There are several different types of intestinal worms that may affect your dog and cat, some of which may be hazardous to human health as well. Find out more about these parasites below:
Toxocara canis and Toxascaris leonina are the primary roundworms of concern in dogs; Toxocara cati is the primary roundworm of concern in cats. Puppies and kittens acquire infections by these worms through the placenta and/or their mother's milk. Adult animals may pick up the infection by coming in contact with the worm eggs in infected soil, dust and faeces.
T.canis and T.cati are both zoonotic, meaning that they can cause disease in humans, if accidentally ingested. A condition known as visceral larval migrans or less frequently, occular larval migrans, may be observed in humans following an infection with either T.canis or T.cati.

Tapeworms in dogs and cats may be acquired by the accidental ingestion of infected fleas. Cats may also acquire tapeworms when they ingest infected rodents. Dipylidium caninum and Taenia ovis is the dog tapeworm and Taenia taeniaeformis is the cat tapeworm.
For lifestyle block and farming communities - when accidentally ingested, the eggs of the dog tapeworm Taenia ovis may cause sheep measles in sheep. Read more about how it happens here. Therefore, it is important that rural and farm dogs are wormed regularly with a product that confers protection against Taenia ovis.
Infections with Echinococcus spp. tapeworms in dogs and cats are rare; and it may cause disease in humans. However, New Zealand has been declared free of Echinococcus spp. of tapeworms since 2000.
Ancylostoma caninum and Uncinaria stenocephala are the primary hookworms of concern in dogs. Hookworms are transmitted from the dam to the puppies via the milk or through the skin; adult dogs may pick up the infection from being in contact with infected faeces, soil or moist environment.
Hookworm infections in cats are possible but seen less commonly. The Ancylostoma tubaeforme species of hookworms are responsible for infections in felines. Infection routes in felines are thought to be similar to those in dogs.
Hookworm infections, especially with the Ancylostoma spp. are zoonotic to human health, because the larvae of these hookworms can migrate under the skin to cause a condition called cutaneous larval migrans. Read more about hookworm infections here.
Trichuris vulpis is a type of whipworm that affects dogs; Trichuris infections are rarely seen in cats. Trichuris eggs can remain in the environment for up to 5 years, and dogs can easily become infected by coming into contact with these eggs. Read more here.
