More than a dozen salads and salad kits sold at multiple retailers in six states are being recalled over possible listeria contamination.

Revolution Farms, based in Michigan, initiated the recall after testing of a random sample returned a positive result for Listeria monocytogenes.

The recalled products were shipped to retailers and distributors in Michigan, Ohio, Indiana, Illinois, Kentucky and Wisconsin. Over a dozen of these outlets, including Fresh Market, Meijer and SpartanNash, are listed as recipients in the recall notice.

Each of the products features the Revolution brand name, according to the notice. They were also packaged between March 3 and March 11,
