An Indiana dairy company said Thursday that it is recalling a small amount of blue cheese because it could be contaminated with listeria, adding to the growing number of products recently affected by the deadly bacteria.

Fair Oaks Dairy Products LLC is recalling about 20 pounds of Fair Oaks Royal Blue Cheese sold to consumers in Indiana, Illinois, Michigan and Ohio. The company said the recall was ordered after its own testing detected listeria.

The federal Centers for Disease Control and Prevention on Thursday notified the Missouri Department of Health and Senior Services (DHSS) of one additional confirmed case of listeriosis in Missouri associated with the national recall of cantaloupe produced by Jensen Farms, of Holly, Colo.

A total of six listeriosis cases in Missouri have been confirmed by the CDC as linked to the recalled cantaloupe. The latest case is the second to occur in the Southwest District. The individual, age 84, died. According local medical officials, the immediate cause of death was sepsis with listeriosis as a contributing factor.

The other cases include three in the Northwest District, one in the Eastern and two in the Southwest District. All six cases were hospitalized. On September 21, DHSS reported one individual, age 94, died. According to local medical officials, the immediate cause of death of the 94-year-old person was not the listeriosis infection.

A Montgomery County woman has been diagnosed with the first reported case of listeriosis, associated with the recent outbreak linked to cantaloupe in Colorado.

According to Montgomery County Health Department, an elderly woman from the Collegeville area became ill early last month. She was hospitalized and has since recovered, but cantaloupe recovered from her property tested negative for listeria. Currently, 123 cases of listeria infections have been reported in 26 states. Listeria infections are most susceptible in children and the elderly. Symptoms, which typically last between seven and 10 days, include fever, headache, muscle aches, nausea, abdominal pain and diarrhea. It is triggered by a bacterial infection and afflicts individuals more often with a deficient immune system. Collegeville’s is the state’s first case linked to the outbreak from a Granada, Colo. cantaloupe farm. The fruit in question is sold under the name Rocky Ford cantaloupes and consumers are advised to steer clear of them. Public health officials have continued to collaborate with the U.S. Food and Drug Administration (FDA) in determining the extent of the distribution of the contaminated products.

The Wyoming Department of Health says it has confirmed a fourth case of listeria-related illness in the state but is still researching whether it’s associated with tainted cantaloupe.

Health Department spokeswoman Kim Deti said Wednesday that an elderly man in Lincoln County has been diagnosed recently as Wyoming’s fourth recent case of listeriosis.

A Sheridan woman has died and a man and woman from Laramie County have been sickened by the disease in recent weeks. Deti says the Lincoln County man is still alive and authorities are looking into how he contracted the disease.

Health officials say the death of an elderly woman in western New York is the second in the state linked to listeria-tainted cantaloupes.

The Genesee County Public Health Department says the death of the unidentified woman with underlying health conditions was connected to the cantaloupes.

The Democrat and Chronicle of Rochester reports that the woman died several weeks ago. The woman had been hospitalized, but was not initially diagnosed with listeriosis.

• As of 9am EDT on October 17, 2011, a total of 123 persons infected with any of the four outbreak-associated strains of Listeria monocytogenes have been reported to CDC from 26 states. Pennsylvania has reported their first case since the last CDC update.  The number of infected persons identified in each state is as follows: Alabama (1), Arkansas (1), California (2), Colorado (36), Idaho (1), Illinois (2), Indiana (3), Iowa (1), Kansas (7), Louisiana (2), Maryland (1), Missouri (4), Montana (1), Nebraska (6), New Mexico (13), New York (2), North Dakota (1), Oklahoma (11), Oregon (1), Pennsylvania (1), South Dakota (1), Texas (18), Virginia (1), West Virginia (1), Wisconsin (2), and Wyoming (3). Pennsylvania has reported their first case since the last CDC update.

• Twenty-five deaths have been reported: 6 in Colorado, 1 in Indiana, 2 in Kansas, 2 in Louisiana, 1 in Maryland, 1 in Missouri, 1 in Nebraska, 5 in New Mexico, 2 in New York, 1 in Oklahoma, 2 in Texas, and 1 in Wyoming. Among persons who died, ages range from 48 to 96 years, with a median age of 87 years. In addition, one woman pregnant at the time of illness had a miscarriage.

• CDC recommends that consumers not eat whole or pre-cut Rocky Ford-brand cantaloupe from Jensen Farms. This is especially important for older adults, persons with weakened immune systems, and pregnant women.

• Even if some of the cantaloupe has been eaten without becoming ill, dispose of the rest of the cantaloupe immediately. Listeria bacteria can grow in the cantaloupe at room and refrigerator temperatures.

• Cantaloupes that are known to NOT have come from Jensen Farms are safe to eat. If consumers are uncertain about the source of a cantaloupe for purchase, they should ask the grocery store. A cantaloupe purchased from an unknown source should be discarded: “when in doubt, throw it out.”

South Dakota’s lone reported case of listeria during a nationwide outbreak is in Minnehaha County.

State Health Department Epidemiologist Lon Kightlinger tells the Argus Leader that the woman who got sick is in her 60s and is hospitalized. He says officials have not been able to determine whether she ate cantaloupe before becoming ill.

Federal officials say an outbreak of listeria in cantaloupe is now linked to 116 illnesses and 23 deaths nationwide, making it the deadliest known outbreak of foodborne illness in the U.S. in a quarter century.

The tainted cantaloupe should be off store shelves by now. At least one South Dakota retailer sold cantaloupe from the Colorado farm linked to the listeria outbreak, but the melons were taken off store shelves Sept. 12.
