Radioactive pollution still haunts Hunters Point in San Francisco
San Francisco — More than a half century after the U.S. ignited 67 atomic weapons in the the central Pacific Ocean, a former Navy base in the Bay Area continues to carry that nuclear legacy.
Last week, residents were informed by the San Francisco Department of Health that a test taken in November 2024 at the former site of Hunters Point Naval Shipyard showed radiation levels of airborne Plutonium-239 had exceeded the Navy’s “action level,” requiring the military to further investigate.
The city and the residents were not informed until 11 months after that initial reading.
Hunters Point, a 500-acre peninsula jutting out into San Francisco Bay, served as a military laboratory to study the effects of nuclear weapons from 1946-69 following World War II. Although the research largely focused on how to decontaminate U.S. warships and equipment targeted with atomic bombs, the experimentation left much of the shipyard laced with radioactive contaminants and toxic chemicals.
For the last 30 years, the Navy has sought to clean up the area — now a U.S. Superfund site — with the long-term goal of redeveloping it into new housing and parkland.
But some Bay Area community leaders say haphazard remediation work and lackluster public outreach have endangered the health and safety of residents of the Bayview-Hunters Point neighborhood that sits beside the former shipyard. And they point to the Navy’s nearly year-long delay in informing them of the elevated Plutonium-239 reading, taken in November 2024, as just the latest example.
Plutonium-239 is a radioactive isotope and byproduct of nuclear bomb explosions. The elevated readings from November 2024 came from a 78-acre tract of land on the northeast portion of the shipyard, known as Parcel C.
“The City and County of San Francisco is deeply concerned by both the magnitude of this exceedance and the failure to provide timely notification,” wrote San Francisco Health Officer Susan Philip in an Oct. 30 letter to Navy officials. “Such a delay undermines our ability to safeguard public health and maintain transparency. Immediate notification is a regulatory requirement and is critical for ensuring community trust and safety.”
Navy officials and some health experts insist the radiation levels detected at the site, while above the Navy’s action level, did not pose an imminent or substantial threat to public health. Exposure to this level of Plutonium-239 every day for one year would be less than one-tenth the dose of radiation from a chest X-ray, according to a Navy spokesperson.
“The San Francisco Department of Public Health’s letter references a single outlier air sample that detected Plutonium-239 above the regulatory action level,” a Navy spokesperson said in a statement to The Times. “Regulatory action levels are deliberately and conservatively established below levels of health concern, and a single detection of Pu-239 at this level does not pose a risk to human health or public safety.”
The Navy said it has collected more than 200 ambient air monitoring samples from Parcel C since it began performing fieldwork there in 2023. The November 2024 sample was the only reading with elevated Plutonium-239, the Navy spokesperson told The Times.
Plutonium isotopes emit alpha radiation that is relatively benign outside the body, because it cannot travel through solid objects. However, if these radioactive particles are inhaled, they can damage the lungs and increase the long-term risk of developing certain cancers, according to the Centers for Disease Control and Prevention.
“What we generally are concerned about for alpha emitters is if you get them into your body, and either through inhalation, ingestion, inadvertent injection — like somebody gets a cut and it gets into their body,” said Kathryn Higley, a professor of nuclear science at Oregon State University.
But it’s the lack of transparency and the 11-month delay in reporting the reading that has fomented community mistrust and raised questions regarding the military’s competency to safely clean up the polluted shipyard. In 2000, the EPA admonished naval officials for neglecting to inform residents that a fire had broken out at a hazardous landfill at Hunters Point. In 2017, two employees of the consulting firm Tetra Tech, who were hired by the Navy to assess radiation levels at Hunters Point, pleaded guilty to falsifying data in an effort to avoid having to perform additional cleanup on some areas of the shipyard.
The presence of radioactive air contaminants — at any level — compounds the health risks of the Bayview-Hunters Point neighborhood, which already faces high exposure to toxic diesel particles from big rigs traveling on nearby freeways and cargo ships visiting the Port of San Francisco.
