A Barron County farm worker has been confirmed to have been infected with avian influenza, the state health department reported Friday. The confirmation was made by the federal Centers for Disease Control and Prevention (CDC).

With the CDC analysis in hand, “the case will now be reported as a confirmed human case” of the highly pathogenic avian influenza H5N1, the Wisconsin Department of Health Services (DHS) announced. It is the first reported case of the virus in a human in Wisconsin. 

The presumed infection was first reported Wednesday in a farm worker who was one of 19 people exposed to a poultry flock in Barron County where the avian flu virus was detected. The flock has been destroyed to prevent the spread of the virus. 

The individual has been treated with antiviral drugs and is recovering, according to DHS.

A farm worker in Barron County has tested positive for avian influenza after being exposed to a poultry flock infected with the virus, Wisconsin health officials said Wednesday. The woman is the first person identified with the infection in Wisconsin.

At the other end of the state, a case of the highly contagious disease has turned up in a Kenosha County poultry flock, according to the state agriculture department. The flock has been isolated and will be destroyed.

The risk of illness for the general public remains low, according to the Wisconsin Department of Health Services (DHS), while people working with infected animals or who might be otherwise exposed to them are at higher risk.

Also Wednesday, the federal government reported the first severe case of bird flu in a patient in Louisiana. That was believed to be associated with wild birds, not domestic poultry. 

The infected woman in Barron County was identified through a test at the Wisconsin State Lab of Hygiene. The diagnosis is pending confirmation at federal Centers for Disease Control and Prevention (CDC).

Reporting animal and bird illness

To report increased mortality or signs of illness among domestic birds, dairy cattle, or other animals, contact DATCP at (608) 224-4872 (business hours) or (800) 943-0003 (after hours and weekends).

She was exposed to the Barron County poultry flock where the state Department of Agriculture, Trade and Consumer Protection (DATCP) identified an infection with highly pathogenic avian influenza (HPAI H5N1) last week. The flock was destroyed.

After the infected flock was identified, DHS and Barron County Health and Human Services began monitoring farm workers who may have been exposed to the birds, said Thomas Haupt, a DHS research scientist and epidemiologist, in an online news conference Wednesday.

The woman who tested positive was one of two people tested. 

“She had relatively mild symptoms but symptoms that would be consistent with influenza, including sore throat, slight fever, some fatigue, some eye discharge,” said Haupt. He said she was improving after being treated with an antiviral medication and was expected to make a full recovery.

Public health officials are monitoring another 17 people who were exposed.

State public health veterinarian Dr. Angie Maxted said when people are infected with a communicable disease, public health agencies contact family and other household members to test them for the illness and inform them about preventive measures.

The Kenosha flock where an H5N1 infection was reported Wednesday is a “backyard flock” — one that is raised for a family’s own use, with limited, local sales of eggs or other products, said Dr. Darlene Konkle, DATCP state veterinarian. The flock consisted of 88 chickens and five ducks.

Haupt said the Kenosha County residents who might have been exposed are being tested for the virus. There are no concerns that members of the general public were at risk, however. Maxted said that it appears only the flock’s owners were exposed to the birds.

According to DATCP, the birds from the flock where the infection was reported will not enter the food supply.

In addition, poultry within a 10 kilometer (6.2 mile) area of the Kenosha flock will be restricted from being moved on or off any premises, said DATCP, which establishes a control area around any premises where an infection is found.  

DATCP has a mapping tool that poultry producers and owners can consult to learn whether their poultry are in an active control area or surveillance zone.

Concern about the virus has been heightened for the last three years, with reports of infections in both wild and domestic birds in North America since December 2021.

Konkle said DATCP has been sending information to dairy, poultry and other livestock producers all year, encouraging them to improve biosecurity measures to prevent the spread of disease and protect their birds and animals.

The H5N1 HPAI virus is highly contagious and can be fatal to domestic poultry. The severity of the illness varies depending on its strain and on which species of animal it affects, according to DATCP.

The virus spreads by contact with infected birds, commingling with wild birds or their droppings, and through clothing or equipment used by people working with infected birds or animals.

DHS has a web page with guidance for Protective Actions for People. The department can provide a limited amount of surplus personal protective equipment for farm workers, businesses and processors from the department’s medical stockpile through its Office of Preparedness and Emergency Health Care.  

State law requires all Wisconsin livestock owners to register where their animals are kept, which helps health officials alert flock and herd owners.

Avian flu in domestic birds tends to increase late in the year, likely due to weather conditions and the flow of migrating birds through Wisconsin. “There’s more opportunity, when it’s circulating in these wild birds” for the virus to spread, Konkle said.

People who have contact with livestock and animals are at higher risk for exposure to the H5N1 avian flu virus and should avoid contact with sick or ill animals, said Maxted.

When they must be in contact, people should follow “common sense” precautions, washing their hands frequently and wearing protective clothing including gloves, respiratory protection and eye protection, she said, and clothing exposed to animals should be cleaned and disinfected.

