E. coli outbreak at MSU: Six Michigan State University students were struck ill by E. coli poisoning and another 13 students are considered possible victims, raising the number of students associated with the outbreak to 19, up from about ten last week. The students all had cases of bloody diarrhea, the most common symptom of E. coli contamination. Health officials hope to nail down the possible sources once testing confirms which cases stem from the same outbreak.
