More than 40 people have become ill after eating unpasteurized cheese curds produced by Wesley Lindquist of Highbridge, state health officials said Thursday.

Test results from six of those people confirmed the presence of Campylobacter jejuni bacteria, a statement from the Wisconsin Department of Health and Family Services said.

The bacteria cause nausea, diarrhea, abdominal cramping, fever and vomiting. On rare occasions, those affected develop more severe complications such as temporary arthritis or paralysis, generally after the initial symptoms have disappeared, the statement said.

State health officials urge anyone who has exhibited these symptoms and who has recently consumed unpasteurized milk or dairy products to contact their health care provider.

Anyone who has cheese curds produced by Lindquist, which are distributed in unlabeled clear bags, should contact the Ashland County-City Health Department so further testing can be done on the dairy product.

Lindquist has been ordered to stop production of the cheese curds, as well as all dairy manufacturing activity.

According to Donna Gilson, a spokeswoman for the state Department of Agriculture, Trade and Consumer Protection, the manufacturer was an "unlicensed cheesemaker using unlicensed facilities and unpasteurized milk" in what she called a "long-standing tradition" in Ashland County.

Food poisoning linked to cheese

State health officials are advising people to avoid eating unpasteurized cheese curds produced by Wesley Lindquist of Highbridge in Ashland County.

The cheese curds have been connected to an outbreak of campylobacter jejuni, a form of food poisoning. More than 40 people have become ill with symptoms including nausea, diarrhea, bloody diarrhea, abdominal cramping, fever and vomiting after eating the unpasteurized white cheese curds. Most started to become ill between May 24 and June 2.

People experiencing these symptoms who recently consumed unpasteurized milk or dairy products should contact their health care providers and notify the Ashland County Health Department. It is illegal to sell or distribute unpasteurized dairy products in Wisconsin.

Raw milk and cheeses: health risks are still black and white

National Center for Infectious Diseases

Each year, people become ill from drinking raw milk and eating foods made from raw dairy products. Unlike most of the milk, cheese, and dairy products sold in the United States, raw milk and raw dairy products have not been heat treated or pasteurized to kill germs. Although many states outlaw the sale of these items, many people including dairy producers, farm workers and their families, and some ethnic groups continue to drink raw milk and eat foods made from raw dairy products. Several types of raw cheeses such as feta, brie, queso fresco, sheep's and goat's milk cheese have been illegally sold in the United States.

Germs in These Products Cause Thousands of Illnesses

Raw milk and raw dairy products may carry many types of disease-causing germs such as Campylobacter, Escherichia coli, Listeria, Salmonella, Yersinia, and Brucella. When raw milk or raw milk products become contaminated, people who eat the contaminated foods can get sick. Here are a few examples of outbreaks that have been reported since 2000:

2001: Outbreak of Campylobacter jejuni infections from drinking "raw" or unpasteurized milk.

2003: Outbreak of Listeria monocytogenes infections from eating unpasteurized queso fresco (a Mexican-style soft cheese)

2003: Outbreak of Salmonella infections from eating unpasteurized queso fresco.

2004: Outbreak of E. coli.O157 infections from eating unpasteurized queso fresco

These Illnesses Can Be Dangerous

Getting sick from one of these germs can lead to diarrhea, stomach cramps, fever, headache, vomiting, or exhaustion. The misery typically lasts anywhere from several hours to a week or more but most healthy people will recover.

These illnesses can be dangerous for people with weakened immune systems, such as the elderly, children, and people with cancer, an organ transplant, or HIV/AIDS. Germs found in raw milk and raw dairy products can be especially dangerous to pregnant women and their unborn babies.

Pasteurization Is Key to Making Dairy Products Safe

Heat-treating milk to kill germs is called pasteurization . Using heat to pasteurize milk was first suggested in the late 1800's as a way to decrease the amount of a germ that causes tuberculosis. Today, pasteurization is still our main protection from germs carried in milk and cheese.

Pasteurization is a simple process. In the United States, raw milk is collected from cows and heated to a high temperature for a short period of time. This destroys any harmful germs that may be contaminating the milk. After it is pasteurized, milk and products made from milk are safe for human consumption. Pasteurization does not harm the nutritional value of milk and cheese.

Playing It Safe

When shopping for milk or cheese, play it safe. Carefully read food labels to make sure a product is pasteurized. Purchase only products that are pasteurized or made from pasteurized milk.

These people should always avoid raw milk or raw dairy products:

Pregnant women or women considering pregnancy

Children under 5 years of age

The elderly

Persons infected with HIV

Persons with cancer

Anyone who is immunocompromised (such as persons with organ transplants)

Health officials investigate suspected outbreak of Campylobacter

County has 13 possible cases of bacterial illness

Ashland County and state public health officials are investigating an outbreak of a diarrheal illness that is possibly related to an unpasteurized dairy product.

