California case suggests Tamiflu may save cats infected with H5N1 bird flu

California case suggests Tamiflu may save cats infected with H5N1 bird flu

Since the avian flu arrived en force in California’s dairy industry in 2024, not only has it sickened cows, it has killed hundreds of domestic cats. Some pet cats that live on dairy farms were infected with the H5N1 virus by drinking raw milk. Both pets and feral barn cats got sick after eating raw pet food that harbored the virus. Still others got it by eating infected wild birds, rats or mice, or from contact with dairy workers’ contaminated clothes or boots.

But a new published case suggests that death may be averted if infected cats are treated early with antiviral medications, such as Tamiflu, or oseltamivir. Once treated, these animals may carry antibodies to the virus that makes them resistant to reinfection, at least temporarily.

The discovery was made by Jake Gomez, a veterinarian who treats small animals, such as cats and dogs, as well as large ones, including dairy cows, from his clinic, Cross Street Small Animal Veterinary Hospital, in Tulare.

Last fall, Gomez worked with a team of scientists from the University of Maryland and University of Texas who were in the Central Valley collecting blood samples from outdoor cats at dairy farms, looking to see if they could find antibodies to the H5N1 flu.

Cats are exquisitely sensitive to H5N1; one of the telltale signs that a dairy herd is infected is the presence of dead barn cats.

On Oct. 31, a cat owner brought in an indoor/outdoor cat to Gomez’ clinic that was ADR — a technical veterinarian acronym that stands for “ain’t doing right.”

The cat was up-to-date on all its vaccinations and the owner reported no known exposure to toxic chemicals.

Gomez offered to do blood work and urinalysis to probe more deeply what was going on, but the owner declined. So, Gomez sent them home with an antibiotic and an appetite stimulant. Two days later, the cat died.

It turned out the family had had another cat die just a few days earlier, Gomez said, recalling the visit.

Also during that time, Gomez was treating infected dairy herds around Tulare. Thousands of cows were falling sick from the virus. The family with the sick cats, he learned, lived less than a mile from an infected dairy, and the cat owner worked delivering hay to local dairies, spending time on infected farms.

“Considering how quickly it moved from one cat to the next, it occurred to me it might be H5N1,” he said.

Gomez said he reached out to the U.S. Department of Agriculture and the California Department of Food and Agriculture to see if they would test the dead animals for the virus. The agencies, he said, gave him the runaround and he couldn’t get anyone to answer his calls — which he said was perplexing, considering the rapid response when he alerted them to infected cattle.

“If I called to tell them a dairy herd had it, within 24 hours a SWAT team from the USDA and state would be swarming the farm,” he said. But for a cat? Crickets.

On Nov. 6 and 7, the family returned with two more sick cats.

Gomez said he still didn’t know what they had, but had a suspicion they could be infected with H5N1. So, he treated them with the antiviral oseltamivir, known also as Tamiflu, and they recovered.

In March this year, blood samples collected from the two cats showed high levels of antibodies to H5N1 — suggesting the cats had been exposed.

The case was published in the journal One Health.

Kristen Coleman, an airborne infectious disease researcher at the University of Maryland School of Public Health, and an author on the paper, said the findings suggest that cats may be effectively treated and that antiviral medications could help prevent further spread of the virus among cats living in the same home and the humans who care for them.

She said there have been no known transmissions from cats to humans in this outbreak, but there have in the past — in 2005, Thai zookeepers were infected by tigers that had the virus, and in 2016, New York veterinarians at an animal shelter got it from tending to sick cats.

But Jane Sykes, a professor of medicine and epidemiology at UC Davis School of Veterinary Medicine, said she’s not convinced the cats in this case actually had H5N1 — and urged people to read the study with care and caution.

“It’s possible that the positive antibody test results were unrelated to the reasons why those two cats died,” she said. “The virus wasn’t detected in any of the four cats, so infection was not proven.”

And whether the cats recovered because they were treated with Tamiflu, or whether the medication was incidental and they’d have recovered on their own — from another virus, infection or ailment — isn’t clear.

