EG, a 13-year-old teenager from Redondo Beach, California and his parents were vacationing in the French Alps atop the famous Col de la Madeleine. Wanting to do his part so his parents could have a relaxing vacation, EG decided to make them breakfast. Using his familiar techniques from home he made them each two slices of toast with butter, two eggs he put in boiling water and let steep for four minutes, a half-cup of cottage cheese topped with three pear slices. Later that evening, after dinner, his parents had a fever, headache, nausea, vomiting, and abdominal cramps.

The next morning they were also experiencing bloody diarrhea and were ill enough to visit the local emergency room. What was EG's parents' diagnosis?
