On Feb. 7, New York Governor Kathy Hochul issued an order to briefly shut dwell chook markets after circumstances of avian influenza, or chook flu, had been detected in seven markets in Queens, Brooklyn, and the Bronx up to now week. The closures apply to all chook markets, together with people who did not report any circumstances, in New York Metropolis, Westchester, Suffolk, and Nassau counties.
The order requires market house owners to promote or in any other case take away all dwell birds and conduct an intensive cleansing and disinfection of their amenities—even when chook flu wasn’t detected there. All markets should stay closed for 5 days after the cleansing to substantiate they’re freed from the H5N1 chook flu virus in order that the virus will not unfold once more when dwell animals are reintroduced.
Here is what to know in regards to the choice and what it means for chook flu to be detected in poultry.
Will closing the markets cut back the specter of chook flu?
“Getting forward of any organic risk—on this case, amongst birds—is nice to do,” says Dr. Raj Panjabi, senior accomplice at Flagship Pioneering and former chief of the Nationwide Safety Council’s pandemic workplace. Panjabi coordinated the White Home’s response to chook 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 degree, to coordinate.”
Jarra Jagne, professor of observe 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 group performs testing for the state for various infectious ailments 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 constructive checks 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. “Whenever you get a outcome from surveillance, now you’ve new data,” he says. “That is when it’s essential to take the prudent subsequent step, and that is the prudent subsequent step. We all know if we act now, we have now a greater probability of not seeing the virus unfold to others.”
How are birds in dwell markets getting contaminated?
There are a lot of 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 setting, birds on farms or business operations might turn out to be 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 additionally be spreading the virus to the chickens. “Folks strolling into markets might have been on the seaside and picked up some feces on their footwear from Canada geese,” says Jagne. “Farmers is also bringing it in from farms after strolling into hen homes with contaminated feces. It is actually laborious to pinpoint the supply of the virus.”
Ought to different states additionally shut down dwell chook markets?
“I believe it’s value contemplating,” says Panjabi. Throughout his tenure within the White Home, when H5 chook flu viruses started inflicting outbreaks, he says “it was actually difficult, as a result of in wild chook populations, there are specific occasions of yr when they are going to be extra energetic in migration and now have extra energetic virus. Detection of the virus in wild birds will get outbreaks spiraling.”

Panjabi says New York’s actions will likely be carefully watched by public well being and agriculture consultants. “What we’ve usually seen is that whereas there may be short-term ache, there may be much less unfold over the long run,” he says. Whereas business poultry farms have various insurance policies in place now to acknowledge and intervene if animals get sick, dwell chook markets are much less regulated and have fewer safety measures in place. Usually, “a vendor of birds could not acknowledge the signs and indicators of an infection, nobody is sporting private protecting gear, and they aren’t cleansing and sanitizing,” he says. “We all know the chance [of disease in people] will increase if there may be extra human interplay with poultry, particularly in less-controlled environments.”
How widespread is chook flu?
Outbreaks amongst business poultry farms have jumped within the final two months. The U.S. Division of Agriculture reveals that 85 flocks and almost 24 million birds had been affected by H5N1 by the top 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 consequence of larger quantities of H5N1 within the setting. Contaminated wild birds go away behind feces, which is available in contact with business flocks. “This virus is frequent within the setting, and it’s blowing round. That’s completely different from something we’ve seen earlier than,” he says.
Can I get chook flu from consuming hen or eggs?
In line with the U.S. Facilities for Illness Management and Prevention, consuming correctly cooked hen 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 chook flu (H5N1) stays low,” stated New York Metropolis well being division appearing 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 have now not seen.”
To guard themselves from the virus, McDonald says folks shouldn’t drink uncooked milk; pasteurization can kill the virus. And with regards to chickens, he says that “no birds from impacted institutions are offered or allowed to enter the meals provide.” But when an contaminated hen slips in undetected, cooking hen and eggs correctly can neutralize the virus and make the merchandise fit for human consumption.
