Several kindergarten children in Michigan were hospitalized after ingesting a “foreign substance”

• Several kindergarten children in Michigan were hospitalized after ingesting a “foreign substance.”

• At first, school officials believed these were signs of carbon monoxide poisoning.

• However, the fire department has ruled this out and the investigation is ongoing.

Several kindergarten students at a Michigan elementary school were hospitalized Friday after ingesting a “foreign substance,” officials said.

Five students at Edgerton Elementary School, part of the Clio Area Schools district, were taken to a hospital in Flint, Michigan, Superintendent Fletcher Spears III said in a statement posted on Facebook.

As of Friday evening, four students remain in hospital and are in stable condition, officials said.

Initially, the statement said, school officials believed the students had inhaled carbon monoxide. But “the fire department and later Consumers Energy have ruled out carbon monoxide or other gases as the cause,” Spears said.

The classroom was evacuated Friday afternoon after dozens of students showed symptoms of carbon monoxide poisoning, MLive reported.

An investigation has been launched and is ongoing.

“We believe the students may have ingested a foreign substance,” Spears said.

“We will keep you updated on the status of the investigation,” Spears told parents and school officials. “Our custodial staff is thoroughly cleaning the room this weekend and we plan to resume classes on Monday.”

“Please keep all of Edgerton’s students and staff in your thoughts and prayers, especially our little ones in the hospital,” he said. “We wish them a full and speedy recovery.”
