Infection with Toxoplasma gondii is one of the most common parasitic infections of human being and other warm-blooded animals. It has been found worldwide from Alaska to Australia. Public health organizations repeatedly encourage the collection of accurate data about T. gondii in animals and humans due to its medical importance as a major source of parasitic zoonosis. For these reasons, epidemiological updates on toxoplasmosis in livestock are strongly advised also to plan control strategies. In the present paper, seroprevalence data on T. gondii that have been recorded in livestock from different Italian regions over the last 3 decades are reviewed, showing the high level of exposure of livestock to this parasite.
