Which of the following is NOT among the five common pathogens in raw milk?

• A. Norovirus
• B. Campylobacter
• C. Salmonella
• D. E coli O157:H7

Answer: (A)

Raw milk safety discussions focus on the pathogens most commonly associated with unpasteurized milk. The standard five commonly cited are Campylobacter, Salmonella, and Escherichia coli O157:H7, along with Listeria monocytogenes and Staphylococcus aureus. Norovirus, while a frequent cause of gastroenteritis from contaminated foods, is a virus and is not part of that typical raw-milk pathogen list. So Norovirus is not among the five commonly identified raw-milk pathogens. The other options are on that standard list, which is why they’re considered the usual suspects in raw milk-related illness.
