Two AISD schools, Allison and Kocurec Elementary Schools, found glass in their food.
After the glass was found in food 18 Austin schools removed glass panels from cafeteria serving lines.
On Thursday a cafeteria worker at Allison Elementary School found pieces of glass in pinto beans. She removed the tray and called the supervisor of Health Services to investigate.
They discovered the glass over the food in the serving line was breaking off. A similar incident took place at Kocurek Elementary School.
A spokesperson for AISD said no children were injured in either incident.
New glass will take between two and three weeks to be installed. In the meantime, heavy duty plastic has been used to maintain food safety.