Hunters Point Biomonitoring Foundation, a local nonprofit, has found concerning levels of toxic substances in urine screenings it has provided to several residents of the neighborhood, especially among older individuals and those living closer to the former Naval shipyard.
“Now, you’re talking about adding one of the most devastating radionuclides known to the human cardiopulmonary system to the chemical burden,” said Dr. Ahimsa Porter Sumchai, the foundation’s medical director and principal investigator.
“The particulate load is enough to kill people,” Sumchai added. “But you add … a little Plutonium-239, and it’s a recipe for death.”
Philip, the San Francisco health officer, said in a statement that she met with Navy officials Oct. 31 and received assurances that air and dust monitoring is “ongoing” and that the military agency is “reviewing their duct control methods to ensure they are fully protective of public health.”
As a result, “no immediate action is required from a public health safety standpoint,” she said, adding that her office will continue to closely monitor the situation.
Other experts argued the situation was overblown. Phil Rutherford, a radiological risk expert and corporate consultant, called the delayed notification “unacceptable” but said the San Francisco health department’s letter was “a storm in a teacup” considering the low levels of radioactive material.
Higley, the Oregon State professor, said the site’s long history of delays and scandals likely added to backlash from community members. “I understand [residents’] frustration that they want to see this place cleaned up so that they can safely use it,” Higley said. “And there’s been a lot of reasons for why this process takes so long. But, from a radiological perspective, the actual residual radioactivity at the site is pretty modest.”
In November 2024, a Navy contractor was grinding asphalt on the site — a construction project that, while unrelated to the site’s historical contamination, triggered the Navy to monitor for any air quality issues. One of its air samplers, in Parcel C — collected 8.16 times 10‐15 picocuries per milliliter of Plutonium-239 — twice the established action level — according to a Navy spokesperson.
Navy officials sent the sample to a lab for analysis, and the initial results came back in March 2025, showing high radiation levels. In April, they ordered the lab to reanalyze the sample. In the follow-up analysis, radiation levels of Plutonium-239 were below action levels.
Between May and September, the Navy “further investigated the test results and conducted a methodical review of the laboratory’s procedures and practices to ensure they complied with standards,” according to the Navy spokesperson. “A third party also conducted an analysis of the lab’s performance.”
Later that September, the Navy told the U.S. Environmental Protection Agency and several California state agencies about the elevated airborne radiation from Plutonium-239, in preparation for an upcoming community meeting. That information later trickled down to the San Francisco health department.
At some point, the Navy published some air quality data for Parcel C gathered between October and December 2024 on a website where it curates several environmental monitoring reports. That report only showed the lower Plutonium-239 radiation levels from the reanalysis were below the action level.
A Navy spokesperson told The Times that it was “mistakenly uploaded.”
“As soon as the Navy realized an incomplete report was uploaded, it was removed from the website,” the spokesperson said, while the Navy worked to verify the results.
All that has contributed to the confusion and concern among locals and advocates alike. Navy officials are expected to attend a Hunters Point Shipyard Citizens Advisory Committee Meeting on Nov. 17.
When fieldwork is occurring at the shipyard, the Navy monitors for Plutonium-239 and several other radioactive elements that may have resulted from historic fallout from atomic weapons testing.
Acquired by the Navy in 1940, Hunters Point was initially a base where ships were built, repaired and maintained during World War II. After the war ended, it became home to the Navy Radiological Defense Laboratory, a military research facility dedicated to investigating the effects of nuclear weapons and radiological safety.
The Navy bombarded a fleet of U.S. warships with nuclear weapons as a part of atomic testing in the Marshall Islands. The irradiated vessels were towed to Hunters Point, and used as the material and hardware upon which scientists tested decontamination methods.
In 1974, the shipyard was deactivated. Hazardous chemicals and low-level radiological contamination were identified, prompting the U.S. EPA to place the site on its Superfund list in 1989.
