H5N1 Cows

RFK Jr. supporters are hoping to see him legalize the consumption of raw milk. But with bird flu on the rise, experts warn it's not worth the risk.

Avian Influenza virus H5N1 2.3.4.4.b has recently been detected in cattle, with milk from infected animals reported to contain a high viral load, serving as a potential source for shedding and dissemination of this virus. Currently, pasteurization is the only widely recognized method for on-farm ina …

Pasteurization at 63°C and 72°C effectively inactivates influenza A viruses in milk, ensuring its safety for human consumption while viral RNA may still be detected.

Why the US dairy sector needs to act to stamp out H5N1 bird flu

Why the results surprised anyone is itself a surprise. After the state of California began testing dairy herds for highly pathogenic avian influenza, known also as bird flu or H5N1, in August, it found the pathogen on 645 dairy farms.

No. 5 on DTN's list of the Top 10 Ag Stories of the Year focuses on how dairy cattle have been affected by the H5N1 strain of avian influenza. Unlike the depopulations of poultry with a detection of highly pathogenic avian influenza at a facility, a dairy cow testing positive for H5N1 leads to a decrease in milk production and flu-like symptoms, which most recover from over time.

Bird flu infections among dairy cows and the humans exposed to them are rising. This is what scientists are watching for

Any existing herd health problems are amplified by HPAI H5N1, practitioners report. Across the U.S., they are asking regulatory agencies for more consistent testing and reporting protocols. They are also encouraging producers to invest dollars in better nutrition and cow comfort resources.

Clade 2.3.4.4b H5N1 is causing an unprecedented outbreak in dairy cows in the United States. To understand if recent H5N1 viruses are changing their receptor use, we screened recombinant hemagglutinin (HA) from historical and recent 2.3.4.4b H5N1 viruses for binding to distinct glycans bearing termi …

The FDA announced Monday it has begun collecting samples of aged raw cow's milk cheese to test for bird flu as the U.S. battles an outbreak of the virus.
