I Thought I lost it

I've been looking for a new job in a new town, quite the chore.  After what has seemed like very successful interviews, I don't get the job.  I'm now being told that I can't mention my latex allergy.  These people have all asked me why I've changed careers, because I wanted to make $7 an hour less than I was???  That's stupid, but it's what I've had to do for safety.  I'm at a loss, and going to try to revamp my job search, too bad some of those jobs I already interviewed for would have been a great fit.
