Clostridium botulinum is the microorganism that causes foodborne intoxication, not infection, through the toxins it produces in contaminated food. Whereas Norovirus, Salmonella, and Shigella cause illnesses by infecting the host.
Identifying Non-Infectious Microorganisms
The task is to identify which of the following is not an infectious microorganism that causes foodborne disease, but rather causes food-borne intoxication:
A. Clostridium botulinum (botulism)
B. Norovirus
C. Salmonella
D. Shigella
Among the listed options, Clostridium botulinum is the one that causes foodborne intoxication instead of an infection.
Clostridium botulinum is a bacterium that produces toxins when it grows in food.
These toxins, rather than the bacteria itself, cause illness when ingested, known as botulism.
In contrast, Norovirus, Salmonella, and Shigella are all infectious agents that cause illness by infecting the host.
Question:
All of the following are infectious microorganisms (as opposed to microorganisms causing food-borne intoxication)except for:
A. Colstridium botulinum (botulism)
B. Norovirus
C. Salmonella
D. Shigella
