Lancaster Foods LLC, of Jessup, Maryland, recalled 10-ounce packages of Krisp-Pak Ready to Eat Hydro-Cooled Fresh Spinach yesterday after tests by the North Carolina Department of Agriculture and Consumer Services confirmed the presence of Listeria monocytogenes in product samples.

The packages have the code: “Best Enjoyed By: 23 Jun 10, Product of USA, 10/158/09:17/1/05.”

State inspectors collected the product from a Farm Fresh store in Elizabeth City.

No illnesses associated with this product have been reported.

The Lancaster Foods recall occurred the same day that the Center for Produce Safety at the University of California, Davis began its Produce Research Symposium.  The first day of the symposium offered presentations and discussion by leaders in academia and industry on a variety of topics, from flies as vectors for the spread of E. coli O157:H7 in leafy greens to the internalization and survivability of E. coli O157 on spinach in field production environments.
