(CNN) -  

The Food and Drug Administration is collaborating with the New York State Department of Health, the New York State Department of Agriculture and Markets and the Centers for Disease Control and Prevention to investigate an outbreak of 16 E. coli infections believed to be tied to a blend of organic spinach and spring mix sold at the Wegmans chain of supermarket.

Wegmans recalled 5-ounce and 11-ounce packages of Wegmans brand Organic Spinach & Spring Mix sold in its stores in New York, Pennsylvania, New Jersey, Virginia, Maryland and Massachusetts between Oct. 14 and Nov. 1. The recall was issued after New York State officials established a link between the product and reported illnesses in New York State due to E.coli O157:H7. State Garden, Inc. of Chelsea, Massachusetts provides the product to Wegmans.

The FDA is working with state officials, Wegmans, and State Garden, Inc. to determine further distribution of the product and ensure that it is removed from potential sale.

A statement by Wegmans counsels consumers to discard any remaining product at home and visit their service desk for a full refund. Wegmans Consumer Affairs can be contacted at 800-WEGMANS (934-6267), Monday through Friday, 8 a.m. to 5 p.m.
