The Chicago Tribune reports that authorities are focusing on fruit cups and applesauce as possible reason for dozens of pupils at a Park Forest junior high school getting food poisoning.
Pupils were taken to local hospitals after becoming ill with food poisoning.
The president of the food company said they have taken samples of the fruit cups and applesauce that were served at lunch that day and are conducting testing.
The health department is also investigating the incident.
This was the second case of food poisoning in the last two weeks at the school, where earlier this month 17 students fell ill due to contaminated juice boxes.
