Which pathogens are most commonly associated with foodborne illness?

• A. Hepatitis A and Norovirus
• B. Salmonella and Campylobacter
• C. Listeria and Shigella
• D. Staphylococcus aureus and Clostridium perfringens

Answer: (A)

Foodborne illness is most often linked to viruses, with Norovirus being the leading cause of gastroenteritis outbreaks tied to contaminated food. Norovirus spreads easily through food handled by infected people, shellfish, and other prepared foods, and it needs only a small amount to cause illness, which is why it shows up so frequently in outbreak data. Hepatitis A is another virus that can be transmitted via contaminated food and water, contributing to foodborne outbreaks, though it occurs less often than Norovirus. Together, these two viruses represent the most common viral culprits associated with foodborne illness. While bacteria such as Salmonella, Campylobacter, Listeria, Shigella, Staphylococcus aureus, and Clostridium perfringens cause many cases, they do not account for outbreaks as frequently as Norovirus does, which is why the combination of Norovirus and Hepatitis A is identified as the most commonly associated group.
