More than 200 students from Kituro High School in Baringo County have been sent home over suspected food poisoning.
The students, who complained of stomach pains and headache, were treated at a Kituro health centre before being sent home.
The Principal Salina Rotich on Wednesday confirmed that the students were sent home on Monday and that some of them had returned after recovering.
Mr Machocho said they suspect a supplier brought stale bread to the school canteen. The supplier has since been suspended.
According to a medical officer at Kituro health centre, who sought for anonymity, more than 50 students tested positive to food poisoning.
A spot check by the Nation at the health facility Wednesday found more than 12 students who were complaining of stomach pains waiting to be attended to.
Baringo Central Public Health Officer Agnes Chesire said they took samples from students from the school for testing and no cholera was detected.
