I never wear gloves. I just wash my hands before and after dealing with the food. I also do not wear them while cleaning. I think that is ridiculous. I would only wear them if I was allergic to something. Also at aquariums they are dealing with many different types of foods and vitamins/chemicals that they use. Besides, have you ever held a rat or hampster after eating something without washing your hands. That could explain gloves as well. I have also been to seaworld and aquariums where many of them have touch tanks and feeding tanks, they don't make you wear gloves let alone just wash your hands before touching their animals. If you think wearing gloves is going to save you hand washing, think again. They are lined with powders to get your hands in and out of them. You will want to wash ur hands after that. I also know alot of people that are allergic to the latex and nylon surgical gloves, but nothing else. I just thought also the powder in the gloves could possibly be toxic to fish if somehow gets on food and is ingested. All in all i'll stick with washing my hands, besides I never had much luck keeping water out of them anyway.
