Not sure if this is helpful or one of those "I didn't need to know that" situations, but I recently saw a video where a guy said he developed an allergy to cockroaches after working with them for a while. He said that he simultaneously developed an allergy to pre-ground coffee and discovered that it was because there's a "maximum allowable animal protein" in those products; he's since switched to whole bean coffee and can drink it without breaking into hives.
Ignore me if this isn't applicable. I thought I'd share, just in case.
Interesting!
I did use whole beans and ground them myself. I got rashes, went to the doctor, they found nothing. A cream worked, made it for away for a little while, and I only had to use the cream a couple of times a month.
Two years after my rashes appeared, on a Sunday morning, I had a cup of coffee. I then had to throw up. Felt perfectly give afterwards, but the coffee smelled and tasted like shit. Googled, and it turns out it was sudden coffee aversion.
About a month later, all my rashes were gone. Have not drunk coffee in 3 years, and no rash problem! My hypothesis is that I got it from drinking too much coffee, as I drank nearly 2 litres a day... The only thing I miss is coffee and Baileys/Sheridans.
