@kotigre,
I envision a dog scarfing up 58 delicious dollars...
Anyway, to your question. I was a lab technologist for a bunch of years, and we went through classical medical laboratory training. In fact, I took over for the guy who ran the parasitology lab while he went on a well deserved vacation. What this means in practical terms, is that when I came to work in the morning, there was an elevator dummy full of cartons of patient excretory samples, which needed various lab reviews. So, eh, I see $58.00 in such a situation, I'd pick it out, preferably with something like a paper towel, or, given time to access them,with some nice latex gloves. What I'd do after that, wash it? I dunno. I understand the motivation of the pet removal waste worker.
