How do horses get tapeworms?

Horses commonly get tapeworms from ingesting contaminated food or water. Tapeworm eggs or larvae can be found in pastures or other areas where horses graze, and horses may ingest these eggs or larvae while eating grass or hay. These eggs then hatch into tapeworm larvae, which attach to the horse's intestinal wall and mature into adult tapeworms. Additionally, horses can also get tapeworms from ingesting intermediate hosts, such as fleas, lice, or mites, that carry the tapeworm larvae. It is important to regularly deworm horses to prevent tapeworm infections and keep them healthy.
