Toxoplasma gondii Prevalence in Farm Animals in the United States
Toxoplasmosis is a significant public health problem in the US with more than one million people newly infected each year, according to new research from the USDA. Seroprevalence in pigs and chickens from non-biosecure management systems is high. Clinical disease and high seroprevalence occur in sheep and goats, while beef cattle do not appear to be important in the epidemiology of Toxoplasma or in transmission to humans.
