La toxoplasmosis is a common infection in France. In animals, it affects both mammals and birds. In mammals, the prevalence varies according to the species: 30% for sheep, 23.5% for pork, 12.5% for cattle and 6.5% for equines1. In humans, toxoplasmosis, whose definitive host is the cat, remains common with varying degrees of prevalence depending on the region of the globe and sometimes even within a single country. In France, prevalence is on the decline but remains high. From 82% in 1960, it has been declining steadily for 40 years: 66% in 1982, 54% in 1995 and 44% in 2003.
Toxoplasmosis has a significant impact. Among farm animals, it is the leading cause of abortive diseases, particularly in ewes if the infection occurs during the first gestation. Each year, it is responsible for nearly 1 million abortions in Europe, which highlights the significant economic impact it has on breeders.
Toxoplasma gondii eis found in the meat of major livestock (sheep, cattle, pigs). The absorption of undercooked meat or sausage meat is the main vector of disease transmission from animals to humans.
