The Buffalo News reports that a Tyson meat processing plant on Perry Street has been shut down by federal regulators after inspectors found violations during follow-up testing stemming from an August recall of deli meat produced at the Buffalo facility.

The plant suspended operations Tuesday after an inspection by the U. S. Department of Agriculture’s Food Safety and Inspection Service, the federal agency said Wednesday.

The shutdown was triggered by the results of sampling that the federal inspectors conducted during a food safety assessment, the agency said. That assessment was linked to the USDA’s activities at the Perry Street plant since the deli meat recall, said Gary Mickelson, a Tyson spokesman.

The plant employs 560 workers. About 480 workers are affected by what Mickelson described as a “temporary suspension of operations.”

In August, about 380,000 pounds of deli meat produced at the plant and sold at Walmart was voluntarily recalled after a sample tested positive for Listeria monocytogenes.

The plant had two similar recalls in 2004. Tyson first voluntarily recalled 442 pounds of cooked ham in August 2004 after a sample tested positive for Listeria. In November 2004, the company recalled another 50,000 pounds of hot dogs, prompted by an unspecified customer complaint. There were no reports of consumer illnesses in either case.
