NEW YORK (PIX11) – Avian Influenza, commonly called bird flu, has been detected in New York City according to one study.

“A very small number of birds were found positive,” the study conducted with Mount Sinai and the Icahn School of Medicine at Mount Sinai’s Institutional Animal Care and Use Committee reads. “The presence of the virus poses a low but non-zero risk for humans and pets, more awareness about the presence of this virus in the urban animal-human interface is needed.”

A bird flu outbreak was first detected in the U.S. at the beginning of the month at a facility in Texas. Since then, two human cases have been reported in the U.S. but neither were fatal.
In both cases, flu-like symptoms and red eyes were reported, officials stated.

Since the detection of the first case of bird flu in Texas, there have been no reports of a human infected with bird flu in the tri-state area. There is also no evidence that person-to-person contact can spread Avian flu, according to officials... https://pix11.com/news/local-news/st...ound-positive/

maybe reffering to Colorado?

.....Meanwhile, the number of dairy herds in previously affected states continue to grow, with the total now at 21. Among other recent detections, Michigan now has a second positive herd, along with more detections on farms in Texas and New Mexico.... https://www.cidrap.umn.edu/avian-inf...ina-dairy-herd

Maryland Department of Agriculture Issues Order Restricting Movement of Dairy Cattle Into the State

April 10, 2024


Maryland Farmers Encouraged to Continue Biosecurity Practices

ANNAPOLIS, MD (April 10, 2024) – The Maryland Department of Agriculture today issued an order restricting movement of dairy cattle into Maryland from states with confirmed outbreaks of Highly Pathogenic Avian Influenza (HPAI) in their herds.

Last week, USDA announced detections of HPAI in dairy cattle herds in several states including Texas, Kansas, Michigan, Idaho, Ohio, North Carolina and New Mexico following increased illness and lower milk production rates among herds. USDA National Veterinary Laboratory Services confirmed the strain is H5N1, which has been circulating in the wild bird population for the last several years and appears to have been introduced to these herds by wild birds.

Although there have been no detections of HPAI in cattle in Maryland, producers are reminded to practice strong biosecurity. Cattle owners should minimize animal movements and isolate sick cattle. New animals should be quarantined for a minimum of two weeks before introducing them to an established herd.

“Maryland is home to a robust dairy and cattle genetics industry. The Maryland Department of Agriculture, in collaboration with state and federal partners, is actively monitoring and responding to this situation,” said Maryland Agriculture Secretary Kevin Atticks. “This order acts as another layer of protection for our Maryland farmers and ag industry partners.”

Highly Pathogenic Avian Influenza Detected in South Dakota Dairy Herd

PIERRE, S.D. – The South Dakota Department of Agriculture (DANR) and the Animal Industry Board (AIB) have received confirmation from the United States Department of Agriculture’s (USDA) National Veterinary Services Laboratory (NVSL) of the detection of highly pathogenic avian influenza in a dairy cattle herd in South Dakota. This is the first confirmed case of HPAI in a dairy farm in South Dakota.

“South Dakota Dairy Producers encourages all dairy producers to closely monitor their herd and contact their herd veterinarian immediately if cattle appear symptomatic,” said Marv Post, Chairman of South Dakota Dairy Producers. “USDA continues to emphasize that pasteurization kills the virus and that milk and dairy products are safe to consume.”

Symptoms are mostly restricted to late-stage lactating cows and include a drop in milk production, loss of appetite, and changes in manure consistency. Producers are encouraged to practice good biosecurity on their farms such as limiting visitors and excluding any wild birds or animals from the dairy.

Dairies are required to ensure only milk from healthy animals enter the food supply chain. Additionally, the pasteurization process of heating milk to a high temperature ensures milk and dairy products can be safely consumed, as confirmed by the Centers for Disease Control (CDC). At this stage, there is no concern about the safety of the commercial milk supply or risk to consumer health. In line with long-standing policy, the CDC does not recommend consuming unpasteurized milk or raw milk. Pasteurization has continually proven to successfully inactivate bacteria and viruses, like influenza, in milk.

USDA, Food and Drug Administration (FDA) and Centers for Disease Control and Prevention (CDC), as well as state veterinary and public health officials, continue to investigate the emerging illness among dairy cows that is causing decreased lactation, low appetite, and other symptoms.

DOH Secretary, Melissa Magstadt, Issues the Following Statement on H5N1 Avian Influenza

Date published: 04/12/2024



For Immediate Release: April 12, 2024
Contact: Tia Kafka -DOHMedia@state.sd.us

Department of Health Secretary, Melissa Magstadt, Issues the Following Statement on H5N1 Avian Influenza

PIERRE, SD - In response to recent concerns surrounding H5N1 Avian Influenza, South Dakota Department of Health Secretary, Melissa Magstadt, underscores collaborative efforts with the Department of Agriculture and Natural Resources to safeguard the well-being of both the state's population and livestock.

“The Department of Health is working with the Department of Agriculture and Natural Resources to ensure the safety of the people and livestock in South Dakota. It’s important to note that the risk of human infection is low,” said Department of Health Secretary, Melissa Magstadt. “If you have had exposure to an H5N1-infected bird or animal and are showing signs and symptoms of infection, such as redness and swelling of the eye (conjunctivitis), cough, fever, or sore throat, visit your medical provider to be tested.”

