Not a primary reservoir for Campylobacter Jejuni?

• A. Poultry
• B. Unpasteurized milk/cheese
• C. Contaminated water
• D. Canned vegetables

Answer: (D)

Campylobacter jejuni is commonly found in animals, especially poultry, and is transmitted to people mainly through undercooked poultry or via cross-contamination. Unpasteurized dairy products and contaminated water are also well-recognized sources because the bacteria can be shed in animal waste and survive in these environments. These represent the typical reservoirs that lead to human infection.

Canned vegetables, on the other hand, are not a primary reservoir. The canning process uses high heat that effectively kills Campylobacter, and the organism does not typically persist in properly processed canned foods. That's why canned vegetables are not considered a major source of Campylobacter infection.
