Two batches of raw milk from a trendy California brand have tested positive for bird flu this week.
Bird flu has been spreading rapidly among cattle in the US.
Experts say drinking raw milk is dangerous, and can cause food poisoning.
Another batch of raw milk just tested positive for bird flu in California.
Last Sunday, Fresno-based Raw Farm voluntarily recalled a first batch of cream top whole raw milk with a “best by” date of November 27. By Wednesday, the California Department of Public Health announced that a second batch of Raw Farm cream top, with a “best by” date of December 7 had also tested positive for bird flu, based on retail sampling.
“We’re not making a big deal about it, because it’s not a big deal,” Kaleigh Stanziani, Raw Farm’s vice president of marketing, said in a short video posted on YouTube after the farm’s first voluntary recall was announced earlier this week.

She said there had only been an indication that there might be a “trace element of something possible,” emphasizing that there had been no reported illnesses of Raw Farms cows or positive tests from the cattle.
Raw Farm owner Mark McAfee later told the LA Times that the California Department of Food and Agriculture had requested that his company “hold delivery of further products” until Friday, after conducting thorough testing of two Raw Farms and one creamery on Wednesday. (McAfee could not immediately be reached for comment by Business Insider during the Thanksgiving holiday.)
Raw milk may be helping bird flu spread — but not in the way you might think

Scientists suspect that cross-contamination of raw milk between animals may be one reason the H5N1 virus is spreading rapidly among cows in the US — and could even contribute to the human spread of the virus. The Centers for Disease Control and Prevention cautions that dairy workers might be able to contract bird flu by infected raw milk splashed into their eyes.
There is no definitive evidence yet that humans can get bird flu from drinking contaminated raw milk. Instead, health authorities generally recommend avoiding raw milk because of other serious health risks, including food poisoning with bacteria like Salmonella, E.coli, or Listeria.
There are no known health benefits of drinking raw milk. Instead, all evidence suggests that pasteurized milk is just as nutritious, and is safer to consume.
Still, raw milk has become a trendy product among some influencers. Gwenyth Paltrow says she has it in her coffee in the morning.

Robert F. Kennedy Jr., President-elect Trump’s pick for Health and Human Services secretary, says he wants the US Food and Drug Administration to stop its “war” against raw milk.
Over the summer, “Carnivore MD” Paul Saladino released a raw milk smoothie in partnership with the elite Los Angeles health foods store Erewhon featuring unpasteurized (raw) kefir from Raw Farms, and powdered beef organs.
California has some of the loosest rules around raw milk in the country; it’s generally fine for California retailers like health foods stores and grocers to sell it, raw milk products just can’t be transported across state lines, per FDA rules.
Dr. Paul’s Raw Animal-Based Smoothie includes Raw Farm kefir milk, beef organ powder, as well as blueberries, honey, bananas and other ingredients. It’s $19.

Michael Payne, a researcher at the Western Institute of Food Safety and Security, told The Guardian that people consuming Dr. Paul’s $19 smoothie were “playing Russian roulette with their health,” and ignoring pasteurization, “the single most important food safety firewall in history.”
California dairy farms have been seeing an uptick in bird flu cases since August. The state has reported 29 confirmed human cases of bird flu, and all but one of those was sourced back to cows.
Last week, the Centers for Disease Control and Prevention reported the first confirmed case of bird flu in a California child from Alameda County. The child had no known contact with infected farm animals, but may have been exposed to wild birds, the California health department said in a statement.

The child had mild symptoms and is recovering well after receiving antiviral drugs.
California air quality officials have sued four truck manufacturers for breaching a voluntary agreement to follow the state’s nation-leading emissions rules, the state announced Tuesday.
What happened: Attorney General Rob Bonta’s office filed a complaint Monday in Alameda County Superior Court, arguing that the country’s four largest truck-makers — Daimler Truck North America, International Motors, Paccar and Volvo North America — violated an enforceable contract that they signed with the California Air Resources Board in 2023.
The lawsuit comes two months after the manufacturers filed their own complaint in federal court, arguing the agreement — known as the Clean Truck Partnership — is no longer valid after Republicans overturned California’s Advanced Clean Truck rule in June through the Congressional Review Act.

Why it matters: The move sets up a fight to determine whether the federal system or state courts — where CARB would have a higher likelihood of prevailing — will review the case.
California, along with other states, has filed a lawsuit against the U.S. Department of Agriculture and Secretary Brooke Rollins for halting SNAP benefits, cutting off food aid for over 41 million Americans, according to Attorney General Rob Bonta.
About 85% of elementary schools studied in California experienced some loss of trees between 2018 and 2022, according to a paper from the University of California, Davis, published this month in the journal Urban Forestry and Urban Greening.
Members of the UC Davis Urban Science Lab found that while the average decline was less than 2%, some districts in the Central Valley — including schools with few trees to lose — lost up to a quarter of their tree cover. The most severe losses were concentrated in Tulare County, while the most notable gains were found in Imperial County.

The findings are troubling as climate change will likely intensify extreme heat and drought conditions. The study underscores an urgent need to improve tree canopy in low-shade, high-need schools and to protect existing tree cover in areas facing loss.
“We are trying to measure to what extent we are exposing kids to temperatures that might be stressing their body to a level that becomes uncomfortable or dangerous,” said Alessandro Ossola, an associate professor of plant sciences who directs the Urban Science Lab at UC Davis.

The team continued the research this past summer at elementary schools across the state, measuring tree canopies and maximum temperatures at playgrounds, basketball courts, soccer fields and other outdoor spaces.

Tree canopies cover only about 4% to 6% of the average California school campus. That means the roughly 5.8 million K-12 public school students in California often take breaks and participate in outdoor activities under the glaring sun.
As part of the work, researchers mapped tree cover and heat over the course of a hot day at schools in inland and coastal areas of Northern and Southern California.

The research is a joint effort with UC Davis, UC Berkeley and UCLA and is funded by the U.S. Forest Service and supported by the nonprofit Green Schoolyards America through its California Schoolyard Tree Canopy study.
“Most schools are actually a nature desert, which is antithetical because we know that early life exposure of humans to nature is critical for them to develop skills, improve their microbiome, become more environmentally active and so on,” Ossola said. “Trees are a hidden asset and an underutilized asset.”