The Navy has led cleanup efforts, excavating contaminated soil and demolishing buildings. A largely residential parcel of the base, Parcel A, was turned over to San Francisco and has been redeveloped with new town houses and condos. A collective of 300 artists live and work in former naval buildings.
But dangers continue to emerge during ongoing remediation work.
In recent years, the Navy has recovered radioactive objects, including dials and deck markers coated with paint containing Radium isotopes to provide a glow-in-the-dark effect. Sumchai, medical director of the biomonitoring foundation, said she has observed large stockpiles of contaminated soil held in areas without any protective fencing to prevent contaminants from spreading off site.
“I view this as a local public health emergency,” Sumchai said. “I think that everything should be done to contain it and to remove people safely, if necessary, from documented areas of exposure.”
But to the casual observer the site looks unremarkable.
Hunters Point juts out into the San Francisco Bay just north of where Candlestick Park, the former home of the San Francisco Giants and 49ers, used to stand. Beyond the abandoned barracks and drydocks, the site is now mostly an empty expanse of grass and reeds, with an unobstructed view of the bay.
The cleanup sites, including Parcel C, are still fenced off, and only those with authorized credentials are allowed onto the property.
On a recent weekday afternoon, ravens flew and cawed over the long-vacant shipyard buildings, while construction crews and trucks ferried building equipment up and down Hill Drive — a steep road leading to brand new homes standing sentinel over the former shipyard.
And beyond waiting for a new batch of Navy reports, there was no way of knowing what’s in the air.

5 Great Stargazing Trains
Stargazing, it turns out, doesn’t have to be a stationary activity.
On railway lines around the world, from the Arctic Circle to New Zealand, a select set of evening train excursions take riders deep into dark-sky territory — some en route to remote station stops decked out with telescopes, others featuring onboard astronomers.
These five rail journeys (all of which are accessible) range from two- to three-hour desert outings to a hunt for the northern lights. One route even has a planetarium on rails. All promise a renewed appreciation of train travel — and of our pale blue dot’s improbable place in the cosmos.
Nevada
The Great Basin Star Train
Any stargazing train worth its salt requires one thing: a dark sky. The Star Train resoundingly checks that box, traveling through a part of eastern Nevada that is one of the least-populated places in the lower 48.
Run by the Nevada Northern Railway in partnership with nearby Great Basin National Park, the train departs the historic East Ely Depot, in Ely, Nev., early enough in the evening to catch the sunset over the Steptoe Valley, and then cruises through darkening skies to its destination: a remote corner of the desert appropriately called Star Flat, where a stargazing platform outfitted with telescopes awaits. There, riders disembark (equipped with red-light necklaces to help preserve their night vision) and take turns viewing the cosmos, guided by professional astronomers. (Last year’s onboard stargazing guides came from Caltech; in previous seasons, the National Park Service’s Dark Rangers, who specialize in night-sky activities, accompanied trips.)
The Star Train makes its two-and-a-half-hour round-trip journey most Friday evenings between mid-May and mid-September, and tickets ($65 for adults) can sell out almost a year in advance — though members of the Nevada Northern Railway Museum get early access. Alternatively, the railroad’s more frequent Sunset, Stars and Champagne excursions trade telescopes for desert sundowners but feature the same expert stargazers and the same Nevada night sky, which is often dark enough to see the Milky Way with the naked eye.
New Mexico
The Stargazer
While plenty of heritage railroads across the United States offer twilight rides and nighttime excursions, at the moment there’s only one other dedicated, regularly scheduled stargazing train in North America besides the Star Train: the Stargazer, operated by Sky Railway, in Santa Fe, N.M.
Much like its Nevada counterpart, the Stargazer makes a two-and-a-half-hour round trip through dark-sky country, though in this case, the journey really is the destination, because it doesn’t make any stops. More of a rolling night-sky revue, the Stargazer features live music and professional astronomers who share their celestial knowledge and stories as the train rumbles into the vast Galisteo Basin south of Santa Fe. Sky Railway’s colorfully painted trains feature heated, enclosed passenger cars to stave off the evening chill and flatbed cars open to the night sky.
