Question

Which one of the following microorganisms is NOT a causative agent for food borne diseases?

• A. Campylobacter jejuni
• B. Clostridium perfringens
• C. Norovirus
• D. Borrelia burgdorferi

Hint:

Borrelia burgdorferi causes Lyme disease, which is transmitted by ticks, not foodborne routes.

Answer 1

The Correct Option is D

Let's go through each of the microorganisms and their association with foodborne diseases: - Campylobacter jejuni (Option A): Campylobacter is a well-known cause of bacterial gastroenteritis, often transmitted through contaminated food, especially undercooked poultry. It is a major cause of foodborne illness. - Clostridium perfringens (Option B): Clostridium perfringens is another common bacterium that causes food poisoning, usually through the consumption of improperly cooked or stored meat. It produces toxins that cause gastrointestinal illness. - Norovirus (Option C): Norovirus is a highly contagious virus and one of the leading causes of foodborne illness worldwide. It spreads through contaminated food, water, or surfaces. - Borrelia burgdorferi (Option D): Borrelia burgdorferi is the bacterium responsible for Lyme disease, transmitted primarily by ticks, not by food consumption. It does not cause foodborne illness. Thus, the microorganism that is not a causative agent for foodborne diseases is Borrelia burgdorferi. Final Answer: \[ \boxed{\text{(D) Borrelia burgdorferi}}. \]
