Which foodborne pathogen is most associated with infected workers who fail to wash their hands after using the restroom, and spreads easily through ready-to-eat food?

解析

Norovirus is highly contagious and spreads through the fecal-oral route when infected workers touch ready-to-eat food with contaminated hands. Thorough handwashing, no bare-hand contact with ready-to-eat food, and excluding sick workers are the main controls. This is why workers with vomiting or diarrhea must not handle food.
