What mistake did the cook make by wearing single-use gloves while switching from raw beef to slicing hamburger buns?

Wearing single-use gloves provides a layer of protection against cross-contamination, but it is essential to change gloves and wash hands between tasks, especially when switching from handling raw meat to preparing ready-to-eat foods like hamburger buns. In this case, the cook's mistake was failing to wash their hands and put on new gloves after handling raw beef. This step is crucial because bacteria from raw meat can easily transfer to other foods, leading to foodborne illnesses if not properly managed. By not changing gloves and washing hands, the cook increased the risk of contaminating the buns and any other food items that would come into contact with them, which is against safe food handling practices.
