The Massachusetts Department of Public Health is warning people not to consume any Chang Farm-brand soy sprouts because of possible contamination.

The agency said the sprouts, produced by Chang Farms of Whatley Mass., might be contaminated by a bacteria, Listeria monocytogenes, that can produce severe illness.

The affected product is packaged in 12-ounce plastic bags, with a "Sell By" date of April 19, 2008. The spouts were distributed to retail stores in Massachusetts.

Consumers with questions about the warning can contact the state's Department of Public Health at 617-983-6712.
