About five miles south of Broken Bow, in the heart of central Nebraska, thousands of cattle stand in feedlots at Adams Land & Cattle Co., a supplier of beef to the meat giant Tyson Foods.

From the air, the feedlots look dusty brown and packed with cows—not a vision of happy animals grazing on open pastureland, enriching the soil with carbon. But when the animals are slaughtered, processed, and sent onward to consumers, labels on the final product can claim that they were raised in a “climate friendly” way.

In late 2022, Tyson—one of the country’s “big four” meat packers—applied to the US Department of Agriculture (USDA), seeking a “climate friendly” label for its Brazen Beef brand. The production of Brazen Beef, the label claims, achieves a “10 percent greenhouse gas reduction.” Soon after, the USDA approved the label.

Immediately, environmental groups questioned the claim and petitioned the agency to stop using it, citing livestock’s significant greenhouse gas emissions and the growing pile of research that documents them. These groups and journalism outlets, including Inside Climate News, have asked the agency for the data it used to support its rubber-stamping of Tyson’s label but have essentially gotten nowhere.

“There are lots of misleading claims on food, but it’s hard to imagine a claim that’s more misleading than ‘climate friendly’ beef,” said Scott Faber, a senior vice president at the Environmental Working Group (EWG). “It’s like putting a cancer-free label on a cigarette. There’s no worse food choice for the climate than beef.”

The USDA has since confirmed it is currently considering and has approved similar labels for more livestock companies, but would not say which ones.

On Wednesday, the EWG, a longtime watchdog of the USDA, published a new analysis, outlining its efforts over the last year to push the agency for more transparency, including asking it to provide the specific rationale for allowing Brazen Beef to carry the “climate friendly” label. Last year, the group filed a Freedom of Information Act request, seeking the data that Tyson supplied to the agency in support of its application, but received only a heavily redacted response. EWG also petitioned the agency to not allow climate friendly or low carbon claims on beef.

To earn the “climate friendly” label, Tyson requires ranchers to meet the criteria of its internal “Climate-Smart Beef” program, but EWG notes that the company fails to provide information about the practices that farmers are required to adopt or about which farmers participate in the program. The only farm it has publicly identified is the Adams company in Nebraska.

A USDA spokesperson told Inside Climate News it can only rely on a third-party verification company to substantiate a label claim and could not provide the data Tyson submitted for its review.

“Because Congress did not provide USDA with on-farm oversight authority that would enable it to verify these types of labeling claims, companies must use third-party certifying organizations to substantiate these claims,” the spokesperson wrote in an email, directing Inside Climate News to the third-party verifier or Tyson for more information.

The third-party verification company, Where Food Comes From, did not respond to emailed questions from Inside Climate News, and Tyson did not respond to emails seeking comment.

The USDA said it is reviewing EWG’s petitions and announced in June 2023 that it’s working on strengthening the “substantiation of animal-raising claims, which includes the type of claim affixed to the Brazen Beef product.”

The agency said other livestock companies were seeking similar labels and that the agency has approved them, but would not identify those companies, saying Inside Climate News would have to seek the information through a Freedom of Information Act request.

“They’re being incredibly obstinate about sharing anything right now,” said Matthew Hayek, a researcher with New York University who studies the environmental and climate impacts of the food system. “Speaking as a scientist, it’s not transparent and it’s a scandal in its own right that the government can’t provide this information.”

This lack of transparency from the agency worries environmental and legal advocacy groups, especially now that billions of dollars in taxpayer funds are available for agricultural practices deemed to have benefits for the climate. The Biden administration’s signature climate legislation, the Inflation Reduction Act, appropriated nearly $20 billion for these practices; another $3.1 billion is available through a Biden-era program called the Partnership for Climate-Smart Commodities.

“This is an important test case for USDA,” Faber said. “If they can’t say no to a clearly misleading climate claim like ‘climate friendly’ beef, why should they be trusted to say no to other misleading climate claims? There’s a lot of money at stake.”

We still don’t understand how one human apparently got bird flu from a cow

The US Department of Agriculture this week posted an unpublished version of its genetic analysis into the spillover and spread of bird flu into US dairy cattle, offering the most complete look yet at the data state and federal investigators have amassed in the unexpected and worrisome outbreak—and what it might mean.

The preprint analysis provides several significant insights into the outbreak—from when it may have actually started, just how much transmission we’re missing, stunning unknowns about the only human infection linked to the outbreak, and how much the virus continues to evolve in cows. The information is critical as flu experts fear the outbreak is heightening the ever-present risk that this wily flu virus will evolve to spread among humans and spark a pandemic.

But, the information hasn’t been easy to come by. Since March 25—when the USDA confirmed for the first time that a herd of US dairy cows had contracted the highly pathogenic avian influenza H5N1 virus—the agency has garnered international criticism for not sharing data quickly or completely. On April 21, the agency dumped over 200 genetic sequences into public databases amid pressure from outside experts. However, many of those sequences lack descriptive metadata, which normally contains basic and key bits of information, like when and where the viral sample was taken. Outside experts don’t have that crucial information, making independent analyses frustratingly limited. Thus, the new USDA analysis—which presumably includes that data—offers the best yet glimpse of the complete information on the outbreak.

Undetected spread

One of the big takeaways is that USDA researchers think the spillover of bird flu from wild birds to cattle began late last year, likely in December. Thus, the virus likely circulated undetected in dairy cows for around four months before the USDA’s March 25 confirmation of an infection in a Texas herd.

This timeline conclusion largely aligns with what outside experts previously gleaned from the limited publicly available data. So, it may not surprise those following the outbreak, but it is worrisome. Months of undetected spread raise significant concerns about the country’s ability to identify and swiftly respond to emerging infectious disease outbreaks—and whether public health responses have moved past the missteps seen in the early stages of the COVID-19 pandemic.

But another big finding from the preprint is how many gaps still exist in our current understanding of the outbreak. To date, the USDA has identified 36 herds in nine states that have been infected with H5N1. The good news from the genetic analysis is that the USDA can draw lines connecting most of them. USDA researchers reported that “direct movement of cattle based upon production practices” seems to explain how H5N1 hopped from the Texas panhandle region—where the initial spillover is thought to have occurred—to nine other states, some as far-flung as North Carolina, Michigan, and Idaho.

[/ars_img]The bad news is that those lines connecting the herds aren’t solid. There are gaps in which the genetic data suggests unidentified transmission occurred, maybe in unsampled cows, maybe in other animals entirely. The genetic data is clear that once this strain of bird flu—H5N1 clade 2.3.4.4 genotype B3.13 —hopped into cattle, it could readily spread to other mammals. The genetic data links viruses from cattle moving many times into other animals: There were five cattle-to-poultry jumps, one cattle-to-raccoon transmission, two events where the virus moved from cattle to domestic cats, and three times when the virus from cattle spilled back into wild birds.

“We cannot exclude the possibility that this genotype is circulating in unsampled locations and hosts as the existing analysis suggests that data are missing and undersurveillance may obscure transmission inferred using phylogenetic methods,” the USDA researchers wrote in their preprint.
