A California farm is voluntarily recalling 90 cartons of chopped romaine because of the possible taint of Listeria monocytogenes, but no illness is reported. \"We are fully cooperating with the U.S. Food and Drug Administration and we are contacting all of our customers to ensure prompt removal of any product potentially associated with the recall,\" Steve Church of True Leaf Farms said in a statement. \"We are committed to conducting this recall quickly and efficiently to reduce any risk to public health.\" The recalled bags of romaine were packed in True Leaf Farms cardboard cartons and distributed by Church Brothers, LLC, and shipped from Sept. 12 to Sept. 13. All bags carry a \"use by date\" of 9/29/11. Produce affected by the recall was labeled as follows: 2# bags, chopped romaine - Bag and box code B256-46438-8. The chopped romaine was sent to an institutional food service distributor in Oregon who further distributed it to at least two additional states, Washington and Idaho. The FDA notified the farm that a sample taken as part of a random check from a single bag of chopped romaine tested positive for Listeria monocytogenes. Anyone who is in possession of the recalled romaine should not eat it, and should either destroy it or call 800-799-9475. Visit www.churchbrothers.com for updates.
