Final answer:
A food handler diagnosed with an illness caused by norovirus, shigella sp., nontyphoidal salmonella, Hepatitis A, or salmonella typhi should report the illness to their supervisor to prevent contamination and spread of the disease.
Step-by-step explanation:
If a food handler is vomiting or has diarrhea and is diagnosed with an illness caused by norovirus, shigella sp., nontyphoidal salmonella, Hepatitis A, or salmonella typhi, the correct action they should take is to report it to their supervisor. These illnesses are highly contagious and can easily contaminate food, leading to a foodborne disease outbreak. Good hygiene and food safety practices, including reporting illnesses, are critical in preventing the spread of these pathogens.
It is important for food handlers to understand that pathogens like norovirus can be spread when infected individuals handle food without proper handwashing, especially after using the bathroom. Similarly, bacteria like salmonella typhi and hepatitis A virus can cause serious diseases, with symptoms that include gastrointestinal distress and even more severe health complications. Reporting symptoms to a supervisor ensures that appropriate measures are taken to prevent other people from getting sick, maintaining safety within the dining establishment.
