Wyoming health officials have identified two more listeria cases, including one where the patient died.
Wyoming Department of Health officials believe each Wyoming case is associated with an ongoing multistate cantaloupe-related outbreak. One of the three has been connected by lab testing. Results are pending on the other two cases.
The newly reported cases include a Sheridan County woman who has died and a Laramie County woman.
Dr. Tracy Murphy, state epidemiologist, noted both individuals had risk factors and underlying conditions known to place people at higher risk for listeria illness.
Investigative efforts have linked the outbreak to "Rocky Ford" cantaloupe from Jensen Farms of Granada, Colo.
"Wyoming residents should not eat cantaloupe shipped from this farm," Murphy said.
A Kansas food processor known as Carol's Cuts has also issued a recall notice for its fresh-cut cantaloupe products from fruit grown at Jensen Farms.
"It may be hard to tell if a particular cantaloupe is affected," Murphy said. "If you're not sure it is safe, don't take any chances. For some people, listeriosis can be severe and even deadly."
Listeriosis is a rare and serious illness caused by eating food contaminated with bacteria called listeria. A person with listeriosis usually has fever and muscle aches. Persons who think they might have become ill should consult their doctor.
Murphy noted that it can be several weeks -- up to two months -- before listeria symptoms develop in a person who eats the contaminated food.
Listeria can be fatal, especially in certain high-risk groups such as older adults, people with compromised immune systems and certain chronic medical conditions, unborn babies and newborns. In pregnant women, listeriosis can cause miscarriage, stillbirth, and serious illness or death in newborn babies.
