Which of the following is a vehicle for Salmonella transmission?

• A. Eggs
• B. Meat
• C. Bread
• D. Water

Answer: (B)

The key idea is that Salmonella is commonly transmitted through animal-derived foods that can harbor the bacteria and be mishandled in cooking or through cross-contamination. Meat is a frequent vehicle because animals can carry Salmonella in their intestines, and during slaughter, processing, or cutting, the bacteria can contaminate surfaces and products. Ground meat in particular can spread bacteria throughout the product, increasing the chance of illness if not cooked thoroughly. Eggs are also a known vehicle, but in this set, meat represents the broadest and most consistently implicated source across common outbreaks, while bread is unlikely to harbor Salmonella unless contaminated after baking, and water transmission generally relates to specific contamination events rather than a routine driving vehicle in typical food settings. Proper cooking and preventing cross-contamination are essential to prevent transmission from meat.