Haupt said the DHS bureau of environmental and occupational health has been working with farmers and farm workers to inform them about the risks of avian influenza and precautions to protect themselves from the virus. The agency urges people who do get sick to take time off.

“If someone is sick, if you don’t have to work — don’t work,” Haupt said. “Stay home, give yourself time to heal.”

This report has been updated to correct the number of people in Barron County being monitored after avian flu exposure.

WASHINGTON — A Louisiana resident has contracted the country’s first severe case of highly pathogenic avian influenza in a human, the Centers for Disease Control and Prevention announced Wednesday.

The unidentified person is believed to have been infected with the virus through sick or dead birds on their property that were not part of a commercial poultry flock, though federal public health officials declined to provide more details on a call with reporters, citing patient confidentiality. The virus is also called bird flu, or H5N1.

“Previously, the majority of cases of H5N1 in the United States presented with mild illness, such as conjunctivitis and mild respiratory symptoms, and fully recovered,” Demetre Daskalakis, director of the National Center for Immunization and Respiratory Diseases at the CDC, said during the call.

“Over the 20-plus years of global experience with this virus, H5 infection has previously been associated with severe illness in other countries, including illnesses that resulted in death in up to 50% of cases,” Daskalakis said. “The demonstrated potential for this virus to cause severe illness in people continues to highlight the importance of the joint, coordinated U.S. federal response, the One Health response, to address the current animal outbreaks in dairy cows and poultry and limit the potential of transmission of this virus to humans through animal contact.”

Despite the Louisiana case, Daskalakis said on the call, the CDC believes the threat to the general public remains low.

The Louisiana Department of Health wrote in a press release posted Friday that the person lives in the southwestern region of the state and was hospitalized, but didn’t provide additional information.

Emma Herrock, communications director for the Louisiana Department of Health, told States Newsroom in an email Wednesday the “patient is experiencing severe respiratory illness related to H5N1 infection and is currently hospitalized in critical condition.”

The patient, she said, “is reported to have underlying medical conditions and is over the age of 65.”

61 confirmed cases in humans

The CDC has confirmed 61 human cases of H5N1 throughout nine states this year, but the Louisiana patient is the first severe case of bird flu in someone within the United States. 

Daskalakis declined to say during the call why the Louisiana case is considered severe when a Missouri resident who was hospitalized due to bird flu was not classified the same way.

The Missouri patient, who was admitted to a hospital in August, had significant underlying medical conditions, according to public health officials. That person experienced “acute symptoms of chest pain, nausea, vomiting, diarrhea and weakness,” according to the CDC.

The CDC declined to say Wednesday what symptoms the Louisiana patient was experiencing, citing privacy concerns.

Bird flu has affected wild birds and poultry flocks throughout the United States for years, but it wasn’t until March that dairy cattle began becoming infected with the virus.

The dairy outbreak has affected 865 herds through 16 states this year, according to data from the U.S. Department of Agriculture. There have been 315 new cases in dairy cattle during the last month, with the vast majority of those diagnoses in California, while one herd each tested positive in Nevada and Texas.

Bird flu has affected nearly 124 million poultry throughout 49 states, according to USDA.

Milk testing

Eric Deeble, deputy under secretary for marketing and regulatory programs at USDA, said on the call the nationwide milk testing strategy launched earlier this month has expanded to several states.

The program requires anyone responsible for a dairy farm — such as a bulk milk transporter, bulk milk transfer station, or dairy processing facility — to share unpasteurized or raw milk samples when requested.

California, Colorado, Indiana, Maryland, Michigan, Mississippi, Montana, New York, Ohio, Oregon, Pennsylvania, Vermont and Washington are the 13 states currently enrolled in the program, he said.

In California, Gov. Gavin Newsom on Wednesday proclaimed a state of emergency “to further enhance the state’s preparedness & accelerate the ongoing cross-agency response efforts,” the governor’s press office said. 

“These states represent a geographically conversant list of states, some of which have been affected by H5N1 in dairy cows, and some of which have never detected the disease,” Deeble said. “Additionally, these first two groups of states represent eight of the top 15 dairy-producing states in the country, accounting for nearly 50% of U.S. dairy production. We anticipate continuing to enroll additional states in the coming weeks.”

The USDA also continues to have a voluntary bulk milk testing program for any farms planning to ship dairy cattle across state lines to provide an easier pathway to establishing the herd is negative for H5N1, instead of having to test each cow individually.  

DATCP finds case of avian flu on Barron Co. poultry farm

A case of avian influenza was identified in a Barron County commercial poultry flock, the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) said Thursday in a news release. 

The flock where the infection was found will be depopulated and none of those birds will be used for food, according to the release. A control area of 10 kilometers has been established around the farm, stopping the movement of any poultry within that radius.

