Toxoplasmosis: The Heart of the Diagnosis

Abstract

Toxoplasma gondii is a common parasite that infects warmblooded animals, including humans, and is a foodborne pathogen. We report a case of acute toxoplasmosis in a 76-year-old man after ingestion of the undercooked heart of a white-tailed deer (Odocoileus virginianus) in Tennessee. The patient's adult grandson, who also consumed part of the heart, became ill with nearly identical symptoms, though he did not seek medical care. This case highlights important public health concerns about deer-to-human transmission of Toxoplasma.
