Final answer:
A foodhandler who is diagnosed with norovirus must be excluded from work and not handle food until they meet health regulations and are symptom-free to prevent the spread of the virus.
Step-by-step explanation:
A foodhandler who is diagnosed with norovirus must be excluded from work and not allowed to handle food until they show no symptoms and meet local health department regulations. This might mean waiting until they are symptom-free for 24 to 48 hours or longer, depending on local laws.
This is crucial as norovirus is highly contagious and can be easily transmitted through food that has been contaminated by an infected person. When a foodhandler is diagnosed with norovirus, it is imperative for them to practice proper hygiene and follow the health guidelines to prevent further spread of the virus.
The infectious dose for norovirus is very low, and the virus can cause widespread infections in confined spaces like restaurants. The safety of consumers is paramount, and infected foodhandlers can cause an outbreak by transferring the virus to food items, which is why their exclusion from food preparation activities during their illness is non-negotiable. After recovery, it's essential for the foodhandler to follow strict hygiene practices and monitor for any recurring symptoms before returning to work.