According to Ashland County Health Officer Terry Kramolis, one person has been confirmed with an infection by the Campylobacter bacteria, which can cause nausea, diarrhea, abdominal cramping and occasional vomiting. On rare occasions, the illness has more severe complications such as temporary arthritis or paralysis, generally after the initial symptoms have disappeared.

"Currently, 13 people from Ashland County have probable Campylobacter infections," Kramolis said. "And several people have been hospitalized.

Stool samples from several affected individuals are being confirmed for Campylobacter at the Wisconsin State Laboratory of Hygiene in Madison. The Wisconsin Department of Agriculture, Trade and Consumer Protection Laboratory is also conducting tests on food products recently eaten by ill individuals."

Kramolis declined to identify the suspect food items until investigations are complete, but said steps had been taken to ensure no other persons would be at risk from those products.

"We don't want to release that information right away because it might bias the interviews we are doing," she said.

Kramolis said when the investigations are completed, the source of the possible infections would be made public. She emphasized that the suspected source of the infections has been isolated and is no longer considered to be a further threat to the public.

Campylobacter infections are frequently associated with the consumption of unpasteurized milk or dairy products. The illness is not generally contagious person-to-person but could potentially be spread by persons working in food service or at a daycare facility who did not use good hand-washing practices.

"There is no risk to the public through a continued communicable disease state," she said.

Health officials are urging anyone who is exhibiting symptoms consistent with Campylobacter and have recently consumed unpasteurized milk or dairy products to contact their health care provider for diagnosis and confirmation of the illness. She also said anyone who has recently consumed unpasteurized milk or dairy products and still has the products available for testing, either opened or unopened, should contact the local health department for directions.

"Because of the health risk of Campylobacter infections, consumption of unpasteurized milk and dairy products is discouraged," Kramolis said.

Consuming raw or undercooked poultry, or exposure to farm animals, puppies or kittens with diarrheal illness may also cause the infection, she said.

The Ashland County Health Department, the Wisconsin Department of Health and Family Services' Division of Public Health and the Wisconsin Department of Agriculture, Trade and Consumer Protection are collaborating in the investigation, Kramolis said.

"What we are doing at the state level is DNA fingerprinting, trying to match all these people to see if it is the same source," she said.

"If you recently consumed any unpasteurized dairy products and have the above symptoms, please see a physician and contact your local health department," she said. "It is important that your physician collect a stool sample before treating with antibiotics in order to confirm the diagnosis."

Kramolis said the investigation was still ongoing, and that none of the cases of suspected infection in Ashland County were life threatening.

Nevertheless, she said Campylobacter infections were a serious matter.

"It is very incapacitating if you get this," she said. "If you get this, you are very sick. You definitely know you've got something."

Kramolis said the disease was a special risk for the very young, the elderly or those with other health issues.

"Those people need to be careful," she said.

She said the department was educating the people they were talking to about Campylobacter.

"We are also doing everything we can to make notification to all of our medical facilities and our clinics. Right now we are at an investigational level, trying to determine the exact source," she said. "We feel we have a handle on it."

Kramolis said while rare, Campylobacter infections were not unknown in Ashland County.

"Typically we will see some cases in the summer anyway. In my county I might see one or two cases annually. So for me this is a major event, she said. "I don't know where our numbers are going to be when we are done. I wouldn't be causing this alert if I didn't have great concern."

Kramolis said persons with additional questions, or who suspect they or someone they know may have been infected, should call her at the Ashland health Department at (715) 682-7028.

Bacterial illness linked to raw milk infecting more people

Since the first of the year, the Yakima Health District has seen a spike in the number of cases of a bacterial infection that causes stomach sickness.

Many of the 41 cases of campylobacteriosis so far this year might be tied to the consumption of unpasteurized milk and related cheese products, said Marianne Patnode, Communicable Disease Services coordinator at the health district.

By this time last year, only 21 people had reported having the bacterial illness characterized by diarrhea, cramping, abdominal pain and fever. Symptoms usually appear within two to five days of exposure to the organism and usually last about one week, according to the Centers for Disease Control and Prevention. In very rare cases it can be life-threatening, but it is not transmittable from person to person.

Campylobacteriosis is one of the most common types of diarrheal illnesses in the United States. While unpasteurized milk products are one potential source of campylobacter infections, consuming and handling raw or undercooked poultry or drinking contaminated water are other common causes.

The reported cases have involved people of all ages and races from across the county, but most of those associated with unpasteurized milk products have been in the lower Yakima Valley, Patnode said.

To avoid campylobacter infections, the CDC advises people not to consume unpasteurized milk, which is lawful to sell in Washington though illegal in 22 other states. People should also be sure to cook poultry thoroughly, wash hands after handling animals, avoid drinking contaminated water and wash kitchen utensils that come in contact with raw meat with hot soapy water, according to the CDC's Web site.
