Yes, I would buy these bananas as they have a thick skin on them, so there is no reason not to.
When I was in India after an engine blew up on take off, and we were stuck there for 3 days, i looked out of my hotel room and they were unloading fruit and vegetables from a truck and standing in it -all vegetables just on top of each other.
Two men trampling in amongst them throwing them -that is something I would not willingly eat however had no choice and didnt get sick either.
I would buy bananas, because bananas are safely enclosed in the skin nature has given them, protecting them from external pollutants. I would not buy apples or pears or other fruits that have edible skin because I would be too conscious of the dirt on the fruit.
I was actually told by a friend that when you are traveling, one of the safest snacks to have is a banana.
When I first came to Melbourne I was luckyenough to have the Vic Market as one of my first finds, during a lunch break excursion. Bought a few bits of frit for myself and returned to work and was saying how wonderful I thought Vic Market was and asked a work colleague if she frequented the place because she lived nearby in Carlton. "no" she replied and went on to explain that she didn't know where the produce came from. She only shopped at her local greengrocer because she could trust him.
People are idiots.
