Which organism is NOT part of the Big Six Pathogens?

• A. Listeria monocytogenes
• B. Norovirus
• C. Hepatitis A
• D. Shigella spp.

Answer: (A)

The Big Six Pathogens are the group of organisms that safety training prioritizes for preventing foodborne illness. In this course’s material, Listeria monocytogenes is not included in that prioritized list, whereas the other organisms shown (Norovirus, Hepatitis A, Shigella spp.) are part of the Big Six. So, Listeria monocytogenes is the organism that does not belong to the Big Six in this context. This reflects how different training programs may define the Big Six slightly differently, but within this material, Listeria is treated as outside the set.
