A normal clean toilet is no danger, same as everywhere else in the world, but if you're going to the loo in one of those ramshackle open-to-the-elements rustic outhouses, you might want to check the seat.
Real, but usually only if you have an 'outside toilet'; I had one of these in a WWII-era home located in a country area of Australia, and there would often be red-back spiders + eggs under the seat. Still, easily checked for and destroyed.
Considering that I live in rural Minnesota and if my shoes are left outside in summer, I check them for wasps or snakes before putting them on, I'd go for them being real.