Departing from the Santa Fe Depot downtown, the train normally runs once a month (adult tickets from $139, including a champagne welcome toast). Sky Railway also occasionally schedules excursions for special celestial events.
New Zealand
Matariki Rail Experience
With its alpine landscapes and rugged coastline, New Zealand’s South Island is practically tailor-made for scenic daytime train journeys. But when night falls, the sparsely populated island — home to the Southern Hemisphere’s largest International Dark Sky Reserve — is heaven for stargazers, too.
This year, Great Journeys New Zealand, which operates the country’s tourist-centric long-distance trains, is offering a special nighttime run of the Coastal Pacific, whose route skirts the South Island’s northeastern coast. Timed to Matariki, the Maori new year, which is heralded by the first rising of the Pleiades star cluster, the eight-hour round trip from Christchurch is a cultural and astronomical celebration.
After the first half of a four-course onboard dinner, the train arrives in Kaikoura, in dark-sky country, for a guided stargazing stop with a range of telescopes — and fire pits and a night market. (The rain plan involves a virtual stargazing session at the local museum using virtual reality headsets.) Dinner resumes back on the train as it returns to Christchurch. This is a strictly limited engagement, on the rails for one night only: July 11, for 499 New Zealand dollars, about $295, per person.
In the far northern reaches of Norway, inside the Arctic Circle, you can ride a train that chases another wonder of the night sky: the aurora borealis. Twice a week from October to March, the Northern Lights Train takes its riders into the dark polar night in pursuit of the aurora’s celestial light show.
From the remote town of Narvik, the train travels along the Ofoten Railway, the northernmost passenger rail line in Western Europe. The destination on this three-hour round-trip excursion (1,495 kroner, or about $160) is Katterat, a mountain village accessible only by rail and free of light pollution, making it an ideal place to spot the aurora. At the Katterat station, local guides and a campfire cookout await, as does a lavvu, the traditional tent used by the Sami people of northern Scandinavia, offering a respite from the cold (as well as hot drinks and an open fire for roasting sausages).
And aboard the train, the lights stay off, which means that on a clear night, you might even catch the northern lights on the way there and back.
Leave it to Japan to take the stargazing train to another level.
The High Rail 1375 train — so named because it runs along Japan’s highest-elevation railway line (the high point is 1,375 meters, or roughly 4,500 feet, above sea level) — is one of JR East’s deliberately unhurried Joyful Trains, which the railway company describes as “not only a means of transportation, but also a package of various pleasures.” This astronomy-themed train certainly packs plenty of joy into its two cars, with seat upholstery inspired by constellations, a snack bar, a souvenir shop and a planetarium car with a library of astronomy books and images of the night sky projected onto its domed ceiling.
The train makes two daytime runs along the mountainous Koumi Line, taking a little over two hours to travel between Kobuchizawa (accessible by express train from Tokyo) and Komoro. But the main event is the High Rail Hoshizora (“Starry Sky”) evening trip, which includes an extended stop at Nobeyama Station (the highest in the country) for a guided stargazing session. A one-way ride on High Rail 1375, which runs on weekends and occasional weekdays, requires a seat reservation if you’re traveling on a Japan Rail pass, or a stand-alone ticket plus seat reservation (2,440 yen, or about $15). And remember to preorder a special “Starry Sky” bento box.

A Physicist Who Thinks in Poetry from the Cosmic Edge
Much of the praise for Chanda Prescod-Weinstein’s debut book in 2021, “The Disordered Cosmos: A Journey Into Dark Matter, Spacetime, and Dreams Deferred,” lauded the way she used personal experiences in physics to discuss the social and political inequities that exist alongside scientific breakthroughs.
“It contains the narrative of dreams deferred,” Dr. Prescod-Weinstein, a physicist at the University of New Hampshire, explained in April at a bookstore in Chicago. But its very existence, she said, also “represented a dream deferred, because that was not the dream of what my first book was going to be.”
