Food Worker Handwashing and Restaurant Factors - EHS-Net Study Findings and Recommendations (cdc.gov)
Specifically: Handwashing may not always be enough to stop the spread of germs from hands to food. So the FDA recommends use of barriers such as gloves to stop the spread of germs. But research on handwashing and glove use in restaurants shows that these practices do not occur as often as they should. To improve these practices, we must understand factors linked with these practices. We interviewed and watched food workers to collect data on these practices.
Once again, please don't go in "quizzing" the people that are wearing gloves. These people are just following the rules. They should be regularly cleaning their can openers, changing the sanitizer, and changing gloves and washing hands between different foods. The front-line workers are following the rules to the best of their ability, and to the direction of their management staff. instead of quizzing them on the reasoning behind why they do things (the answer is always because they are paid to), you should ask about their day, if they got to get off the ship, when they get to go home. These people are my people, I respect them and appreciate them. I currently and have always worked in food service, it's a hard enough job without know it all's trying to show how much smarter they are then the rest of us.
