Dairy herds in eight US states have been infected with H5N1, a type of influenza that can cause bird flu, with viral material detected in one fifth of milk samples.
While the virus is not easily caught by human beings, it has proved fatal in more than half of all human infections, so the recent findings have led to concern.
But should people be worried about catching the virus from tainted produce?
Outbreak in the US dairy industry
Herds of cattle in eight states have been infected with H5N1, with the animals possibly being exposed to the virus through infected milking equipment, by people moving between farms or by the transport of cattle.
Infected cattle often lose their appetite and suffer from mastitis, an inflammation of the udder, with up to one fifth of animals in herds becoming ill.
According to Prof Paul Digard, professor of virology at the University of Edinburgh in the UK, spread of H5N1 within the US dairy sector seems, until recently, to have largely gone unreported.
“It’s been happening without people identifying [it],” he said. " … Quite a few herds have been affected and there’s a wide geographical range, multiple sites … I’ve been told there’s probably cow-to-cow transmission.”
H5N1 is a subtype of Influenza A which, until now, has not infected cows, making recent events “something new and different, which is worrying”, according to Prof Digard.
“There’s no doubt the virus will be adapting to work better in cows, [which are] another mammal. In some respects, it’s going to make it better adapted to humans,” he added.
The US Department of Agriculture has issued requirements for the testing of some cattle if they are to be moved between states.
The milk of infected animals should be disposed of, but pasteurisation in any case inactivates virus particles and is thought to eliminate the risk of humans becoming infected from milk.
As milk sold in shops in the US should have been pasteurised, the US Food and Drug Administration has said that it is safe to drink. The organisation has, however, advised people not to drink raw milk.
What is bird flu?
Avian flu was recognised as far back as the late 19th century, but H5N1, which is strongly infective, was identified for the first time in 1996 in a goose on a farm in southern China. The following year, the first human cases emerged, in Hong Kong.
Bird flu spreads easily between farmed birds, more than half a billion of which have been slaughtered to control outbreaks.
Wild birds, too, become infected and, about four years ago, a strain appeared that was able to persist in such populations. Migratory birds have spread the disease globally.
Many wild bird populations have been devastated and the virus has killed large numbers of wild mammals too, including, for example, elephant seals, with the University of California, Davis reporting up to 96 per cent mortality among pups late last year.
“Although reported deaths among wild birds are in the tens of thousands, the actual numbers are thought to be in the millions,” Compassion in World Farming, a campaigning organisation, said in a 2023 report, Bird Flu: Only Major Reforms Can End It.
What are the threats to people?
A dairy industry employee in Texas is thought to be the only person to have been infected from the outbreaks in dairy cattle. This individual developed conjunctivitis, an eye inflammation, but did not become seriously ill.
The major concern the potential of the virus to mutate to a form that spreads easily between people, as this could result in many infections.
Until now, the US Centres for Disease Control and Prevention says that there have been no known cases of person-to-person spread of H5N1 viruses, adding that the situation “remains primarily an animal health issue”.
Prof Ian Jones, a professor virology at the University of Reading in the UK, has looked at genetic sequence data for the virus and said that this “doesn’t indicate there’s been any changes which would suggest it can transmit mammal-to-mammal”.
“Even though it’s the latest of these … viruses to get into a mammalian species, there doesn’t seem to be evidence of it adapting to that mammal. It would need to adapt if it was to get into people,” he said.
“It’s pretty clear it needs to change in several places in order to become a human transmissible virus … All the data I’ve seen doesn’t pick up the changes thought to be necessary.”
It is possible, Prof Jones said, that H5N1 is so specialised for infecting birds that it could be unable to evolve into a form that could easily infect people.
He noted that the number of cases in the birds in the UK recently has been lower than in previous years, but said this was not evidence that the virus was tailing off in bird populations.
Prof Digard said that while there was no immediate threat of a pandemic, the situation was serious enough that “people whose job it is to worry about it have to take it very seriously indeed”.
He said the UK, the US and other countries have “seed vaccines” that would be effective against bird flu, but it would take time to build up stocks if large numbers of people had to be immunised.
“You can do the forward planning and make sure as much is in place as possible in case you need to do it,” he said.
Is intensive farming a factor in the spread of bird flu?
Some researchers and campaign organisations have highlighted intensive farming as a factor that promotes the spread of disease between animals and so increases the risk of outbreaks.
Since H5N1 was identified, the global poultry population is thought to have doubled to about 30 million, which increases the risk of outbreaks.
“The sanitation is often very bad and large numbers are crowded together in high stocking densities,” said Prof Andrew Knight, a veterinary surgeon and professor of animal welfare at Griffith University in Australia.
He said that the conditions were “chronically stressful” for the animals, and this compromises their immune systems and makes it easier for pathogens to spread.
“It’s the perfect set up for the transmission of disease,” said Prof Knight, who last year, with Jenny Mace of the University of Winchester in the UK, co-wrote a study on influenza risks on mixed intensive pig and poultry farms.
He said mixed farms where animals were kept in intensive conditions were a high risk, as influenza could spread between wild birds, farmed birds and pigs, potentially leading to different forms of influenza coming into contact with one other, which could result in new pathogenic types emerging.

