Before self diagnosising, I suggest you go to an allergist. That's what I am doing because I have had some violent reations during a brew day. I own a small commercial brewery, which I have been running for the last 4 years. It wasn't until October 2013 that I started noticing hives. I wasn't sure what it was and it went away after taking some allergy meds. April of this year, I nearly dropped dead at the door of the brewery, thanks to an epipen and the quick action of the fire department, I lived to brew another day. I had minor reactions on and off, then, last month, I went anaphylaxic again. I am on a virtual medicine cabinet of meds now, it helps, but under doctor's orders, I am not going in. We had a team meeting earlier this week at a brew pub, it happened to be a brew day, and even though the brewing area was enclosed, I had a minor reaction. The only thing I am allergic to that could cause a reaction are dust mites, hard to avoid those. From what I hear, there are a lot of dust mites in malt and they surface during milling not to mention spores. I am not being asked to bring in a sample of malt and some wort. I can drink beer no problem and it isn't hops, I have been growing them for the last year and just harvested them. I am being told now that I may have to go in with an environmental or hazmat suit, because I seem to have contact allergies as well. It is especially worrisome seeing as brewing is my chosen career. It might also be stress seeing as I was clocking in excess of 100 hours a week. I am not going to get worked up about it until I get tested for malt and perhaps wort. Anyone else have this issue?
