At first I thought the question was meant to be tongue in cheek, but looks like I was wrong.
I wash everything before using it. Maybe more than needed but nobody get's diarrhea when they eat at our house.
When we eat out there is a 1 in 3 chance at least one of us will get sick.
My thinking is that if a place is not sanitary there is no way I am going to eat anything there.
Someone mentioned workers eating fruit/veggies in the field.
I don't even want to think about the parasites they have living inside of them.
This is a short blurp I copied from the CDC about sources of parasites in humans.
Raw vegetables that have been contaminated by human or animal feces;
Some foods are contamined by food service workers who practice poor hygiene or who work in unsanitary facilities.
Symptoms of foodborne parasitic infections vary greatly depending on the type of parasite. Protozoa such as Cryptosporidium spp., Giardia intestinalis, and Cyclospora cayetanensis most commonly cause diarrhea and other gastrointestinal symptoms. Helminthic infections can cause abdominal pain, diarrhea, muscle pain, cough, skin lesions, malnutrition, weight loss, neurological and many other symptoms depending on the particular organism and burden of infection. Treatment is available for most of the foodborne parasitic organisms.
Here is a photo of what you ate when you didn't wash your veggies.