“DATCP continues to urge all livestock owners to implement strong biosecurity measures to protect their flocks and herds from the disease,” the release states. “This includes washing hands, disinfecting equipment, restricting access to animals, and separating new additions to the flock or herd for at least 30 days. Poultry owners are asked, when possible, to keep their birds indoors.”

Avian flu, or H5N1, has circulated among wild and domesticated birds in North America since 2021, the release states. Other animals, including dairy cows, have also been infected. The virus has been transmitted to a number of humans across the country through raw milk from infected cows. 

Wisconsin has not identified any cases of the virus in the state’s dairy herds.

Pierce Co. town passes ordinance requiring factory farm permits

A Pierce County town of about 600 residents passed an ordinance requiring factory farms to obtain permits before moving into or expanding in the community. 

The decision follows a handful of other western Wisconsin communities in passing similar ordinances to limit the proliferation of concentrated animal feeding operations (CAFOs) in the region. Those other communities have faced legal challenges to their ordinances and one rescinded its regulation after a change in elected leadership. 

The town of Maiden Rock overlooks the Mississippi River’s Lake Pepin. On Monday, the town’s board unanimously passed the ordinance which will require any proposed CAFOs within the community to obtain a license to operate from the town board. When applying, CAFO operators must have a third-party engineer supply plan for how the farm will manage its waste, emissions and runoff.

Pierce County has seen increased expansion of factory farms this year, with a dairy in the town of Salem announcing plans to expand from 1,700 to 6,500 cows. 

Once an application is received, the ordinance requires the board to send a letter to all residents within a three mile radius of the proposed farm informing them of a public hearing. The board will be able to grant or deny the license and if granted, impose conditions on how the CAFO must operate. 

The ordinance also requires the CAFO to fund third-party enforcement of the permit conditions. 

In the board’s materials about the ordinance, the board highlighted the enforcement mechanisms, noting that state regulations surrounding CAFOs in the state largely rely on self-reporting to the state Department of Natural Resources — a system that has resulted in large manure spills going unreported. The materials also note that a pending lawsuit from the state’s largest business lobby is attempting to strip the DNR of its authority to regulate CAFOs. 

The ordinance was drafted by a commission appointed by the board to study CAFOs. At a public hearing on the ordinance, nearly 100 residents attended and all spoke in favor of its passage. The first 23 pages of the ordinance document outline the threats CAFOs can pose to a community’s groundwater, air quality, public health, local agricultural economy and infrastructure. 

“Our town is blessed with a stunning mix of farmland, woods and bluffs overlooking the Mississippi River’s Lake Pepin,” a fact sheet about the ordinance states. “Rush River, a Class 1 trout fishing destination, is sustained by cool spring-fed streams. Everyone relies on private wells for human and animal consumption. CAFOs with thousands of animals are proposing to spread thousands of truckloads of waste in the Town. State and county laws have almost no control over these huge facilities. Without an ordinance, their impact on roads, wells, health and the economy are unknown.”

Western Wisconsin advocacy group, Grassroots Organizing Western Wisconsin (GROWW) celebrated the ordinance’s passage, saying it’s a victory for communities standing up to protect themselves. 

“I think the town board heard loud and clear that the residents of the town wanted the ordinance,” Danny Akenson, a field organizer for GROWW, said in a statement. “It’s a result of the community banding together and sharing their stories and fears. We’ve heard it all. Landowners have had their land used for manure spreading without permission. Residents have had to call the Sheriff’s Department to escort them out of their own driveway due to heavy truck traffic on country roads. Families have had to live with poisoned water that causes sickness and cancer.”

“We know that one town standing up and protecting themselves isn’t enough,”  Akenson continued. “Everyone deserves to have access to clean water and safe roads. Across Wisconsin, whether you’re in Maiden Rock or Milwaukee, corporate greed gets in the way of that dream becoming reality. In 2025, we hope to see even more towns stand up and pass ordinances of their own.”

Several other communities in the region have passed similarly constructed ordinances and have faced opposition from industry groups. The town of Eureka in Polk County is currently fighting a lawsuit against its ordinance. A ruling in that case is expected in early January. 

The board’s fact sheet on the ordinance notes that at a state Senate hearing in March, a Wisconsin Farm Bureau representative testified that farm groups want the state government to preempt operations ordinances against CAFOs because state law currently allows them. 

Akenson told the Wisconsin Examiner that the ordinances are allowed under the state constitution. 

“Maiden Rock’s ordinance is backed up by both Wisconsin’s Constitution and our state statutes. We’re a state that values local control,” he said. “Corporate industry groups show up with lawsuits to try and bury small towns in legal costs and paperwork. Checks and balances threaten their profits and power to consolidate markets, and they hope to scare other communities from taking action.”

“In our view, that’s what’s happening in Eureka right now,” he added. “Despite these threats, more and more towns are taking steps to protect themselves by passing ordinances. People are tired of the intimidation tactics by industry representatives. The people on the ground in Pierce County and all across the state aren’t backing down.”
