bother to verify.
It was a good thing I had been seated near the bathroom. I had the same unmistakeable reaction within minutes of ingesting the potatoes. I had eaten no meat that day.
I thought it could have been due to my Jewish heritage ( both Sephardic and Ashkenazi ), but I researched and found that Schmalz can be made from duck or chicken. Maybe none of my ancestors ever ate duck, because I have absolutely no tolerance for it.
