A chemical spill at the POM Wonderful pomegranate juice plant in California has left 58 people in need of medical attention, with 11 hospitalized, the Fresno County Fire Department informed, ABC’s local affiliate reports.

About 150 employees were evacuated from the facility.

Employees in the area of the spill complained of difficulty breathing and dizziness.

The company said about a gallon (about 3.8 liters) of BioSide, a 15% peracetic acid cleaning solution, leaked from a small hole in a pipeline. POM Wonderful suspected that the damage was caused by equipment wear and tear, but this has not been definitively confirmed.

The workers were exposed to solvent fumes, the fire department said.

The chemicals, however, did not end up in the sewer or water bodies.

There was no danger to the public outside the plant.

The plant resumed operations a few hours later.
