A total of 68 students from St.

Thomas Aquinas Igumori Secondary School in Mbeere South, Embu County, were treated for stomach aches and diarrhea after consuming suspected contaminated beef.

According to the school principal Paul Mwaniki, a bull was slaughtered on Wednesday for a feast, and a veterinarian inspected and certified the meat as safe for consumption.

Most of the beef was eaten on the same day without incident.  However, a section of teachers and students, including form four candidates, consumed the bull's head on Thursday.
