The closures apply to all chook markets, together with those who did not report any instances, 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 services—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 stay animals are reintroduced.
This is what to know in regards to the determination 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 associate 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 stage, to coordinate.”
Jarra Jagne, professor of observe within the division of public and ecosystem well being at Cornell Veterinary College, says a few of 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 plenty of infectious illnesses in chickens and different species. Due to the in depth testing community, she says, the instances “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 those who had not reported any infections. “If you get a end result from surveillance, now you’ve got new data,” he says. “That is when you have to take the prudent subsequent step, and that is the prudent subsequent step. We all know if we act now, we’ve a greater probability 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 setting, birds on farms or business operations might turn into uncovered and contaminated. Jagne says that in January, her lab discovered 23 instances of H5N1 in wild birds from 12 counties in New York. In markets particularly, individuals may additionally be spreading the virus to the chickens. “Individuals strolling into markets might have been on the seashore and picked up some feces on their sneakers from Canada geese,” says Jagne. “Farmers may be bringing it in from farms after strolling into rooster homes with contaminated feces. It is actually onerous to pinpoint the supply of the virus.”
Ought to different states additionally shut down stay chook markets?
“I believe it’s price 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 instances of yr 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 shall be intently watched by public well being and agriculture specialists. “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 plenty of insurance policies in place now to acknowledge and intervene if animals get sick, stay chook markets are much less regulated and have fewer safety measures in place. Sometimes, “a vendor of birds could not acknowledge the signs and indicators of an infection, nobody is sporting private protecting tools, and they aren’t 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 chook flu?
Outbreaks amongst business poultry farms have jumped within the final two months. The U.S. Division of Agriculture exhibits that 85 flocks and almost 24 million birds had been affected by H5N1 by the top of January.
Michael Osterholm, director of the Middle for Infectious Illness Analysis and Coverage on the College of Minnesota, says the growing variety of outbreaks could also be because of greater 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 totally different from something we’ve seen earlier than,” he says.
Can I get chook flu from consuming rooster or eggs?
In keeping with the U.S. Facilities for Illness Management and Prevention, consuming correctly cooked rooster and eggs is secure, however “consuming undercooked or raw poultry, eggs or consuming unpasteurized milk from contaminated dairy cows may be an publicity danger for an infection with avian influenza A viruses.”
“The present danger to New Yorkers of chook flu (H5N1) stays low,” stated New York Metropolis well being division performing commissioner Michelle Morse in a assertion. “Avian influenza viruses solely current a wider danger if the virus develops the power to transmit between individuals—which we’ve not seen.”
To guard themselves from the virus, McDonald says individuals mustn’t drink uncooked milk; pasteurization can kill the virus. And in terms of chickens, he says that “no birds from impacted institutions are bought 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 suitable for eating.