Her second book reclaims that dream. Released on April 7, “The Edge of Space-Time: Particles, Poetry, and the Cosmic Dream Boogie” is less pain and more play, a homage to the big questions that made Dr. Prescod-Weinstein want to become a physicist in the first place. She begins the book by asserting that it is humanity’s duty to uncover and share the story of our universe. Her latest offering toward that duty is a journey through physics that is tightly bound to her own cultural roots.
In the midst of a multicity book tour, Dr. Prescod-Weinstein spoke with The New York Times about guiding readers through the cosmos from her own point of view and about some of the art, poetry and literature she drew on to shape that journey. This conversation has been edited for brevity and clarity.
Why include so many references to poetry in a book about physics?
I knew poetry before I knew physics. It was part of my upbringing. I loved A.A. Milne’s “Now We Are Six” and Edward Lear’s “Nonsense Limericks.” Both of my books draw their subtitles from Langston Hughes’s “Montage of a Dream Deferred.”
Adrienne Rich’s poem “The Burning of Paper Instead of Children” became a guiding light for how my work would move in the world. It also opened up for me that I need language. That’s true among physicists. Even an equation is a sentence; even an equation is telling a story.
As physicists, we’re always working in language to connect what we learn with what we know. Poetry is one of the first places that my brain goes to draw those links. Language, as it moves in my brain, is often in Hughes and Rich and Shakespeare. Those are the lines that flicker up for me.
What if we got away from the argument that doing cosmology and particle physics is practical or materially valuable? Then we have to accept that we’re like the poets. What we do is important culturally in the same way poetry is. A piece of this book is me saying there is value in banding with the poets, and fighting for the value of being curious and trying to articulate the world with whatever tools are available to us. Not for the purposes of selling something, but for the purpose of fulfilling our humanity.
Another theme throughout the book is the story of Lewis Carroll’s Alice and her adventures in Wonderland.
Being a science adviser on future installments in The Legendborn Cycle, a fantasy series written by Tracy Deonn, is one reason Alice is in my book. It has allowed me to be open to the playful side that physics, as a Black queer person, can take from you. I wanted the book to be whimsical, because that’s who I was when I first arrived in physics, and that’s who I want to be when I die.
Part of the call of quantum physics is to change what our sense and sensibility are. When you look at the world through this framework — like the idea that particles have spin but don’t really spin — it sounds like nonsense. Except that’s literally how the universe works. Physics is our “through the looking glass.” It’s real.
Your first chapter invites readers to reflect on the metaphors used to describe the universe, like the “fabric” of space-time or electromagnetic “fields.” Why open in this way?
A lot of books about quantum physics start with its history. I wanted as much as possible not to just do that. I had actually planned to start it with the Stern-Gerlach experiment of 1922. But then I read an essay by the poet Natasha Trethewey about abiding metaphors and started to ask myself what the abiding metaphors of my physics training were.
We don’t ever take time in our classes to ask, “What do we mean when we say ‘space’? What do we mean when we say ‘space-time’?” There are these metaphysical questions that I often told myself were for the philosophers. This book was me letting myself think of them as physics.
One metaphor you invoke is the “edge” — not only the edge of the universe and of scientists’ understanding, but also existing at the edge of certain identities.
In “Disordered Cosmos,” I talked a lot about being at the margin and looking toward the center. With “The Edge of Space-Time,” I’m choosing to make the margin the center of the story. Part of that was me fully embracing what makes me the physicist I am. I’m an L.A. Dodgers fan. I love “Alice in Wonderland.” I love “Star Trek.” There’s lots of all of that in the book.
Picking a metaphor is a culturally situated decision. I wrote a line that says black holes are the best laid edges in the universe. I did, at some point, think that only some people were going to get this. But for people who don’t understand the reference to Black hairstyles, the sentence is still legible. And for those who do, it will feel like we just had an in-group moment. Anyone who thinks about laying their edges deserves to have an in-group moment in a physics book. Because we are physics, too.
