Ruiz Foods suspended operations over the weekend at its Dinuba facility after food residue was found on a door, which failed to meet federal food safety and inspection standards.
The plant stopped production on Sunday at midnight. By Monday morning, the plant was cleared by authorities to resume operations.
The door was located in the food processing area and was removed, sanitized and re-installed, according to a company news release. To resume operations, Ruiz Foods provided the USDA with information about its maintenance programs.
About 850 employees were affected by the incident, a company spokesperson said. The company paid them for the unscheduled time off work.
Ruiz Foods makes products such as El Monterey taquitos and burritos, as well as other pre-made Mexican dishes such as tamales, chili rellenos and empanadas.
According to the company, there were no issues with contamination or food-borne illnesses.
Ruiz Food Products Inc. runs a 300,000-square-foot facility in Dinuba and employs about 3,000 people nationwide. The company also operates facilities in Tulare and Denison, Texas.