In addition, she said, no one has researched the effects of Tamiflu on cats. And while these two cats appeared to tolerate the drug, that doesn’t mean other cats will.

“Cats metabolize some of the anti-infective compounds very differently than other animals, including people, and they’re quite susceptible to bad side effects of many of these drugs,” she said. “We have to be really careful when we start just using random antiviral drugs that haven’t been studied for safety in cats, because they are so likely to get bad side effects.”

Having said that, she said if she were faced with a similar situation, a high certainty that a cat had been exposed, whether from drinking raw milk or eating raw food that had been infected, she would consider prescribing the medication. But she’d caution her client that it was experimental, and the animal could die from the drug.

She said there are numerous labs across the country that will test blood and urine for the virus.

Sykes urged people not to feed raw food or milk to their pets.

She said she’s seeing more raw food products for pets “and people want them, and they don’t understand the harms and the fact that some of these are contaminated for a long period of time with influenza viruses, like H5N1.”

Neither freezing nor smoking meat kills the virus.

“It’s astonishing how big this industry is getting,” Sykes said. “It’s crazy.”

Very little plastic being recycled in California as state efforts falter

Very little plastic being recycled in California as state efforts falter

California touts itself as a leader on the problem of plastic garbage, but recent developments suggest otherwise.

A new report issued by the state’s waste agency shows plastic yogurt containers, shampoo bottles and restaurant takeout trays are being recycled at rates only in the single digits.

Polypropylene, labeled as #5 on packaging, is used for yogurt containers, margarine tubs and microwavable trays. Only 2% of it is getting recycled. Colored shampoo and detergent bottles, made from polyethylene, or #1 plastic, are getting recycled at a rate of just 5%.

Other plastics, including ones promoted as highly recyclable, such as clear polyethylene bottles, which hold some medications, or hard water bottles, are being recycled at just 16%.

No plastic in the report exceeds a recycling rate of 23%, with the majority reported in just the single digits.

Adding to this disquieting assessment, CalRecycle also just pulled back regulations that were supposed to finalize a landmark single-use plastic law known as Senate Bill 54 — a law designed to make the majority of packaging waste in the state recyclable or compostable by working with the plastic and packaging industries.

The report and delay have sparked a wide variety of reactions by those who have closely watched the law as it was written and implemented.

The proposed regulations were regarded as friendly to industry. As a result, some are hopeful that CalRecycle’s decision to pull them back for tweaking means the agency will make the law stronger. Others say the two developments just show the state has never really been serious about plastic recycling.

“California’s SB 54 … will NEVER increase the recycling rates of these items … because cartons and plastic packaging are fundamentally not technically or economically recyclable,” said Jan Dell, the founder of Orange County-based Last Beach Cleanup, an anti-plastic organization.

Industry representatives are also expressing disappointment, saying the more delays and changes the state makes, the harder it is “for California businesses to comply with the law and implement the resulting changes,” said John Myers, a spokesman for the California Chamber of Commerce, which represents companies that will be affected.

Reports on abysmally low rates of recycling for milk cartons and polystyrene have been widely shared and known. But the newest numbers were still a grim confirmation that there are few options for dealing with these materials.

According to one state analysis, 2.9 million tons of single-use plastic and 171.4 billion single-use plastic components were sold, offered for sale or distributed in California in 2023.

Single-use plastics and plastic waste more broadly are considered a growing environmental and health problem. In recent decades, plastic waste has overwhelmed waterways and oceans, sickening marine life and threatening human health.

Last spring, the Newsom administration was accused of neutering the regulations that CalRecycle had initially proposed to implement the law. The changes excluded all packaging material related to produce, meat, dairy products, dog food, toothpaste, condoms, shampoo and cereal boxes, among other products. These are all products that might fall under the purview of the U.S. Food and Drug Administration and the U.S. Department of Agriculture.

It also opened the door to “alternative” recycling, such as chemical recycling, which environmentalists say is polluting, and was banned in the language of the law.

The waste agency then submitted those draft regulations to the Office of Administrative Law, whose lawyers and staff review proposed regulations to ensure they are “clear, necessary, legally valid, and available to the public” before finalizing them. They were set to release their determination on Friday; CalRecycle pulled the regulations back before the office issued its determination.