Currently, there is no concern about the safety of the commercial milk supply or risk to consumer health. Dairies are required to ensure only milk from healthy animals enter the food supply chain. Additionally, the pasteurization process of heating milk to a high temperature ensures milk and dairy products can be safely consumed, as confirmed by the Centers for Disease Control (CDC). In line with long-standing policy, the CDC does not recommend consuming unpasteurized milk or raw milk. Pasteurization has continually proven to successfully inactivate bacteria and viruses, like influenza, in milk.

For more information, please see the H5N1 Avian Influenza page on the DOH website.

At the heart of the Department of Health’s mission is a simple goal: to protect and improve the health of all South Dakotans. The department is entrusted with the vital task of promoting wellness, preventing disease, and ensuring access to quality healthcare for all South Dakotans.

Highly Pathogenic Avian Influenza Detected in Three New Michigan Dairy Herds

April 12, 2024



LANSING, MI – Today, Michigan Department of Agriculture and Rural Development (MDARD) Director Tim Boring announced the detection of highly pathogenic avian influenza (HPAI) in dairy herds in three additional counties—Ionia, Isabella, and Ottawa—bringing the total number of affected herds to four. On March 29, MDARD announced the state’s first HPAI-positive dairy herd located in Montcalm County. The U.S. Department of Agriculture’s (USDA) National Veterinary Services Laboratory confirmed these detections late in the evening on April 11.

"What is happening with HPAI in Michigan, mirrors what is happening in states across the country. This virus does not stop at county or state lines, which is why we must all be on high alert. This news is unfortunate and upsetting for our poultry and dairy farming families and communities," said Boring. "Experts from across the nation continue to assess this situation and provide insights into the role of HPAI in the affected livestock as they become aware. MDARD continues working with our federal, state, and local partners to respond robustly to this disease. Thanks to recent budget investments, MDARD is well poised to properly engage in this response. If you believe your livestock are showing clinical signs, contact your veterinarian immediately. We're all on the same team as we combat HPAI."

According to the USDA, the Food and Drug Administration, and Centers for Disease and Prevention, the commercial milk supply remains safe due to federal animal health requirements and pasteurization. Federal experts continue to stress there is no concern about the safety of the commercial milk supply or that this circumstance poses any increased risk to consumer health. Analysis of the virus from this case and the other cases of affected cattle has not shown any significant new adaptation to make the virus more transmissible between mammals. Therefore, the public health risk associated with HPAI remains low.

In Michigan, state law requires pasteurization for any milk sold in stores. Pasteurization has continually proven to inactivate bacteria and viruses, like influenza, in milk.

“HPAI doesn’t affect dairy cows the same way as it does with poultry. With proper veterinary care, cows are recovering. Biosecurity is the best line of defense. Still, we want to stress working with your veterinarian is fundamental for the recovery of affected dairy cows,” said State Veterinarian Dr. Nora Wineland, DVM, MS, DACVPM. “It continues to be vitally important for producers to work with their veterinarian, minimize the number of visitors to their farms, prevent contact between their animals and wildlife, and continue to monitor the health of animals vigilantly.”

Dairies continue to be strongly encouraged to implement enhanced biosecurity measures to help prevent the spread of disease. It is recommended to limit persons coming onto dairies to employees and essential personnel only and to follow best management practices, including washing hands often. Additional biosecurity resources are available through Secure Milk Supply.

HPAI is a highly contagious virus in birds and poultry that can be spread directly by infected wild birds or animals or indirectly through any item that has been exposed to the virus, such as equipment, feed, or the clothing and shoes of caretakers. The virus has been detected in various species of mammals, presumably after the animals come into contact with infected birds. The affected premises voluntarily stopped movement to limit the spread of the disease.

Producers who have concerns about their animals' health and/or questions regarding how to improve the measures they take to protect animal health on their farm should contact their veterinarian.

If anyone suspects the presence of HPAI or any other reportable animal disease in their domestic animals, contact MDARD immediately at 800-292-3939 (daytime) or 517-373-0440 (after-hours).

For more information on the detections of HPAI in cattle, please visit the U.S. Department of Agriculture’s website.

Detection of Highly Pathogenic Avian Influenza (H5N1) in
Dairy Herds: Frequently Asked Questions

Updated April 16, 2024
...

What is the appropriate nomenclature for this virus,
now that it has appeared in dairy cows?

From USDA’s perspective, highly pathogenic avian
influenza or H5N1 are the most scientifically accurate
terms to describe this virus. This is also consistent with
what the scientific community has continued to call the
virus after it has affected other mammals. As a
reminder, genomic sequencing of viruses isolated from
cattle indicates there is no change to this virus that
would make it more transmissible to or between
humans, and the CDC considers risk to the public to be
low at this time. However, people with more exposure
to infected animals do have a greater risk of infection.
Since the virus is not highly pathogenic in mammals,
H5N1 is the most fitting of the two scientifically correct
options. It is important to note that “highly pathogenic”
refers to severe impact in birds, not necessarily in
humans or cattle.
