Giải thích
Norovirus is extremely contagious and spread by the fecal-oral route, so excluding sick employees and strict handwashing plus no bare-hand contact with ready-to-eat food are the key controls. Freezing does not kill Norovirus, sanitizer alone is not effective against it, and 135°F is a holding temperature, not a kill step.
