Nature: Huge amounts of bird-flu virus found in raw milk of infected cows

New findings point to the milking process as a possible route of avian-influenza spread between cows — and from cow to human.

Poem of the day... (human poem, mine!)

Make me a a bird flu milkshake please
Something I can drink with ease
Full of viral particles, raw and alive
So my immune system can go into overdrive

Hopefully it won't make me too sick
Or make my eyes bloodshot and snot too thick
Or cause a fever, or gastric distress
Or make me vomit all over my dress

Raw milk is healthier for you they say
Or so the cuckoo raw milk nuts yell today
Until they're all killed off and dead of the flu
or they survive, and they just pass it on to you

LA Times: Despite the spread of bird flu, lawmakers in some states are pushing to legalize raw milk https://www.latimes.com/environment/story/2024-06-04/as-bird-flu-pandemic-widens-state-lawmakers-push-to-legalize-raw-milk #h5n1 #hpai #birdflu #milk

@B_Whitewind Yeah, I think really the question on legalization is if you let people market/sell it in stores (where the unsuspecting/clueless might buy it, thinking it's "healthier", and it kills a bunch of kids). But, I get it -- I mean, don't stop the stupid if they really want to try to get themselves sick.

An increase in flu viruses detected at wastewater treatment plants in California in recent weeks has sparked concern that the #H5N1 bird flu may be spreading more rapidly than anticipated, potentially putting the state’s 1.7 million dairy cows at risk for infection.

USDA just updated its page with THIRTEEN new herds infected since their last update.

The new herd infections are in South Dakota, Michigan and Idaho, with Idaho logging the most at 8 new herds infected.

Several of the infections were confirmed by a NVSL on the 28th, which is last Tuesday, so the USDA is continuing its pattern of untimely updates while saying "Data updated weekday by 4 pm ET."

That makes 80 herds with confirmed infections in 9 states.

I am far more terrified about the pending virus that is spreading than at the latter’s worst.

👉🏾 U.S. to make millions of bird flu vaccine doses this summer, as cases grow https://www.cbsnews.com/news/bird-flu-vaccine-doses-this-summer-cases/

COVID’s fatality rate was between 1%-3% (which is usually high for a virus).

I have read reports about H5N1 having close to 60% fatality rate. I need to stock up on masks again.

@darnell @DrPen I’m in NZ. Less so an experience of abuse when out and about, as much as just being frozen out/ignored, and ultimately left behind by some folk when I got long COVID.

My friends/family back in the UK definitely don’t understand why I’m not giving the virus a free ride though

dave,
@dave@social.lightbeamapps.com avatar

@darnell @DrPen but really it’s less about active abuse from randoms, and more about that general level of it being normal for people not to bother mitigating it any more.

If you understand the science of it all, and still don’t mask etc, then that behaviour adds up the same as anti-maskers approach to it all really

Another dairy worker, this one in Michigan, has tested positive for H5N1 after showing signs of illness. Like the two others, this person had eye symptoms. Unlike the others, this person had a productive cough. If it is infecting human respiratory tissues, that isn't good, as coughing makes someone far more likely to spread the disease onward.

"Researchers at the University of Wisconsin-Madison squirted raw H5N1-containing milk from infected cows into the throats of anesthetized laboratory mice, finding that the virus caused systemic infections after the mice were observed swallowing the dose. The illnesses began quickly, with symptoms of lethargy & ruffled fur starting on day 1. On day 4, the animals were euthanized to prevent extended suffering. Subsequent analysis found that the mice had high levels of H5N1 bird flu virus in their respiratory tracts, as well their hearts, kidneys, spleens, livers, mammary glands, and brains.

