Highly pathogenic avian flu found in Racine County
Ryan Patterson
RACINE — A case of contagious bird flu has been found in Racine County.
The Wisconsin Department of Agriculture, Trade and Consumer Protection said it identified a case of highly pathogenic avian influenza in a backyard flock of poultry in Racine County.
The birds were depopulated and will not enter the food system, according to a news release.
Highly pathogenic avian influenza viruses are contagious and often result in the death of domestic poultry, according to the release.
The HPAI, which has been in wild and domestic North American birds since December 2021, is caused by influenza type A viruses and can be spread by contact with infected birds.
Livestock owners are encouraged to implement strong biosecurity measures to protect their animals from HPAI, including washing hands, disinfecting equipment, restricting access to animals, separating new animal additions for at least 30 days and keeping their birds inside when possible.
To report increased mortality or signs of illness among domestic birds, dairy cattle, or other animals, follow the instructions at datcp.wi.gov/Pages/Programs_Services/AnimalDiseases.aspx.
When poultry are diagnosed with HPAI, risk factors are evaluated and a 10-kilometer surveillance zone might be implemented, without movement restrictions for surrounding poultry flocks, according to the release.
To help determine if poultry are in an active control area or surveillance zone, poultry owners are encouraged to use DATCP’s online mapping tool at widatcp.maps.arcgis.com/apps/webappviewer/index.html?id=41c12066a88043288d7ca51abf8fa641.
DATCP urged Wisconsin livestock owners to register their premises, as registration helps officials communicate with flock and herd owners during disease outbreaks.

HPAI also has affected other species, including dairy cattle.

Yin, one of the Milwaukee County Zoo's Chinese alligators, has died
Hannah Kirby
A Yang without his Yin. The Milwaukee County Zoo is mourning the loss of another one of its animals.
Chinese alligator Yin, a longtime resident, was humanely euthanized in early May, the zoo shared in a Tuesday, May 19, post on its website and social media. She is suspected to have had ovarian cancer with metastasis, the zoo shared, citing preliminary necropsy results.
"Yin was a favorite among zookeepers and will be missed," the post said. "She was very smart and slower to trust but comfortable once she knew the animal care team members. The zookeepers noted she was strong-willed and intelligent, and loved shrimp."
When the animal care team noticed Yin was having mobility issues last June, the veterinary staff assessed her, which lead to antibiotic treatment for a spinal lesion, the post said. More recently, Yin's skin condition and appetite have been declining.
"After much consideration about her quality of life, along with a poor prognosis, the team made the decision to humanely euthanize her," the post said.
Yin was nearly 41 years old. The median life expectancy for a Chinese alligator in human care in 26 years old, according to the zoo.
Yin and male Chinese alligator Yang, 39, have been behind the scenes since Yin's treatment began, with Yang providing companionship to her, the post said.
"In the morning, Yin and Yang were often seen laying closely, and they spent a lot of time together," the post said.
Yin and Yang came to Milwaukee together from the Bronx Zoo in 1995.
Yang – who zookeepers note is healthy – will return to the Chinese alligator habitat, located in the zoo's Aquatic & Reptile Center, once ongoing pool renovations to the habitat are completed, the post said.
The zoo has been in contact with the Association of Zoos and Aquariums Species Survival Plan Program coordinator, the post said, and Milwaukee will likely receive a recommendation for another female in the future.
Yin's death comes just around a month after another longtime zoo resident, Brittany – a 45-year-old African savanna elephant – was humanely euthanized after her health declined. In September, one of the zoo's other beloved geriatric elephants, Ruth, was euthanized after a couple of falls.