Neither the law office nor governor’s office responded to requests for comment.

Melanie Turner, CalRecycle’s spokeswoman, said the agency withdrew its proposed regulations “to make changes … to improve clarity and support successful implementation of the law,” and its revisions were focused on areas that dealt with “food and agricultural commodities.”

California State Sen. Ben Allen (D-Santa Monica), author of the original legislation, called the delay “entirely avoidable” in a statement, but said it would allow CalRecycle an “opportunity to ensure the regulations truly follow the law as it was signed.”

He urged the waste agency and Newsom’s administration not to “allow broad, sweeping exemptions that would undermine the program and increase costs for ratepayers.”

Critics of the watered-down regulations, such as Anja Brandon, the director of plastics policy for the Ocean Conservancy, said she wasn’t surprised by the withdrawal.

The proposed regulations “would have gone beyond CalRecycle’s authority by creating a sweeping categorical exclusion for food and agricultural packaging — effectively a loophole that would have allowed producers to continue putting vast amounts of plastic packaging into the marketplace, completely undermining SB 54’s goals and success,” she said in a text message.

Turner said CalRecycle will conduct a 15-day comment period — although when that begins has not yet been divulged.

Cancer survival rates soar nationwide, but L.A. doctors warn cultural and educational barriers leave some behind

Cancer survival rates soar nationwide, but L.A. doctors warn cultural and educational barriers leave some behind

The American Cancer Society’s 2026 Cancer Statistics report, released Tuesday, marks a major milestone for U.S. cancer survival rates. For the first time, the annual report shows that 70% of Americans diagnosed with cancer can expect to live at least five years, compared with just 49% in the mid-1970s.

The new findings, based on data from national cancer records and death statistics from 2015 to 2021, also show promising progress in survival rates for people with the deadliest, most advanced and hardest-to-treat cancers when compared with rates from the mid-1990s. The five-year survival rate for myeloma, for example, nearly doubled (from 32% to 62%). The survival rate for liver cancer tripled (from 7% to 22%), for late-stage lung cancer nearly doubled (from 20% to 37%), and for both melanoma and rectal cancer more than doubled (from 16% to 35% and from 8% to 18%, respectively).

For all cancers, the five-year survival rate more than doubled since the mid-1990s, rising from 17% to 35%.

This also signals a 34% drop in cancer mortality since 1991, translating to an estimated 4.8 million fewer cancer deaths between 1991 and 2023. These significant public health advances result from years of public investment in research, early detection and prevention, and improved cancer treatment, according to the report.

“This stunning victory is largely the result of decades of cancer research that provided clinicians with the tools to treat the disease more effectively, turning many cancers from a death sentence into a chronic disease,” said Rebecca Siegel, senior scientific director at the American Cancer Society and lead author of the report.

As more people survive cancer, there is also a growing focus on the quality of life after treatment. Patients, families and caregivers face physical, financial and emotional challenges. Dr. William Dahut, the American Cancer Society’s chief scientific officer, said that ongoing innovation must go hand in hand with better support services and policies, so all survivors — not just the privileged — can have “not only more days, but better days.”

Indeed, the report also shows that not everyone has benefited equally from the advances of the last few decades. American Indian and Alaska Native people now have the highest cancer death rates in the country, with deaths from kidney, liver, stomach and cervical cancers about double that of white Americans.

Additionally, Black women are more likely to die from breast and uterine cancers than non-Black women — and Black men have the highest cancer rates of any American demographic. The report connects these disparities in survival to long-standing issues such as income inequity and the effects of past discrimination, such as redlining, affecting where people live — forcing historically marginalized populations to be disproportionately exposed to environmental carcinogens.

Dr. René Javier Sotelo, a urologic oncologist at Keck Medicine of USC, notes that the fight against cancer in Southern California, amid long-standing disparities facing vulnerable communities, is very much about overcoming educational, cultural and socioeconomic barriers.

