What is the most common route of Salmonella infection?

• A. Oral (the most common route)
• B. Transovarian (poultry)
• C. Vector
• D. Environment (stable)

Answer: (A)

Salmonella infections are most often acquired by ingesting contaminated food or water—an oral exposure to the organism. Foods such as poultry, eggs, dairy, meat, and produce can carry the bacteria if they’re tainted and not handled or cooked properly. The risk is reduced with thorough cooking, pasteurization, and good kitchen hygiene. While transovarian transmission can contaminate eggs from infected hens, and environmental or vector exposures can contribute in certain settings, these are not the typical pathways for the majority of human infections. Therefore, the oral route via contaminated food or water best explains the common pattern of Salmonella illness.
