UPPER DEERFIELD TOWNSHIP, NJ —Horrified parents are speaking out and demanding answers from a South Jersey school district after a custodian was accused of contaminating cafeteria items and food with bleach, urine, and feces, according to multiple reports.

Giovanni Impellizzeri, 25, a school custodian in Upper Deerfield Township, faces multiple charges after authorities said he shared videos of himself “performing sexual acts with inanimate objects” around Elizabeth Moore School, officials said.

Authorities also accused Impellizzeri of contaminating food and cafeteria utensils with saliva, urine, feces, and bleach, according to the Cumberland County Prosecutor’s Office. Authorities said he wiped his penis, testicles and anus with slices of bread and also spit on bread before putting it back in the container to be served to students later.

Impellizzeri was charged last week with tampering with food products, aggravated assault and endangering the welfare of children. He was later charged with second-degree official misconduct.

In an interview with NJ Advance Media, parent Dawn Gilliard said she is outraged over the incidents and accused Upper Deerfield Township Schools of not being transparent with families.

“I feel like my kid who came home from school Monday not feeling well, how do I know that he didn’t eat the same bread that this man did these absurd things to?” Gilliard told NJ.com. “There’s a lot of unknowns. I’m just disgusted.”

According to Gilliard, parents received an automated call on Oct. 30, but she told NJ.com the message lacked information.

“When we got our original message on Monday, we were told that the subject had been apprehended and arrested but no children had been harmed,” she said. “That is the vague, robotic message. It wasn’t even a live person, it was a robotic message.”

An investigation into Impellizzeri began after the school received multiple anonymous tips about disturbing videos in a group chat on Telegram, an encrypted text messaging app, prosecutors said. Impellizzeri filmed the videos at work and shared his profession in various posts, according to an affidavit of probable cause.

Impellizzeri worked as a custodian for the district since Sept. 1, 2019. Authorities are still working to determine when the acts occurred, prosecutors said.

According to prosecutors, the school district has fully cooperated with authorities and worked with health officials to ensure the food products in question were discarded and all food-prep items, serving utensils and surfaces were properly sanitized.

Since parents were notified, more than 500 people have signed a Change.org petition calling for the resignation of Upper Deerfield Township Schools Superintendent Peter Koza.

“It is clear we have an absolute and complete failure of leadership at UDTS,” the petition reads. “Children potentially ingesting food contaminated by bodily fluids and bleach is certainly direct contact and the affected children are victims of a sex crime. Counselors and therapists should have been brought into the school.”

The petition continued, “Our children deserve support and parents deserve transparency. Instead, parents were met with false information and children were met with revictimization.”

In an update posted Monday, petition organizers said the district brought in a company to professionally clean Moore and also provided counselors to students. Additional cleaning was done at Seabrook and Woodruff schools last week, the petition said.

“This is a partial win for our children, our community, and our advocacy efforts,” the update read. “This is not something we should have had to fight for and the delay of this cleaning (over a week while children were still in the schools) is unacceptable.”

The school district did not immediately return Patch’s request for comment.

Following Impellizzeri’s arrest, the county health department recommended that individuals contact their healthcare provider if they suspect any illness.

The investigation remains open. Anyone with information related to the allegations can contact State Police Det. Alex Angerman at 856-451-0101. Tips can also be submitted online at CCPO.TIPS.
