(NEXSTAR) – Deli products sold at Kroger supermarkets have been recalled amid concerns over possible contamination with Listeria monocytogenes.

The recall affects Basil Pesto Bowtie Salads and Smoked Mozzarella Penne Salads, according to a company announcement issued over the weekend. The products were sold at deli-counters, by weight, and also in prepackaged portions at self-service cases in 1,860 stores across 28 states, Kroger said.

Kroger initiated the recall earlier this month after being informed by a supplier that the pasta within the salads — which was provided to the supplier by third company, identified as Nate’s Fine Foods of Roseville, California — may have been contaminated, according to the recall alert.
