Recent studies have shown that pasteurization may not completely eliminate the H5N1 bird flu virus from milk, with infectious virus remaining detectable even after treatment. Researchers found that high titers of the virus could survive pasteurization, raising concerns about potential transmission from dairy to poultry farms. The U.S. Department of Agriculture reported multiple new cases of H5N1 infections in dairy herds across several states, emphasizing the need for continued vigilance and research to prevent the spread of the virus.
In Opinion “How worried you should be about H5N1, the bird flu virus spreading on dairy farms in the United States, depends on whom you are,” writes the epidemiologist Jennifer Nuzzo. Here’s how to think about the risk. https://t.co/Ii4zz9RvXR
Idaho has overtaken Michigan as the state with the most #H5N1 #birdflu detections in dairy herds. @USDA announced 7 new herds today: Idaho (3), Texas (2) & Iowa (2). It still hasn't added 2 Iowa herds & 3 from Minnesota. Cumulative national total: 114. https://t.co/6E4b6hAXBu https://t.co/JMIVPBjRQG
H5N1 bird flu found at 5 more dairy farms, including 3 in Idaho and 2 in Texas https://t.co/dN95VkbORq
Canada's food regulatory agency has tested 600 samples of commercially purchased milk from across the country. It has found no evidence of #H5N1 #birdflu in the Canadian milk supply. That's double the number @FDA has disclosed testing in the US. https://t.co/c4sZMlMOn2
Bird flu has been detected in 92 dairy cattle herds across 12 states, according to the Centers for Disease Control and Prevention.

Since an outbreak of bird flu spread to dairy cows in late March, at least 21 cats in nine states also have caught the virus. Here's how to keep pets safe. (via @nytimes) https://t.co/rJn6iAkP7b
#H5N1 #birdflu update: Minnesota has announced 3 new herds and Iowa added another today (in addition to the one it reported on Saturday). I'll wait a bit to see if @USDA is going to update its list today.
A small but detectable amount of H5N1 bird flu survived a standard pasteurization method on milk infected with high concentrations of the virus, National Institutes of Health scientists wrote Friday in the New England Journal of Medicine. https://t.co/fWqL9oFe4w
The bird flu outbreak in dairy cattle has so far infected three farmworkers in the U.S., as far as public health authorities know. All of them have had mostly mild symptoms. But that doesn't mean that the virus will remain benign. Here is what to know. https://t.co/Xzh8HrB2ML
Looks like a H5N1 Dairy Herd (4th) in Kandiyohi County as Dairy Herds proximity to H5N1 poultry in Minnesota becomes more obvious ( see attached map with poultry and Dairy recently H5N1 confirmed farms) Dairy confirmations in tan colored counties https://t.co/JFIJ8GLv6V
Seth Berkley voiced criticism last week over the U.S. response to the H5N1 bird flu outbreak in dairy cows. Read the first in a series of bird flu updates that STAT will be publishing every Monday. https://t.co/iFNXnoKwsU
"The number of dairy herds w/documented #birdflu infections has risen rapidly in recent weeks. Federal officials’ reliance on individual farmers to track the spread is leaving the industry vulnerable." And all of us as well. Good piece @politico https://t.co/8drp6jptMb #H5N1 https://t.co/csA5jSIzVs
A bird flu outbreak in the U.S. has infected more than 90 herds of dairy cows in 12 states. Along the way, the virus has also caused mounting casualties in cats. Here is what you can do to keep your pets safe from the H5N1 virus, according to experts. https://t.co/p1v4dSKZF2
Missed this over the weekend: Iowa announced it has detected a 6th #H5N1 #birdflu infected dairy cow herd. This would bring the national total to 105 in 12 states. https://t.co/lm6qmb7HRj https://t.co/c13TqRwKTQ

#H5N1 @CDCgov @USDA [Iowa] Secretary Naig provides H5N1/HPAI update "..one thing that is different this year is that the strain showing up in bird populations shows the markers of having already been in dairy cattle" https://t.co/dbRMPNS6rP
Pasteurization may not clear #birdflu virus from heavily infected milk. In raw milk samples spiked with high amounts of bird flu virus, small amounts of infectious virus were still detectable after treatment with a standard pasteurization method. https://t.co/WkofAxQtR0
"It’s important to continue learning more about what happens to the #birdflu virus as it moves from an infected dairy cow and into the milk supply. Even with very efficient inactivation from pasteurization, H5N1 #birdflu should not be in our milk." https://t.co/uPv4vqHOn8
.@USDA reported 5 new #H5N1 #birdflu affected dairy herds in Colorado today & reported Iowa's 3rd, which Iowa reported 6/12. But Iowa reported #4 & #5 today, bringing the national total to 104 herds in 12 states — to the best of my knowledge. https://t.co/6E4b6hAXBu https://t.co/lzskSPbFIJ
“The good news is that at the lower temperature, heat inactivated the virus in raw milk within two minutes—which means that commercial pasteurization, which generally heats milk to 63°C for 30 minutes, should be sufficient to inactivate H5N1.” https://t.co/aTFBP6Upm2
"This finding indicates the potential for a relatively small but detectable quantity of H5N1 virus to remain infectious in milk after 15 seconds at 72℃ if the initial virus levels were sufficiently high” https://t.co/Bzu0Xo07I6

So how exactly are workers spreading H5N1 from dairy to poultry farms? @USDA's Kammy Johnson said: - genetic sequences show relationships between viruses on dairy to poultry farms - previous outbreaks show they can carry virus on clothing and boots https://t.co/a7GXFED3Ez https://t.co/silKtrkTvI https://t.co/ul7Oz51VnL
In lab setting, researchers report a small but detectable quantity of #H5N1 #BirdFlu virus remained infectious in milk after heating for 15 secs at 72°C (pasteurizing). Of concern given other reports of very high titers present in some milk. #MedTwitter https://t.co/CD6ezafKQp
Pasteurization does not necessarily kill #H5N1 from milk samples. I have been saying that for months now. No idea why people assumed that with a completely new virus. Data published today at @NEJM https://t.co/b6uzbvNF83 https://t.co/kAESfibXcU
