OK Food, Inc. has recalled about 933,272 pounds of breaded chicken products out of concern that it is contaminated by metal and other extraneous materials, according to the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS).
The issue came to light on March 21 after five customers complained that they found metal objects in the breaded chicken products, the FSIS said. An internal investigation found that the metal objects came from metal conveyor belting.
FSIS said there have been no confirmed reports of “adverse reactions” and urged consumers to throw away or return the product.
