Case of the Week 676

This week ' s case is generously donated by Dr. Adrienne Showler. The following was passed in stool by an ' adventurous eater ' , who regularly enjoys raw fish dishes, and also has tried raw beef and pork dishes in the United States. He reports passing similar objects on 4 separate occasions, and the length of each was between 1 and 3 feet. Unfortunately he didn ' t collect the samples (!), so we only have these photographs:Likely identification?
