An investigation is underway at an Alaskan elementary school after a dozen students drank floor sealant they thought was milk, school officials announced Wednesday.

On Tuesday, students enrolled in a summer program at the Sitʼ Eeti Shaanáx̱ Glacier Valley Elementary School were served breakfast beginning at 8:45 a.m., according to a statement on the Juneau School District website.

A short time after, students began to complain about the milk tasting bad and burning their mouths and throat.

“It was found that the ‘milk’ served was actually a floor sealant resembling liquid milk,” the statement said.

Staff immediately advised students to stop consuming the chemical and it was removed. The parents and guardians of the students who drank the floor sealant were informed of the incident.

One student did receive medical treatment and two others who were picked up may have also sought treatment, the statement said. 

Staff removed the remaining product and placed it in the chemical/hazardous storage. The Juneau Police Department, Juneau School District, NMS and City and Borough of Juneau are assisting in the investigation.
