ALBUQUERQUE, N.M. (KRQE) – If you’ve eaten at Dion’s recently, the U.S. Department of Agriculture is issuing a public health alert.

The USDA has concerns that assorted sliced deli meat products served to customers may be contaminated with listeria.

The products were produced by Peter DeFries Corporation in Albuquerque.

The sliced roast beef, pastrami, and turkey items were first produced December 14 but may have been sold as late as January 4.

They were used on pizza, salads, and open-faced sandwiches.

The potential problem was discovered during routine internal testing of equipment, according to a news release by Dion’s.

The company said that no food products tested positive for contamination and that there have been no confirmed reports of illness or adverse reactions.

“Food safety is our number one priority. We are currently serving safe, high-quality pre-sliced products from our normal vendors. We are working with our partners at the USDA to resume our in-house deli meat slicing operation,” Mark Herman, CEO of Dion’s, said, in a news release.

The USDA says to throw out all leftovers.

The Peter DeFries Corporation has set up a hotline at (505) 515-2660 and it is open daily from 8 a.m. to 8 p.m.
