We spent a few months in China, and you can't believe the unsanitary conditions in the marketplaces (where most Chinese go to get their food.)
Chickens, dogs, cats, rats, snakes, (you name it, they eat it)...all being held in cages, waiting to be slaughtered and then their "guts" just get washed into the street and down into the sewage system.
Smelly and messy...I was paranoid about us cleaning our hands after we touched put on or took off our shoes, LOL.
One of my daughter's co-workers just got back from China and couldn't believe they didn't have flush toilets -- just holes in the ground! Makes me wonder if they are going to have modern "facilities" built in time for the Olympics for all of the athletes to use!
My gosh,what did you eat?
