What are the "Big Six" pathogens that cause most foodborne illnesses?

The "Big Six" pathogens are critical to understand in food safety as they are responsible for the majority of foodborne illnesses. The correct answer identifies these six pathogenic microorganisms, which include Norovirus, Salmonella Typhi, non-Typhoidal Salmonella, Shigella, E. coli O157:H7, and Hepatitis A.

Norovirus is known for its rapid spread and is a leading cause of gastroenteritis worldwide, often linked to contaminated food and water. Salmonella Typhi is specifically associated with typhoid fever, whereas non-Typhoidal Salmonella can lead to gastrointestinal infections. Shigella is another significant pathogen that causes diarrhea and is spread through contaminated food and water. E. coli O157:H7 is notorious for causing severe food poisoning and can be found in undercooked beef and contaminated vegetables. Lastly, Hepatitis A is a virus that can result in liver infection and is often transmitted through contaminated food.

Understanding these pathogens is essential for food safety training as they highlight the importance of proper food handling practices to prevent foodborne illnesses. This knowledge empowers food managers to implement effective control measures in food preparation and service.
