A Wendy’s store in Dallas has been closed after a worker at the restaurant’s Dallas headquarters was found dead, company officials said Monday.
The cause of death was undetermined, but Wendy’s said it was not yet clear whether it was related to a health issue.
The Dallas County Medical Examiner’s Office said it received a death report on Thursday morning.
Wendy’s issued a statement Sunday saying that employees who work in the store “have been placed on administrative leave.”
The Dallas Morning News first reported the death of the worker at Wendy’s Dallas facility.
The chain said Monday that the worker was identified as the former manager of a Wendy’s facility in New Braunfels, Texas, and that he had worked for the franchise since August 2012.
Wendy Foods has about 700 restaurants in the U.S. and Canada.
The company said it had hired an outside investigator to review its operations and ensure that the store was safe.
The U.K.-based Wendy’s chain had said last month that it would close about 1,200 locations across the U., Canada and Europe in response to rising health risks.
In a statement, Wendy’s, which owns more than 20,000 restaurants in 31 countries, said it is “deeply saddened” by the news of the employee’s death.
“We have been working closely with local authorities and will continue to work closely with them in the coming days,” the statement said.
Wendy Foods said it would hold a “closed shop” in the Dallas area over the next several days.
The fast-food giant is expected to release an update later Monday on what steps the company is taking to ensure its restaurants are safe.
