Primary Investigator:

This study demonstrates the continued reduction in Toxoplasma antibodies in the Midwestern commercial market swine herd from earlier surveys. The prevalence of 0.75% is consistent with the National Animal Health Monitoring System (NAHMS) 2000 survey of finishing swine. Further it provides an indication that the risk factors associated with antibody presence may be related to on-farm management practices. These findings are consistent with the known concerns about contact with cats and cat feces as a major exposure risk factor. Efforts to limit access of swine to infective material will continue to reduce prevalence of Toxoplasma antibodies in market swine.
