Abstract
BackgroundIn recent years, investigations of Toxoplasma gondii infection in poultry (chickens, ducks, and geese) have been reported worldwide, including China. However, little is known about the prevalence of T. gondii infection in poultry in northeastern China. Therefore, the present study was performed to determine the prevalence of T. gondii infection in slaughtered chickens, ducks, and geese in Shenyang, northeastern China.MethodsIn the present study, the seroprevalence of T. gondii in 502 adult chickens, 268 adult ducks, and 128 adult geese was surveyed using the modified agglutination test (MAT).ResultsThe seroprevalences of T. gondii were 5.8%, 7.8%, and 4.7% in chickens, ducks, and geese, respectively. Prevalence was higher in free-range groups (11.2%, 12.3%, and 8.9%) than caged groups (4.7%, 7.5%, and 6.0%), and there was a statistically significant difference only between free-range chickens and caged chickens, but no significant difference was found between free-range ducks, geese and caged ducks, geese.ConclusionsThe present study shows the prescence of T. gondii infection in slaughtered chickens, ducks, and geese in Shenyang, northeastern China, which suggests that consumption of poultry meat in Shenyang may pose a potential threat to human health and should be given attention.

Summary
Investigations of Toxoplasma gondii infection in poultry (chickens, ducks, and geese) have been reported worldwide, including China. Little is known about the prevalence of T. gondii infection in poultry in northeastern China. The present study was performed to determine the prevalence of T. gondii infection in slaughtered chickens, ducks, and geese in Shenyang, northeastern China. Meat from T. gondii-infected poultry (including chickens, ducks, geese, and pigeons) is consumed widely in many countries, including China, and is known to be the primary source of infection for humans [1,6]. There have several reports of T. gondii infection in chickens, ducks, and geese in China [8,9,10,11]. There is no information regarding T. gondii infection in ducks and geese, and only limited information on seroprevalence of T. gondii in chickens in Liaoning, China, an investigation of the seroprevalence of T. gondii infections in chickens, ducks, and geese was undertaken
