Also, containers that haven't been properly washed and food that hasn't been properly rotated are havens for bacteria. Employees who don't wash their hands before returning to their shift can unknowingly spread bacteria and other diseases. That is why it is of the utmost importance that employees wash their hands and also why every fast food restaurant should have at least one sink designated for hand washing with properly posted instructions, the necessary soap, paper towels, and so forth. Even pests can present a challenge to cleanliness in fast food working environments, so it is important that restaurants are regularly treated for pests. No one wants an unwelcome visitor in their food, but it has and does happen more than we'd like to think.
Hair nets are a good idea for keeping stray hairs out of food.
Hats are more often the rule, but less effective in preventing hairs from getting into the food. Wearing long hair back in a ponytail or braid is a must. Neat grooming can also minimize the likelihood of stray hairs getting into food. Fast food is convenient but not always clean. Every establishment should go above and beyond the norm to ensure that food is properly handled although sadly many fall short.
