Which of the following would NOT be a means of reducing the risk of zoonotic disease transmission?

  1. Vaccination of animals

  2. Wearing gloves when handling animals

  3. Regular handwashing after animal contact

  4. Feeding animals raw food

The correct answer is: Feeding animals raw food

The choice of feeding animals raw food is correct as it does not help reduce the risk of zoonotic disease transmission; in fact, it can increase it. Raw animal products may contain harmful pathogens that can be transmitted to humans, such as Salmonella, Campylobacter, or E. coli. Feeding animals a diet that includes raw food can expose both the animals and their handlers to these pathogens. In contrast, vaccination of animals significantly reduces the incidence of certain zoonotic diseases by enhancing the animals' immune response and providing them with protection against specific pathogens. Wearing gloves when handling animals is an effective barrier method to prevent direct contact with pathogens that might be present on their skin or in their bodily fluids. Additionally, regular handwashing after contact with animals is a fundamental practice that eliminates pathogens from hands, further decreasing the risk of disease transmission. Together, these measures are vital for maintaining health and preventing zoonotic infections.
