As such, the 11 schools they cater for have been temporarily re-assigned to other caterers to ensure meal service continues uninterrupted. The ministry said at Warrenville the zonal manager and resident quality assurance officer visited the school and met with the principal and staff. Their initial investigations suggest that National School Dietary Services Limited's meals were not the source of illness. The ministry advised that any students of Warrenville TIA experiencing vomiting and diahorrea report immediately to the Chaguanas Accident and Emergency Department or visit their doctor. The school will be sanitised over the weekend. The Ministry of Health has instructed that samples be taken from affected students and sent to the Eric Williams Medical Sciences Complex for testing.
