The aim of the present study was to investigate the prevalence of antibodies against Toxoplasma gondii in turkeys and chickens on family farms in the semi-arid region of the state of Pernambuco, Brazil. In order to do so, 204 sera samples from turkeys were analyzed using the Modified Agglutination Test (MAT) and 322 sera samples from chickens were assessed using the Immunofluorescence Assay (IFA). Twenty-eight properties contained turkeys and 23 of these properties also contained chickens. The relative frequency of positive turkeys was 11% (21/204), with 46.6% (13/28) of the properties containing at least one positive turkey. The frequency of positive chickens was 25.8% (83/322), with 95.6% (22/23) of the properties containing at least one positive chicken. Based on the results of the present study, it was possible to conclude that turkeys can serve as an indicator of environmental contamination by oocysts of T. gondii. However, they are less effective than chickens bred in the same conditions. The increasing demand from consumers for naturally produced products should worry local sanitary authorities due to the high prevalence of antibodies against T. gondii found in this type of rearing system, particularly among chickens.
