Which of the following does not belong to the Big 5 foodborne illnesses?

The Big 5 foodborne illnesses are a specific group of illnesses recognized by the Centers for Disease Control and Prevention (CDC) that are known to cause severe illness and outbreaks, particularly in food service settings. The illnesses in this group include Salmonella, Norovirus, Hepatitis A, and E. coli, while Listeria is commonly associated with foodborne illness but is not classified as part of this particular group.

Listeria monocytogenes is known for causing listeriosis, which can be severe, particularly for vulnerable populations. However, it is not included in the Big 5 mainly because the primary focus of the Big 5 is on pathogens that are more frequently linked to outbreaks in foodservice contexts and are of immediate concern for health and safety protocols.

Understanding this classification helps food handlers maintain high safety standards by keeping track of the pathogens that pose the greatest risks in food preparation and handling practices.
