All of the following statements are true EXCEPT?

The statement regarding the return to work after 24 hours of no symptoms of Hepatitis A is not accurate. Food handlers who have been infected with Hepatitis A must follow specific guidelines set by health authorities, which generally require a longer absence from work, particularly due to the virus's potential to spread through food handling. These guidelines typically specify that a food handler should be excluded from food service work for at least seven days after the onset of symptoms or until they have been cleared by a healthcare professional, depending on local regulations.

The other statements are true and reflect important aspects of food safety. Scombroid poisoning is indeed linked to eating certain fish, particularly those that are poorly handled or stored, leading to the development of toxins. The requirement of a doctor's approval for a food handler to return after recovering from Norovirus emphasizes the need for ensuring food safety to prevent further outbreaks. Coving is a design feature in food preparation areas that helps in easier cleaning and reduces the risk of food contamination, as it minimizes the number of places where dirt and bacteria can accumulate.
