NEW HANOVER, Pa. (CBS) — Students at a Montgomery County grade school were served pet treats by a recess aide, school officials said.

The incident happened Thursday at the New Hanover Upper Frederick Elementary School in New Hanover Township.

According to a statement from Boyertown Area School District Superintendent Richard H. Faidley, a part-time recess aide at the school distributed pet treats to approximately 75 fourth grade students.

The statement says the treats may have been misrepresented as cookies or crackers. Faidley said the school was uncertain how many students actually ate the pet treats.

A portion of the statement read: “Our research on the product indicates that the treat ingredients would not be harmful to people, with exception for those individuals with specific food allergies.”

A letter was sent home to parents and school administrators spoke with the families of the students in that grade with known food allergies.

Faidley said so far, there have been no reported health outcomes.

A student, who did not want to be identified, says “I thought, wow, did I really eat dog treats? I was upset that our lunch aide, that we’re supposed to trust, who is supposed to take care of us, would do that to us.”

A parent, and former lunch aide, Lynn McGuckin says, “We weren’t allowed to hand anything out to the kids.”

A fifth grader asks the question on everyone’s mind, “Who gives children dog treats?”

Local authorities have been contacted and Faidley said the employee has been placed on administrative leave pending the outcome of the investigation.

The incident remains under investigation by the Boyertown Area School District.
