At least 52 people were rushed to local hospitals Friday afternoon after a hazmat incident sickened dozens of people at a medical packaging company in southeast Pennsylvania.

Lt. Pete Nickischer, from the Upper Macungie Township Police Department in Lehigh County, said authorities received reports of a chemical smell in the building and some employees experiencing nausea, vomiting, and headaches.

According to Nickischer, Fire, EMS and police crews were called to the scene at Sharp Corporation, a pharmaceutical packing company, on Keebler Way around noon.

Lehigh County Special Operations assisted crews at the scene, Nickischer said.

Hazmat crews are still working to determine what sickened the employees, he added.

Lehigh Valley Health Network received about 30 patients at two of its hospitals, according to spokesperson Brian Downs. He told The Post that some patients presented with minor symptoms such as headaches and were still being monitored and undergoing tests.

“They weren’t all with symptoms,” he said.

“Some were complaining they had headaches or hoarse voice.”

St. Luke’s University Health Network spokesperson Sam Kennedy said 22 people were taken to its Allentown hospital. All are stable and will be discharged, he told local media.

The building where the incident occurred has since been cleared by authorities who are now allowing people to re-enter.

Nickischer told WFMZ the cause had not yet been determined.
