The Albert Gallatin School District is alerting parents and families that the shaved ice served at a school event on Wednesday may have been contaminated with broken glass and insulin. 

In a notice to parents and families shared on the district's social media page, Superintendent Christopher Pegg said the potentially contaminated ice was served at a trunk or treat event at the A.L. Wilson Elementary Center. 

The district is now advising anyone who consumed shaved ice at the event and might be experiencing adverse affects to seek medical attention. 

"Please contact the school or Albert Gallatin business office to notify us if you or your child have had any ill effects as a result of consuming the shaved ice," Pegg said. 

"We were surprised, but I think the school district did everything they should," said Robert Leighty, a parent. "They sent out information as soon as possible. I have no problem with how the school district's handling everything." 

The business, "Have An Ice Day," was serving shaved ice, and the owner, Mark Howard, said it was a complete accident. He said that his dog's insulin somehow got into the machine, and once he realized that, he stopped service and alerted everyone immediately. 

Howard told KDKA-TV that he has been cooperating and is speaking with his attorney before making any more comments. 

"I assume it was an accident, I assume, as soon as he found out, he told somebody," added Leighty. "It is what it is, at least he told somebody, accidents happen."

"I'm just glad that he caught it, that he was even aware of it, that's a plus," said Karin Goal, a grandparent. "We're all human, things happen, accidents happen, but it's very unfortunate [that it happened to] grade school kids." 

So far, there have been no reports of anyone getting sick. The district said state police will determine if any charges are appropriate. 

According to the American Diabetes Association, insulin must be injected into the skin for it to get into the bloodstream.
