The closures apply to all hen markets, together with people who did not report any circumstances, in New York Metropolis, Westchester, Suffolk, and Nassau counties.
The order requires market homeowners to promote or in any other case take away all stay birds and conduct a radical cleansing and disinfection of their amenities—even when hen flu wasn’t detected there. All markets should stay closed for 5 days after the cleansing to verify they’re freed from the H5N1 hen flu virus in order that the virus will not unfold once more when stay animals are reintroduced.
Here is what to know concerning the resolution and what it means for hen flu to be detected in poultry.
Will closing the markets cut back the specter of hen flu?
“Getting forward of any organic menace—on this case, amongst birds—is sweet to do,” says Dr. Raj Panjabi, senior associate at Flagship Pioneering and former chief of the Nationwide Safety Council’s pandemic workplace. Panjabi coordinated the White Home’s response to hen flu in 2022. “I like that New York is being proactive right here, and leveraging the state agriculture commissioner and the well being commissioner on the state in addition to metropolis stage, to coordinate.”
Jarra Jagne, professor of follow within the division of public and ecosystem well being at Cornell Veterinary Faculty, says among the contaminated birds had died and had been reported by market operators, whereas some had been detected by the state’s routine surveillance for H5N1. Jagne’s lab is funded by New York State Animal Well being Diagnostics Lab, and her crew performs testing for the state for quite a lot of infectious illnesses in chickens and different species. Due to the intensive testing community, she says, the circumstances “had been picked up fairly early.”
New York State well being commissioner Dr. James McDonald says as soon as the optimistic exams had been confirmed, the state well being and agriculture departments determined to shut all markets in a number of counties, together with people who had not reported any infections. “If you get a outcome from surveillance, now you may have new data,” he says. “That is when you could take the prudent subsequent step, and that is the prudent subsequent step. We all know if we act now, we’ve a greater likelihood of not seeing the virus unfold to others.”
How are birds in stay markets getting contaminated?
There are numerous methods birds may very well be contaminated. Some might have picked up the an infection from the farms the place they originated; the virus is at present prevalent in wild birds, and as they go away feces within the surroundings, birds on farms or business operations might turn into uncovered and contaminated. Jagne says that in January, her lab discovered 23 circumstances of H5N1 in wild birds from 12 counties in New York. In markets particularly, folks may also be spreading the virus to the chickens. “Folks strolling into markets might have been on the seashore and picked up some feces on their sneakers from Canada geese,” says Jagne. “Farmers is also bringing it in from farms after strolling into rooster homes with contaminated feces. It is actually laborious to pinpoint the supply of the virus.”
Ought to different states additionally shut down stay hen markets?
“I feel it’s price contemplating,” says Panjabi. Throughout his tenure within the White Home, when H5 hen flu viruses started inflicting outbreaks, he says “it was actually difficult, as a result of in wild hen populations, there are specific instances of 12 months when they are going to be extra lively in migration and now have extra lively virus. Detection of the virus in wild birds will get outbreaks spiraling.”

Panjabi says New York’s actions can be carefully watched by public well being and agriculture consultants. “What we’ve usually seen is that whereas there’s short-term ache, there’s much less unfold over the long run,” he says. Whereas business poultry farms have quite a lot of insurance policies in place now to acknowledge and intervene if animals get sick, stay hen markets are much less regulated and have fewer safety measures in place. Usually, “a vendor of birds might not acknowledge the signs and indicators of an infection, nobody is sporting private protecting gear, and they don’t seem to be cleansing and sanitizing,” he says. “We all know the danger [of disease in people] will increase if there’s extra human interplay with poultry, particularly in less-controlled environments.”
How widespread is hen flu?
Outbreaks amongst business poultry farms have jumped within the final two months. The U.S. Division of Agriculture reveals that 85 flocks and practically 24 million birds had been affected by H5N1 by the tip of January.
Michael Osterholm, director of the Heart for Infectious Illness Analysis and Coverage on the College of Minnesota, says the rising variety of outbreaks could also be as a result of greater quantities of H5N1 within the surroundings. Contaminated wild birds go away behind feces, which is available in contact with business flocks. “This virus is widespread within the surroundings, and it’s blowing round. That’s completely different from something we’ve seen earlier than,” he says.
Can I get hen flu from consuming rooster or eggs?
In response to the U.S. Facilities for Illness Management and Prevention, consuming correctly cooked rooster and eggs is protected, however “consuming undercooked or raw poultry, eggs or consuming unpasteurized milk from contaminated dairy cows is also an publicity threat for an infection with avian influenza A viruses.”
“The present threat to New Yorkers of hen flu (H5N1) stays low,” mentioned New York Metropolis well being division performing commissioner Michelle Morse in a assertion. “Avian influenza viruses solely current a wider threat if the virus develops the flexibility to transmit between folks—which we’ve not seen.”
To guard themselves from the virus, McDonald says folks shouldn’t drink uncooked milk; pasteurization can kill the virus. And relating to chickens, he says that “no birds from impacted institutions are offered or allowed to enter the meals provide.” But when an contaminated rooster slips in undetected, cooking rooster and eggs correctly can neutralize the virus and make the merchandise fit for human consumption.
