Sprouts processed by a Connecticut-based company have been recalled after a sample in New York City tested positive for the bacterium Listeria monocytogenes, which can cause serious and sometimes fatal infections in vulnerable people, the Hartford Courant reported Friday.

The sprouts, from Bridgeport's Amalgamated Produce Inc., were sold at Stop & Shop, ShopRite and Price Chopper stores in Connecticut, the newspaper said. As of Thursday, no illnesses had been reported in the state, the Courant said.

Sold under various brand names, the sprouts have a "sell by" date of March 31 through April 27, and are packaged in 4-ounce plastic containers, the Courant reported. Also recalled were 8-ounce Nature's Promise organic alfalfa sprouts and 5-pound bags of alfalfa sprouts, the newspaper said.

Consumers who bought the sprouts should discard the packages or return them to the place of purchase for a refund, Connecticut Commissioner of Consumer Protection Jerry Farrell Jr. told the Courant.
