Snapshot A 25-year-old medical student goes to an urgent care clinic for vomiting and nonbloody diarrhea. He is on a tight budget and has recently been relying on buying bulk amounts of rice and making fried rice. He makes a batch every Monday, and reheats it throughout the week. He finished off his last batch for lunch around 3 hours ago and admits that he had accidentally left that portion out overnight. He reports feeling nauseous. On physical exam, he is afebrile, has hyperactive bowel sounds, and abdominal tenderness. His physician reassures him that this disease is likely self-limited and suggests that he vary his diet.
