Seroprevalence of Toxoplasma gondii infection in slaughtered pigs and cattle in Liaoning Province, northeastern China.
Toxoplasmosis is an important food-borne parasitic disease. In the present study, the seroprevalence of Toxoplasma gondii infection in slaughtered pigs and cattle was surveyed in Liaoning Province, northeastern China in May and June 2011. In total, 1,164 porcine serum samples and 646 bovine serum samples were collected from 5 counties and examined for T. gondii antibodies by an indirect hemagglutination test. Antibodies to T. gondii were found in 12.0% (140/1,164) of pigs, with some regional differences. The highest prevalence of 14.4% (47/326) was found in Fuxin followed by 12.5% (62/497) in Jinzhou; overall, 6.0% (39/646) was observed in cattle but with no regional difference (P > 0.05). Prevalence of T. gondii infection in pigs was also significantly higher compared to cattle (P < 0.05). The results of the present study indicate that infection with T. gondii in pigs and cattle is widely spread in China including Liaoning Province, northeastern China, and is, therefore, of public health concern.
