What is a preventive measure against roundworm transmission to humans?

Deworming pets regularly and maintaining good hygiene practices are effective preventive measures against roundworm transmission to humans. Roundworms, particularly Toxocara canis and Toxocara cati, can be transmitted through contaminated feces. When pets are dewormed consistently, it reduces the worm burden in their system, thereby decreasing the likelihood of shedding eggs in their feces, which can then contaminate the environment and potentially infect humans.

Good hygiene practices complement deworming by ensuring that pet owners wash their hands thoroughly after handling pets or cleaning up after them, and by keeping living areas, such as yards and litter boxes, clean and free of fecal matter. This combined approach is essential in minimizing the risk of zoonotic transmission of roundworms.

In contrast, while regularly washing pet bedding and feeding pets packaged food are good practices, they don’t directly address the transmission route of roundworms. Avoiding outdoor activities is impractical and does not contribute significantly to the prevention of roundworm transmission. Pets and humans need regular outdoor exercise, which should be safely managed through hygiene practices and appropriate veterinary care.
