Direct contact with animal reservoirs includes exposure to which animals?

• A. Dogs
• B. Livestock
• C. Reptiles
• D. Fish

Answer: (C)

Direct contact with animal reservoirs in this context highlights which animals are known to carry pathogens that can be transmitted to humans through touch. Reptiles are a classic reservoir for Salmonella; they harbor the bacteria in their intestines and shed it in their feces, so handling a reptile or its habitat can contaminate hands, surfaces, or food-contact areas and lead to infection. This makes exposure to reptiles a well-established risk factor for Salmonella transmission in food protection and public health settings. Dogs and livestock can also carry pathogens, but they are not as prominently associated with direct-contact Salmonella transmission in typical exam contexts, and fish are linked to different risks. The upshot is that reptiles represent a primary direct-contact source of Salmonella to humans.
