The Leeds, Grenville and Lanark District Health Unit have announced that an outbreak of salmonella poisoning related to bean sprouts appears to be over. The announcement piggybacks on a similar announcement from Sheela Basrur, chief medical officer of health for Ontario.

Since Oct. 1, 648 cases of salmonella have been reported in Ontario, including two in the tri-county district that were linked to bean sprouts.

Three other cases being investigated came back negative for salmonella.

Close to 600 restaurants and retailers will not be permitted to serve raw or lightly cooked bean sprouts. Grocery stores may still sell raw bean sprouts for cooking, but they may not serve them on prepared salads in the deli area.
