Again, you're being short sighted. A contagion or a contaminant does not
have to originate from a fish to affect a fish. As I said before there
are
plenty of parasites (e.g. any number of digenetic trematodes) and viral
diseases that use secondary hosts in order to infect tertiary hosts--a
secondary host could be something like a bird or a rodent.

I guess I'll worry about it if and when it happens. Since it hasn't
happened in all these many years I wont worry about it. I'm more concerned
with my own food being contaminated than finding contaminated larvae in old
pots and tubs behind the house.
