Zoonosis was defined for the first time by Wirchrow to indicate diseases transmitted from animals to humans. Later, it was understood that diseases can be transmitted from animals to humans, as well as from humans to animals. Zoonotic parasites can be transmitted from animals to humans in many different ways. According to this, it can be orally with infected food and water, or it can introduce various forms of parasites carried by some arthropods, which serve as respiratory, skin, or intermediate hosts, into the host organism. When zoonotic parasites are mentioned; these are protozoans (Toxoplasma gondii, Leishmania spp, Babesia spp, Cryptosporidium spp, Giardia intestinalis, Entamoeba spp, Balantidium coli et al.), helminths (Fasciola hepatica, Opistorchis felineus, Heterophyes heterophyes, Paragonimus westarmani, Schistosoma spp, Echinococus granulosus, Echinococus multilocularis, Taenia spp, Diyhllobothrium latum, Hymenolepis spp, Ancylostoma caninum, Strongyloides stercoralis, Trichinella spp, Dirofilaria spp et al.), arthropods (fleas, ticks, mosquitoes, myiasis flies, Demodex spp, Cheyletiella spp, et al.). Zoonoses are important in two ways. The first is human and animal health, and the second is the food safety of humans and animals in the food chain. In this section, these issues are considered together.
