One of the common sights one sees when walking the streets of Cuenca, is the fruit vendors selling their wonderful items from a wheelbarrow. I think the wheelbarrow business would be a good business, as the vendors are set up almost every two or three blocks. Mostly locals purchase these items, but occasionally I see tourists buying the fruit. It is so cheap and so good looking that one has to avoid temptation, unless they have the materials needed to cleanse the fruit appropriately.
I have learned over time that fruits and vegetables grown by root source (like potatoes, onions, garlic, carrots, etc) must be soaked thoroughly in the cleansing treatment or one will have a visit from the Grand Amoeba and trust me that’s not fun. The tree fruits and vegetables are safer, but still require a good cleansing. Ecuador has a bountiful supply of fruits and veggies, but I would urge you to make sure you treat them prior to consuming! Saludos!