"Collectively, our data indicate that #HPAI [Highly Pathogenic Avian Influenza] A(H5N1) virus in untreated milk can infect susceptible animals that consume it," the researchers concluded. The researchers also found that raw milk containing #H5N1 can remain infectious for weeks when stored at refrigerator temperatures."https://arstechnica.com/science/2024/05/after-mice-drink-raw-h5n1-milk-bird-flu-virus-riddles-their-organs/

The recent news from the United States of bird flu in dairy cows has alarmed the Cambodians.
“The lesson learned from the U.S. is that we need to look more in these other animals and do more tests,” said Dr. Tum Sothyra
The ministry is expanding testing to animals that are likely to eat infected birds,such as ferrets &wild dogs, but he hopes it can find the funds to test cows as well
Poultry, however, is more difficult to surveil.

“raw milk containing #H5N1 can remain infectious for weeks when stored at refrigerator temperatures”

Common sense substantiated by research, that.

Researchers also gave mice raw milk containing H5N1. The virus almost immediately began affecting them.

Euthanized on day four, and still:
“the mice had high levels of H5N1 bird flu virus in their respiratory tracts, as well their hearts, kidneys, spleens, livers, mammary glands, and brains.”

"New tests confirm milk from flu-infected cows can make other animals sick — and raise questions about flash pasteurization"

More research:

<💬>
First, they confirmed the raw milk was chock-full of H5N1 virus. Then, they stored some of the raw milk at refrigerator temperature to see if levels of the virus in milk would drop off over time. Over 5 weeks, viral levels in raw milk dropped a bit, but not much.
</💬>

This should also imply that the virus gets into fermented raw milk products. And if you look for "raw milk ice cream", you'll see that there are sellers and there is a market. I find the issue of ice cream more interesting because it can be stored for a long time, which means outbreaks later.

<💬>
Heating the milk to 72 degrees Celsius, or 181 degrees Fahrenheit, for 15 or 20 seconds — conditions that approximated flash pasteurization — greatly reduced levels of the virus in the milk, but it didn’t inactivate it completely.
</💬>

This is flash pasteurization, meaning that the heat is applied for a shorter duration, but at a higher temperature. And this is the most common method; I've seen it in action and it's usually some nice machine that efficiently does this, which means that it's cheaper than the "vat pasteurization". Speaking of vat, I'm not sure how many people still do this since the rise of "cartons", but I grew up with raw milk plastic bags and boiling the milk; unfortunately, I wasn't raised vegan. Anyway, I distinctly remember the challenges of boiling cow milk, so I wonder how many of the raw milk buyers are doing their own pasteurization (boiling = vat pasteurization at high temperature).

<💬>
“But, we emphasize that the conditions used in our laboratory study are not identical to the large-scale industrial treatment of raw milk,” senior study author Dr. Yoshihiro Kawaoka, a virologist who specializes in the study of flu and Ebola, said in an email.
</💬>

It's true that further processing, which is done in these milk factories, can change the results. They mention the importance of homogenization, but there's also dilution as cow milk is pooled from many sources, so if just a small % of that is infectious, then the dilution will reduce the viral load per unit of fluid, making pasteurization more likely to succeed. I'm not sure about the homogenization and emulsification help in this sense:

<💬>
a process that emulsifies the fat globules in milk so the cream won’t separate.
</💬>

I'm not sure about this one. I've seen this in research on tuberculosis bacteria in milk, but not for viruses. Just like with SARS-CoV-2, there is a question of the non-linear effects of viral load (more viral particles, exponentially worse outcomes). They can't really answer. And, who knows, maybe homogenization will make it easier to cow milk to be accidentally aerosolized and/or inhaled.

I wouldn't CNN to go for the pessimistic reporting...

So, yeah. The raw cow milk drinkers are working stochastically to bring about a new pandemic. And probably new waves of as a bonus tuberculosis. Did you know about drug resistant tuberculosis? https://en.wikipedia.org/wiki/Multidrug-resistant_tuberculosis

@dancingdogs Mice seem to much more susceptible to H5N1 strains adapted to birds than humans are. I am not suggesting raw milk is a good idea, because it objectively is not. For one thing, I don't really want to catch or spread tuberculosis, either.