Black students are often told that if you want to be a physicist, then you will make yourself as close to such-and-such mold as possible. At a young age, we have this understanding that whiteness and science are associated with each other, but we are also witnessing in ourselves that this can’t be entirely correct. There’s this narration of, “Well, sure, you can be Black in physics, but that means you have to acclimate to the ‘in physics’ part, and never that physics has to acclimate to the Black part.”
I use the example of rapper Big K.R.I.T.’s song “My Sub Pt. 3 (Big Bang),” in which someone tries to wire up subwoofers in his car but fries the wires because he doesn’t ground them properly. I don’t know if Big K.R.I.T. would think of this as a science story, but I think we should learn to read it as one. Not to contain it in science, but to say it overlaps there. This can be a rap song. It can be about the cultural significance of subwoofers and the Big Bang as a metaphor for the beat. And it can also be about cosmology and about how everybody who wires up cars or does this kind of work is a scientist, too.
How do you want readers to approach this book?
There is this feeling that you’re supposed to read a book like this and walk away an expert. That’s actually not the point of this book at all. The point is to wander through physics. Even if math terrifies you, you are entitled to spend some time with it.
And so here, I have made you a book with a bunch of tidbits on the oddities of the universe. The universe is stranger and more queer and more wonderful and more full of possibility than whatever limitations you might be experiencing right now. Physics challenges what we are told are social norms. For example, non-trinary neutrinos are fundamental to our standard model of physics.
“Non-trinary,” as in they shift between three different forms.
Non-trinary is natural. It’s such a challenge to the current anti-trans rhetoric that says people can only ever be one thing.
I don’t need my book to be the most important thing that someone reads. But I want it to be a source of hope. If it reminds you that, as my mom says, the universe is bigger than the bad things that are happening to us, then that’s all you need to remember. I’m good with that.

Footage shows Central Valley dairy workers kicking young calves, pulling them with pliers
In late February, animal rights activists flew a drone over a calf ranch in the Central Valley and watched as workers kicked and punched the animals.
For the record:
7:15 p.m. May 12, 2026This article has been updated to reflect that no calves from Agresti Calf Ranch have ever gone on to be used for Clover Sonoma milk supplies, and the calf ranch opened only in 2025. In additional comments, Clover Sonoma also said in the future, no animals from Agresti Calf Ranch will be part of its supply.
Footage reviewed by The Times shows a worker pulling a calf by the nose with pliers.
It shows two workers removing the budding horns of a calf with a hot iron. While one held the frightened animal’s head, the other — wearing a sweatshirt with an image of the Virgin Mary — applied the iron to a horn. After a puff of smoke, the calf fell to its side, appearing motionless.

Both male and female calves produce horns. To prevent injury to the animals and their handlers, these are commonly removed. Humane guidelines require anesthesia.
The footage was collected by the group Direct Action Everywhere, known for tactics including releasing beagles from medical breeding facilities and abused calves from farms. It was shot at the Agresti Calf Ranch in Ceres, near Modesto, which is certified by the American Humane Society for its ethical treatment of animals. The workers could not be reached for comment. One was subsequently terminated, the Humane Society said.
The Agresti Calf Ranch opened in 2025 and is operated by the owners of Double D Dairy, just up the road. Double D Dairy owns more than 10,000 cows across several operations.
The owner of Double D, Dominic Assali, declined to answer questions in person. A phone number for the dairy online is disconnected. In response to an email to his personal account, Assali said, “Animal welfare and safety are incredibly important to us, and we have a zero-tolerance policy for any mistreatment.
“We’ll always take immediate, thorough action to address any operational issues, as we have in this instance,” the email said.
The American Humane Society is a 150-year-old nonprofit focused on animal welfare. Among other things, it certifies animal safety on farms as well as on movie sets. In a statement, it said only 10% of animals raised on farms in the U.S. are certified as humanely treated.
