“The school children experienced conditions such as vomiting, stomach cramps, and headaches after consuming chocolates sold by a hawker,” spokesman Sizwe Kupelo said.
The pupils, from Pumla High School, were being treated at Nompumelelo Hospital.
Last week, 24 people fell ill after they ate meat from a dead cow in Dutywa, Kupelo said.
“Six boys were also treated in hospital after they drank sour milk they bought at a local spaza shop in Peddie. They have all been discharged from hospital.”
