Fruit carts... They're everywhere, and what can go wrong? Food poisoning from fruit? People are scared of the "roach coaches," but you can't be scared of these.
If you are, I'd say you're more afraid of the dude behind the cart, and even though they may not speak much English some of the time, they're so far cool. This dude had gold teeth and gave me a big ass smile for the "cinco" I bought.
