It is very common and disgusting. Think about it. Your in the middle of a 200 acre farm and nature calls....If there wasn’t a bathroom nearby what would you do?
Granted normal people like you and I, would probably find a more suitable area to do our business where we weren’t squatting over the veggies.
Just another reason to wash your fruits and veggies very very well.
When we receive food from countries that don’t regulate anything, this is what you get.
The best regulations are the self imposed ones. I know, we're busy people. We got mortgages to pay and car payments to make and beer to drink and sports to watch! Go Galt. You might not have as many material things if you do, but I'd bet we'd be much happier, and wouldn't be eating food that has been purposely crapped on.
