Renota, a 51-year-old Slavic woman, lived in Romania with her family on a pig farm. She routinely slaughtered pigs and cooked pork for family meals. She had a wide variety of recipes that called for pork. A few days after preparing one of her famous pork dishes, Renota experi- enced diarrhea, abdominal pain, and chronic indigestion. She went to her family physician and explained her symp- toms to him. The physician, who knew the family well and was familiar with the family business, immediately sus- pected a bacterial or parasitic infection. A stool sample for routine bacterial culture and 0&P study was collected from Renota and submitted to the local diagnostic laboratory.