Tearful appearance
Chancellor Rachel Reeves set markets on edge as she appeared visibly distraught in parliament on Wednesday.
Legislative setbacks for the government have blown a new hole in the budgetary calculations at a time when the deficit is stubbornly large and the economy is struggling to grow.
She appeared with Keir Starmer on Thursday and the pair embraced, but he had failed to give her his backing as she cried a day earlier.
A spokesman said her upset demeanour was due to a personal matter.
Hydrogen: Market potential
Hydrogen has an estimated $11 trillion market potential, according to Bank of America Securities and is expected to generate $2.5tn in direct revenues and $11tn of indirect infrastructure by 2050 as its production increases six-fold.
"We believe we are reaching the point of harnessing the element that comprises 90 per cent of the universe, effectively and economically,” the bank said in a recent report.
Falling costs of renewable energy and electrolysers used in green hydrogen production is one of the main catalysts for the increasingly bullish sentiment over the element.
The cost of electrolysers used in green hydrogen production has halved over the last five years and will fall to 60 to 90 per cent by the end of the decade, acceding to Haim Israel, equity strategist at Merrill Lynch. A global focus on decarbonisation and sustainability is also a big driver in its development.

Who has been sanctioned?
Daniella Weiss and Nachala
Described as 'the grandmother of the settler movement', she has encouraged the expansion of settlements for decades. The 79 year old leads radical settler movement Nachala, whose aim is for Israel to annex Gaza and the occupied West Bank, where it helps settlers built outposts.
Harel Libi & Libi Construction and Infrastructure
Libi has been involved in threatening and perpetuating acts of aggression and violence against Palestinians. His firm has provided logistical and financial support for the establishment of illegal outposts.
Zohar Sabah
Runs a settler outpost named Zohar’s Farm and has previously faced charges of violence against Palestinians. He was indicted by Israel’s State Attorney’s Office in September for allegedly participating in a violent attack against Palestinians and activists in the West Bank village of Muarrajat.
Coco’s Farm and Neria’s Farm
These are illegal outposts in the West Bank, which are at the vanguard of the settler movement. According to the UK, they are associated with people who have been involved in enabling, inciting, promoting or providing support for activities that amount to “serious abuse”.

Sinopharm vaccine explained
The Sinopharm vaccine was created using techniques that have been around for decades.
“This is an inactivated vaccine. Simply what it means is that the virus is taken, cultured and inactivated," said Dr Nawal Al Kaabi, chair of the UAE's National Covid-19 Clinical Management Committee.
"What is left is a skeleton of the virus so it looks like a virus, but it is not live."
This is then injected into the body.
"The body will recognise it and form antibodies but because it is inactive, we will need more than one dose. The body will not develop immunity with one dose," she said.
"You have to be exposed more than one time to what we call the antigen."
The vaccine should offer protection for at least months, but no one knows how long beyond that.
Dr Al Kaabi said early vaccine volunteers in China were given shots last spring and still have antibodies today.
“Since it is inactivated, it will not last forever," she said.

Recyclables such as plastic, paper, glass will be collected from bins on the expo site and taken to the new expo Central Waste Facility on site
Organic waste will be processed at the new onsite Central Waste Facility, treated and converted into compost to be re-used to green the expo area
Of 173 tonnes of waste daily, an estimated 39 per cent will be recyclables, 48 per cent organic waste and 13 per cent general waste.
About 147 tonnes will be recycled and converted to new products at another existing facility in Ras Al Khor
Recycling at Ras Al Khor unit:
Plastic items to be converted to plastic bags and recycled
Paper pulp moulded products such as cup carriers, egg trays, seed pots, and food packaging trays
Glass waste into bowls, lights, candle holders, serving trays and coasters
Aim is for 85 per cent of waste from the site to be diverted from landfill

Three ways to boost your credit score
Marwan Lutfi says the core fundamentals that drive better payment behaviour and can improve your credit score are:
1. Make sure you make your payments on time;
2. Limit the number of products you borrow on: the more loans and credit cards you have, the more it will affect your credit score;
3. Don't max out all your debts: how much you maximise those credit facilities will have an impact. If you have five credit cards and utilise 90 per cent of that credit, it will negatively affect your score.