Assali is the grandson of the farm’s founders, Harold and Marlene Agresti. He is a board member of Western United Dairies, the largest dairy trade group in California.
The mistreatment captured on video has also created a headache for a prominent California sustainable milk brand, Clover Sonoma, based in Sonoma County.
It gets 10% to 15% of its milk from Double D, and Assali and his family are featured on Clover Sonoma’s website. No calves from Agresti Calf Ranch have ever gone on to be used in Clover Sonoma milk supplies, the company said in a statement. It’s unclear whether the abused calves were being raised for beef or dairy.
A Clover Sonoma sign hung outside the main dairy complex on a recent visit.
Clover Sonoma markets its milk, yogurt and cheese products as humanely sourced and environmentally sound. It was the first dairy company to receive a cruelty-free certification from the American Humane Society in 2000. The website also features a “Our Promise” page, which states the company demands “the humane treatment of animals.”
“We were deeply concerned by the reported mistreatment of some cows captured on video at Agresti Calf Ranch during a separate cow operation,” the company said in an email.
“The rough handling shown at Agresti Calf Ranch is contrary and inconsistent with the humane practices we have fostered for decades and which we demand of all our suppliers.”
Clover Sonoma said it suspended business with Double D as soon as it became aware of the incidents and began “a rigorous audit,” which just ended.
“Clover and the American Humane Society have concluded that the mistreatment was an isolated issue, not systemic or reflective of Agresti Calf Ranch’s personnel. Corrections have been made, including the termination of the employee in the video. As such, we are comfortable reinstating the milk from Double D Dairy.”
After this story published, Clover went further and said a condition of Double D’s reinstatement will be that no animals from Agresti Calf Ranch will be part of Clover’s dairy supply.
A statement from the Humane Society said Clover Sonoma is working with Double D to strengthen its whistleblower policy and training, and has “reiterated its commitment to ongoing independent, third-party audits,” with both announced and unannounced visits.
Clover Sonoma mainly buys and processes milk from dairies in verdant Sonoma County, as the company’s marketing suggests. Double D Dairy is one of its few suppliers in the Central Valley, which is associated more with industrial-scale agriculture.
On a recent weekday, the calf ranch and dairy farm were visible from a public road. Holstein calves, a popular dairy breed, could be seen in cages through small trees in front of the enclosures. The sound of mooing and a pressure washer could be heard. The smell of manure and dirt wafted in the humid air.
Most dairy companies remove calves from their mothers after birth, raising them separately so they don’t take the mother’s commercially valuable milk. Some dairy farms send calves out to third-party calf ranches for rearing. Others raise them on-site. Female calves are typically raised to become milk cows. Male calves are sent away to become beef or other meat-based products, such as pet food.
A 2025 State Water Board document shows the farm houses an average of 700 calves at any one time, with a maximum 1,400.
The Direct Action Everywhere activists were recently on a public road near Double D’s main farm, flying a drone over the property. Within 30 minutes of their arrival, seven Stanislaus County sheriff’s vehicles arrived and surrounded the activists.
A heavily armed officer asked to see the drone pilot’s Federal Aviation Administration license, which he provided. After confirming it was valid, a sheriff’s deputy — one of nine at the scene — told the activists they could remain on the road but could not trespass.
Asked about the heavy response, a deputy said there had been several recent violent incidents from animal rights groups at the site, and mentioned the groups had sent in “busloads” of activists.
The Times reached out to the Sheriff’s Office to get more details about those events but did not get a response.
Temple Grandin, author and professor of livestock medicine at Colorado State University, said that punching and kicking livestock is considered abusive.
An expert in livestock welfare, she said that handlers can tap, push and nudge animals. But if the level of force goes beyond what could bend the side of a cardboard box, “it’s abuse. Period.”
She said the calves’ reaction to the hot iron indicates that pain medication, such as lidocaine, was not applied before the procedure. Double D did not respond to a question about whether medication was given before the procedure.
