Which statement describes why caution is advised when handling certain pets to prevent cross-contamination?

• A. Cats
• B. Rabbits
• C. Lizards, snakes, frogs
• D. Fish

Answer: (C)

Handling certain pets requires extra caution because some animals can carry germs that spread to people or to surfaces you touch, causing cross-contamination. Reptiles and amphibians—like lizards, snakes, and frogs—are well known for shedding bacteria such as Salmonella into their environment, their droppings, and onto their skin. You can transfer those germs just by touching the animal or its enclosure, then touching your face, food, or kitchen surfaces. That’s why thorough hand washing after handling them, keeping their habitat away from food prep areas, and using separate cleaning tools and disinfectants are essential practices.

Other pets, like cats or fish, can carry microbes too, but the risk of spreading contamination through common handling and household surfaces is especially pronounced with reptiles and amphibians, which is why this option is the best choice.
