You are very naughty handling stock feed without a mask when it's so dusty, Copago! Tsk ! Tsk! Use gloves too!

Even the lucerne will have me lighting up - or stud mix if handled too much.
I keep a mask and gloves in the feed shed, but I do use them but not all the time and then pay for it!
I've learned to minimise contact - although seeding rye grass is also very nasty - and I've resorted to keeping 25mg prednisolone in the cupboard for backup.
I'm not anaphylactic so can still breath safely - but I end up with a badly swollen face and can't see - which happens overnight.
I use regular dosed of vitamin C and zinc to boost my immune system and that seems to help minimise my reaction.
Discovered years ago when I was having allergy tests that I'm allergic to 'caine' mixtures, lognocaine etc and local anaethestic bases that dentists commonly used, which explained the all body rash I acquired after a chronic mosquito attack when I came up in welts after using an otc cream for he itch! :P
I have two friends who carry epi-pens. One is severely allergic to any kind of shellfish - which fortunately can be indentified from a distance - so needs back up for any sauce or dressing based on shell fish that might be unidentified when eating out.
The other to insect bites - interesting when we're out walking or bike riding a lot.
In both cases - yes off to hospital, but they were both told that the epi-pen will also calm the reaction and to rely on that 'mentally' as severe stress (like thinking about how bad it might be) will exacerbate the reaction.
Both my MIL and SIL have major breathing problems with sunflower or anything in that family - and tomato seeds - so I don't have anything related in any food preparation.
