Cleveland Beansprouts Co., Cleveland, has recalled alfalfa sprouts because of possible listeria contamination.

No lot codes or any other identifier are on the sprouts, which were distributed in Ohio, according to a company news release posted on the Food and Drug Administration’s website.

Calls to the Cleveland Beansprouts went directly to a voicemail system and were not immediately returned.

The notice is dated May 4, but it was not posted on the agency’s recall website until May 8.

A similar sprout recall that lacked lot codes or other traceable marking, also for a positive listeria test, was issued April 27 and expanded April 30 by Henry’s Farm Inc., Woodford, Va.
