“Even with biological, technological, and logistical hurdles surpassed, the decision around vaccination seems to be a monetary one. Beyond the cost of vaccination, there’s the potential of losing key trade partners. Trade agreements, especially for meat, are notoriously delicate, in part because of the risk of introducing infectious diseases and pests into a country’s food chain but more so because governments need to protect the agricultural industry from foreign competition. The National Chicken Council is opposed to vaccination efforts. The National Turkey Federation says unilateral vaccination “would have a severe impact on exports” but that it has urged — and continues to urge — the federal government to “move as rapidly as possible to try to develop new agreements” with trading partners.
“Meat is a highly politically sensitive issue for many countries, and the entire livestock industry is protected in many countries for various reasons,” said Aratchilage. Introducing bird flu vaccines is not going to be easy, he added. “It’s a political decision more than a scientific decision.””

“The egg industry, like much of the agricultural sector, is commanded by a few heavyweights — the biggest, Cal-Maine Foods, controls 20 percent of the market — that leave little slack in the system to absorb and isolate shocks like disease.
Hundreds of thousands of animals are packed tightly together on a single farm, as my colleague Marina Bolotnikova has explained, where disease can spread like wildfire. According to the government and corporate accountability group Food & Water Watch, three-quarters of the country’s hundreds of millions of egg-laying hens are crammed into just 347 factory farms.
The system also uses genetically similar animals that farms believe will maximize egg production — but that lack of genetic diversity means animal populations are less resistant to disease.
When a hen gets infected, stopping the spread is an ugly, cruel business; since 2022 it has led to the killing of 85 million poultry birds. For the consumer, it often means paying a lot more than usual for a carton of eggs.
Preventing any outbreaks of disease from ever happening isn’t realistic, but the model of modern industrial farming is making outbreaks more disruptive.
And it’s not just these disruptions driving price spikes. Egg producers also appear to be taking advantage of these moments and hiking prices beyond what they’d need to maintain their old profit margins.”
…
“Because our food system is so concentrated and intermingled, it also means any single supply chain hiccup — whether due to disease, wars, or any other reason — can have ripple effects on others, affecting prices in a vast number of essential consumer goods and services.”

Bird flu in milk is alarming — but not for the reason you think

“the rise of “ventilation shutdown plus” (VSD+), a method being used to mass kill poultry birds on factory farms by sealing off the airflow inside barns and pumping in extreme heat using industrial-scale heaters, so that the animals die of heatstroke over the course of hours. It is one of the worst forms of cruelty being inflicted on animals in the US food system — the equivalent of roasting animals to death — and it’s been used to kill tens of millions of poultry birds during the current avian flu outbreak.
As of this summer, the most recent period for which data is available, more than 49 million birds, or over 80 percent of the depopulated total, were killed in culls that used VSD+ either alone or in combination with other methods, according to an analysis of USDA data by Gwendolen Reyes-Illg, a veterinary adviser to the Animal Welfare Institute (AWI), an animal advocacy nonprofit. These mass killings, or “depopulations,” in the industry’s jargon, are paid for with public dollars through a USDA program that compensates livestock farmers for their losses.
In America’s peer countries, ventilation shutdown has been effectively banned because it’s so inhumane; last year, Danish bioethicist Peter Sandøe told me he was “shocked” by the method’s prevalence in the US and that in the European Union, relying on it would be illegal.
Thousands of US veterinarians, animal welfare experts, and animal advocates have protested the use of ventilation shutdown. But a growing body of evidence obtained through public records requests shows that the poultry industry, in partnership with agricultural and veterinary authorities, is quietly normalizing ventilation shutdown and planning its further use — even though the USDA’s own policy says it can only be used as a last resort.”

“A widespread avian flu outbreak devastated the poultry industry in 2022, causing the deaths of more than 43 million hens. December egg inventories were down nearly 30 percent from the year before, just in time for the holiday baking season. Under the basic rules of economics, a persistent drop in supply leading into a time of increased demand is bound to have this result.”
“The squeeze on eggs is so bad that some grocery stores are reporting shortages, and some are even limiting the number of cartons customers can purchase.
It’s a significant change for what’s long been a reliably cheap staple, and there’s one major culprit: the bird flu.”
…
“The last year has brought the worst bird flu outbreak in US history, and there are no signs it’s going to relent soon. Some 57.8 million birds in the US — mostly egg-laying hens — have died as a result of bird flu outbreaks surpassing the previous record of 50.5 million in 2015, and it’s not letting up. Just in the 10 days prior to Christmas, 1.5 million egg-laying hens died.
The virus is expected to continue to circulate among wild birds and the ones we raise for food for the duration of winter, meaning egg prices — along with prices for turkey — could remain high for the foreseeable future.”
…
“most victims don’t die from the virus itself. Rather, they’re culled, or proactively killed, in a brutal effort to prevent the virus from doing even more damage.”
…
“a major reason why bird flu is so destructive in the US is that factory farms — with so many chickens and turkeys in such close quarters — are the perfect playing field for the virus, which is why farmers are so quick to cull infected flocks. But that very fact raises a simple, but surprisingly controversial question: If avian flu is so deadly and so economically destructive, why on earth aren’t we vaccinating birds against the virus?”
…
“For countries in which poultry exports make up a big share of the industry’s revenue — such as the US and many European countries — vaccines have largely been a nonstarter, even though they have the potential to severely limit the death toll of mass culling. Why? Blame the “DIVA” problem.
DIVA is short for “differentiating infected from vaccinated animals” — the challenge of identifying whether a bird is actually infected with avian influenza, or just has avian influenza antibodies after vaccination. Countries fear that importing eggs or slaughtered meat from vaccinated birds in countries where the virus is circulating could inadvertently spread it within their own borders by introducing the virus to wild or domesticated animals through discarded raw meat. That means that big poultry exporters like the US — which sends 18 percent of its poultry abroad — don’t vaccinate, for fear they’ll miss out on a huge part of their revenue: international trade.”
…
“without international coordination and predictable vaccine use, it doesn’t make economic sense for vaccine makers to invest in developing vaccines that protect against the bird flu. “We’re not going to make [massive investments] unless we’ve got major markets on board,” said du Marchie Sarvaas. “And the only way you’re going to get major markets on board is if you get some sort of political deal. And that comes to the trade point and the export point.””
…
“It’s also a geopolitical coordination challenge, a classic game theory problem where no major poultry-producing country wants to be the first to vaccinate. As a result, everyone sticks with the kill ’em all approach.”
