Mandy Melnyk has made some modifications to her egg and poultry business in the previous few months. The proprietor of Meadow Creek Farms in northern Alberta serves about 200 households a month along with her egg subscriptions and broiler chickens—however now, as an alternative of shoppers coming to choose up their orders from Melnyk immediately, she’s spending numerous time within the automotive, delivering them herself.
Like many poultry farmers, Melnyk is anxious about Highly Pathogenic Avian Influenza (HPAI), or hen flu. The virus has been plaguing the industry for the reason that Nineteen Sixties, however the present H5N1 variant first got here to prominence within the mid-Nineteen Nineties, when there have been giant outbreaks in southern China and Hong Kong. This present wave, which began final yr, has unfold to greater than 80 countries. While there are ebbs and flows of illness transmission, the large outbreak that plagued producers in 2022 hasn’t proven indicators of slowing but.
Anybody who comes into your yard is a danger, she says. “[The disease is] so small, it’s like a minute little piece of dust. So, you’re at risk all the time. Anything you do with poultry is truly just a risky kind of business,” says Melnyk. “You have to get really creative, and you have to be on the ball. For me, going directly to people’s houses is the safest way I can keep all sorts of things off my farm.”
Rather than let prospects come to her, and probably infect the birds on her property, Melnyk goes to them, after which disinfecting when she will get again home. It’s a part of a stringent biosecurity regime, which will get up to date and tweaked as wanted. “I have a zillion pairs of different rubber boots. I have rubber boots all over my yard, to use for different areas. My boot management is very good,” says Melnyk. She additionally makes use of vinegar and disinfectant as she strikes between buildings, and he or she’s holding her birds inside extra, to make sure they steer clear of wild fowl.
Most of these wild birds, together with Canada geese, ought to have left northern Alberta by means of September and October. But when Modern Farmer reached Melnyk in mid-November, the geese have been nonetheless there. “This warm spell that we’re having is incredibly frightening, because it slowed down the migration of the geese,” says Melnyk. “We have grass turning green. Dandelions are coming up. I saw birds around that should have been gone four weeks ago.” With the wild birds sticking round, Melnyk is anxious and harassed, discovering methods to get her vitality out.
“I actually have to run for a few miles every second day in order to function, just because I’m constantly afraid.”

The nervousness is comprehensible. There are at present 69 million birds affected with HPAI, in over 47 states, with infections placing industrial barns and yard flocks alike. The greatest hit to date has been in Iowa, the place a industrial egg-laying operation misplaced 1.6 million birds in late November. While that’s excessive, representatives from the USDA’s Animal and Plant Health Inspection Service (APHIS) say that we really noticed much more infections final yr. “The overall number of birds affected was significantly higher in 2022 than it has been so far in 2023. In fact, we’ve seen 100 cases in commercial poultry facilities so far in 2023, versus 306 in commercial facilities in 2022—a decrease of more than 80 percent to the number of birds affected by the virus in 2023.”
But, surprisingly, these aren’t distinct an infection cycles of HPAI. This present wave of hen flu is definitely the identical wave we have been preventing final yr; there hasn’t been a full cease when the USDA can declare the outbreak over.
“It’s kind of convenient for us, as morbid as that sounds, because we just keep the response going. We didn’t shut our office down or close the books, and then have to restart everything,” says Michael Cruson, communications director for the Minnesota Board of Animal Health. Minnesota, the turkey capital of the nation, has seen greater than 600,000 birds hit with HPAI prior to now 4 months.
The final distinct wave of HPAI was in 2014 by means of to 2015, although APHIS say it’s troublesome to check the 2 outbreaks. “More than 70 percent of cases during the 2014/2015 outbreak were due to farm-to-farm spread, versus fewer than 20 percent of the cases in this outbreak. The cases in the current outbreak are primarily being introduced directly from wild birds that are carrying the virus to domestic birds,” say representatives from APHIS in an electronic mail to Modern Farmer. As contaminated birds migrate, consuming from shared water sources or leaving stool or urine in shared areas, industrial birds get contaminated. It is sensible that there could be an upswing within the final month or so, as these birds lastly begin making their approach south.
“Hopefully, this is all leading to a downswing, where we can catch a break from this virus,” says Cruson. “It’s just taking a really long time to get to zero, where it’s gone.”

Producers can check usually for the virus, however the course of can often be delayed. The first check in an space, says Cruson, is commonly achieved by the state laboratory after which confirmed by the USDA. That means there could be a wait of a day or two, the place the virus could also be current in an operation, however state companies aren’t capable of take motion with out federal approval. That’s a reasonably reactive mannequin, says Shaun Holt, who’s encouraging a transition to a extra preventative course of.
Holt is the CEO of Alveo Technologies, a testing and diagnostics firm that’s at present finalizing its preliminary testing of the be.well, a tool that enables farmers and producers to do preliminary testing on website. “We want to take the testing out of the lab, where it’s centralized, and you need PhD scientists to run the instruments,” says Holt. Its machine, barely smaller than a smartphone, is moveable and rugged, so farmers can slip it of their pocket and convey it with them on their every day rounds. There are eight totally different testing wells, the place producers can use any bodily fluid from the hen (nasal fluid, saliva, blood, urine or stool) to check for a number of viruses directly.
The machine permits geolocation, and farmers can enter information comparable to the precise coop quantity and flock to maintain observe of which viruses are exhibiting up the place and preserve a log for state or federal databases. In 2024, the corporate hopes to increase the testing section to extra industrial prospects. The objective, says Holt, is to decentralize that testing mannequin and permit farmers to see what’s occurring of their flocks sooner.

Until then, one of the best factor producers can do is be strict with bio-security, says Dustan Clark, poultry well being veterinarian for the University of Arkansas. He recommends “putting up the birds in a pen that’s roofed over, even if it’s as simple as a plastic tarp on top, to help prevent contamination from wild bird droppings. If you’ve got a pond on your premises, make sure your birds don’t go near that pond, and don’t go near the pond yourself.” Be certain to wash and disinfect footwear earlier than going right into a coop, however one of the best factor to do is keep away from areas comparable to parks, the place wild birds congregate, he says. Above all, take note of your birds. Look at how a lot feed they’re consuming, how a lot water they’re consuming, what number of eggs they’re laying. If issues look off, belief your intuition. “We call it ADR: Ain’t Doing Right,” says Clark. “And as a producer, you know when your birds just aren’t doing right.”
As we go into the winter season, it stands to cause that instances will drop as wild hen migration wraps up, and Clark is hopeful that’s the case. “Are we going to be dealing with it in the spring? We just don’t know at this time. Almost anybody’s guess.”
For Mandy Melnyk, spring migration is a good distance off, however the well being and security of her birds is at all times on her thoughts. While she’s heard of the HPAI vaccine, it may very well be some time earlier than that remedy is instantly available to her. Instead, she is making ready to cope with an elevated danger of hen flu going ahead. “I think that climate change, and the migratory patterns of our birds changing, is a problem that nobody will fix, unless everybody pays attention.”
