After a visit to Chicago over Christmas, a couple returns to St. Louis with nausea, diarrhea, and cramping in the lower right quadrant of their abdomens. They admitted to indulging in a family favorite of chitterlings over the holidays.
 
  The routine stool culture of both individuals provided the same results:

   HE: yellow colonies
   PEA: no suspicious colonies
   Campy blood agar: no growth
