Paragonimus kellicotti Flukes in Missouri, USA

You don’t have to be a contestant on Fear Factor to eat unusual things. An investigation of 9 new cases of lung fluke infection in Missouri found that in all cases, patients had eaten raw crayfish while on rafting or camping trips and most had been drinking alcohol. Although all patients recovered after treatment, a few whose diagnosis was delayed had unnecessary procedures and serious illness. Physicians should consider lung fluke infection in patients with nonspecific cough and fever, especially patients who have recently returned from a recreational river trip. Crayfish in Missouri rivers often carry lung flukes and should not be eaten raw.