Clarification from the USDA re: #H5N1

"...interstate movement for a lactating dairy cow from a sale barn directly to a slaughter facility requires only a Certificate of Veterinary Inspection (CVI) stating that the animal is clinically healthy; no testing is necessary."

I'll repeat that in case you missed it.

NO TESTING IS NECESSARY for dairy cows being sent to slaughter.

I suspect "clinically healthy" is a bit misleading in a similar way that "mild #Covid" is

@justyourluck Also: cows from dairy operations are mostly not slaughtered for human consumption. So this meat is going into stuff like dog food. Where it can encounter yet another mammal, if it somehow escapes thermal destruction.

@justyourluck@masto.ai avatar

@grumpybozo

As far as pet food goes, there has been ZERO warnings to consumers of raw pet food with regards to H5N1 so if that's where it's going, this needs to be addressed in a big way.

Y'all will find this... interesting.

I was helping a farmer friend today get her car up to her mechanic's place, which is about 10 miles out of town.

On the drive back, she took a call from someone who was looking for raw cow's milk.

She's only on Facebook as far as social media goes, so she hasn't seen any of the news stories about people seeking out raw milk in order to try to infect themselves with #H5N1 to "gain immunity" from it.

She was gobsmacked!

I was trying SO hard not to laugh while she took the call.

I told her that I've seen a number of news stories about people doing exactly this. I said what scares me the most is, the mortality rate is over 50%. One in two people! Why would anyone think this is an acceptable risk?

She appreciated the information I gave her and said that she would adjust her response when she received more calls.

Apparently she's received a lot of calls recently.

She's not even a dairy farmer!

I know 100+ years ago when we didn't have #vaccinations, #antibiotics, or #antivirals, exposing yourself to pathogens was one way to possibly gain immunity from whatever was going around.

But thousands upon thousands of people were sickened and died from things that we can now prevent or treat with drugs, #sanitation, #hygiene, #masks, and vaccines. It wasn't all bread and roses in pre-modern America. Our average life expectancy was almost half what if is today.

"Natural" is not inherently superior. Immunity debt is fucking bullshit. Exposing yourself willingly to a deadly pathogen does not increase your chances of living longer or being healthier afterwards. If someone did this to their kids? It would be flat out child abuse.

Yet, I always forget that most of the population doesn't read a book after they leave school, doesn't believe in science, and thinks if something is on the internet, it must be true.

Even and especially, people in my profession and allied professions believe the wackiest ideas about how the the human body works that are simply not true.

I'm pretty tired of the stupidity of other humans at this point. Go ahead. Drink the raw milk. Take yourself out of the gene pool. I know I can't do anything about it once you've made up your mind to do something so risky and stupid. SMH

We've currently got 2 confirmed dairy worker H5N1/HPAI infections in 2 months from 52 confirmed infected dairy herds. There were 27,932 dairy herds in the US as of 2002. Back of the napkin math tells me that if all those herds became infected, one would expect dairy workers to become infected at a rate of around 537 workers a month, but we're of course taking stringent measures to ensure more dairy herds don't get infected right? Right? Right?

Just to clarify a technicality from some of today’s headlines:
There was actually a <third> person diagnosed with highly pathogenic avian influenza #H5N1 today according to the CDC dashboard. It was the <second> among dairy workers (both of whom had conjunctivitis, whereas the case of an infected poultry worker presented with fatigue).

@haeji@mastodon.online avatar

So second human case of H5N1 was NOT detected with nasal swab, but EYE swab. Sounds like if you have pink eye, go get tested from the eye for potential #birdflu #H5N1. I have to ask, how many of the 40 human tests were done with eye swab?
"A nasal swab from the Michigan worker tested negative for influenza in the state, but an eye swab from the patient was shipped to CDC and tested positive for the H5N1 virus, the CDC said."
