A food preservative that acts as an irritant when mixed with moisture was identified Saturday as the substance that caused 35 employees at a Mira Loma company to be hospitalized.
Ground ambulances and Riverside Transit Authority buses were used to transport 35 employees to a local hospital over the course of about five hours, the report stated.
Sodium benzoate was later identified as the substance.
No one was injured and losses remained at $0 as of Saturday morning, according to the report.
It remained unclear why the employees were taken to a hospital.
