Dairy Biosecurity
When a virus moves into a new geographical range or is reintroduced into a country that has maintained a negative status for a long period, SHIC’s Megan Niederwerder says it’s critical to reassess the risk to the U.S.
California Governor Gavin Newsom has declared a State of Emergency to address bird flu in California dairy cattle, ramping up monitoring, quarantine efforts, and resource deployment.
Shared employment, housing and movement of employees between facilities are possible factors. Such insights could potentially be leveraged to address biosecurity needs in the state and others as well, the agency says.
June 6 (Reuters) - The ongoing U.S. outbreak of avian flu in dairy cattle reached Minnesota on Thursday as the state announced its first infected herd.
Federal officials are seeking to verify the safety of milk and meat after confirming the H5N1 virus in nine states since late March. The public health risk is low, but is higher for those exposed to infected animals.
The agency will provide reimbursement for testing at an approved National Animal Health Laboratory Network laboratory.
The livestock industry needs a comprehensive, cohesive plan to address the virus. Producers, their employees and veterinarians need clear answers and support from U.S. agricultural leadership, moving forward.
USDA is now ordering all dairy cattle must be tested prior to interstate travel as a way to help stop the spread of HPAI H5N1. This comes a day after FDA confirmed virus genetic material was found in retail milk samples.
USDA said this week cow-to-cow transmission is a factor in the spread of avian flu in dairy herds, but it still does not know exactly how the virus is being moved around.
South Dakota Dairy Producers encourages all dairy producers to closely monitor their herd and contact their herd veterinarian immediately if cattle appear symptomatic.
Kay Russo, DVM, Novonesis technical services manager for dairy and poultry, emphasized the situation is rapidly evolving and more clarity will come with time as researchers learn more.
Ohio has become the sixth state where dairy cattle have tested positive for highly pathogenic avian influenza (HPAI), also known as bird flu.
Livestock producers and veterinarians are urged to practice good biosecurity practices to prevent transmission of the disease. Five states have also issued restrictions on dairy cattle movement.
USDA says genetic sequencing revealed the mystery illness impacting Texas dairies is the same strain of Highly Pathogenic Avian Influenza (HPAI) that’s been in the U.S. The virus is carried by wild waterfowl.
If you want to disrupt a government, disrupt the food supply. “Ag is critical infrastructure,” says Andrew Rose, strategic advisor. “Three weeks without food and agriculture, and it’s over.”
There is a big ‘ick’ factor with this tick. Hundreds can be found on a person after a 30- to 60-second ATV ride through an infested field, says one researcher. While any animal can provide a meal, they prefer cattle.