While access to care and insurance options in Los Angeles are relatively robust, many disparities persist because community members often lack crucial information about risk factors, screening and early warning signs. “We need to insist on the importance of education and screening,” Sotelo said. He emphasized that making resources, helplines and culturally tailored materials readily available to everyone is crucial.

He cites penile cancer as a stark example: rates are higher among Latino men in L.A., not necessarily due to lack of access, but because of gaps in awareness and education around HPV vaccination and hygiene.

Despite these persisting inequities, the dramatic nationwide improvement in cancer survival is unquestionably good news, bringing renewed hope to many individuals and families. However, the report also gives a clear warning: Proposed federal cuts to cancer research and health insurance could stop or even undo these important gains.

“We can’t stop now,” warned Shane Jacobson, the American Cancer Society’s chief executive.

“We need to understand that we are not yet there,” Sotelo concurred. ”Cancer is still an issue.”

Clashing with the state, L.A. City moves to adopt lenient wildfire ‘Zone Zero’ regulations

Clashing with the state, L.A. City moves to adopt lenient wildfire ‘Zone Zero’ regulations

As the state continues multiyear marathon discussions on rules for what residents in wildfire hazard zones must do to make the first five feet from their houses — an area dubbed “Zone Zero” — ember-resistant, the Los Angeles City Council voted Tuesday to start creating its own version of the regulations that is more lenient than most proposals currently favored in Sacramento.

Critics of Zone Zero, who are worried about the financial burden and labor required to comply as well as the detrimental impacts to urban ecosystems, have been particularly vocal in Los Angeles. However, wildfire safety advocates worry the measures endorsed by L.A.’s City Council will do little to prevent homes from burning.

“My motion is to get advice from local experts, from the Fire Department, to actually put something in place that makes sense, that’s rooted in science,” said City Councilmember John Lee, who put forth the motion. “Sacramento, unfortunately, doesn’t consult with the largest city in the state — the largest area that deals with wildfires — and so, this is our way of sending a message.”

Tony Andersen — executive officer of the state’s Board of Forestry and Fire Protection, which is in charge of creating the regulations — has repeatedly stressed the board’s commitment to incorporating L.A.’s feedback. Over the last year, the board hosted a contentious public meeting in Pasadena, walking tours with L.A. residents and numerous virtual workshops and hearings.

Some L.A. residents are championing a proposed fire-safety rule, referred to as “Zone Zero,” requiring the clearance of flammable material within the first five feet of homes. Others are skeptical of its value.

With the state long past its original Jan. 1, 2023, deadline to complete the regulations, several cities around the state have taken the matter into their own hands and adopted regulations ahead of the state, including Berkeley and San Diego.

“With the lack of guidance from the State Board of Forestry and Fire Protection, the City is left in a precarious position as it strives to protect residents, property, and the landscape that creates the City of Los Angeles,” the L.A. City Council motion states.

However, unlike San Diego and Berkeley, whose regulations more or less match the strictest options the state Board of Forestry is considering, Los Angeles is pushing for a more lenient approach.

The statewide regulations, once adopted, are expected to override any local versions that are significantly more lenient.

The Zone Zero regulations apply only to rural areas where the California Department of Forestry and Fire Protection responds to fires and urban areas that Cal Fire has determined have “very high” fire hazard. In L.A., that includes significant portions of Silver Lake, Echo Park, Brentwood and Pacific Palisades.

Fire experts and L.A. residents are generally fine with many of the measures within the state’s Zone Zero draft regulations, such as the requirement that there be no wooden or combustible fences or outbuildings within the first five feet of a home. Then there are some measures already required under previous wildfire regulations — such as removing dead vegetation like twigs and leaves, from the ground, roof and gutters — that are not under debate.

However, other new measures introduced by the state have generated controversy, especially in Los Angeles. The disputes have mainly centered around what to do about trees and other living vegetation, like shrubs and grass.

The state is considering two options for trees: One would require residents to trim branches within five feet of a house’s walls and roof; the other does not. Both require keeping trees well-maintained and at least 10 feet from chimneys.

On vegetation, the state is considering options for Zone Zero ranging from banning virtually all vegetation beyond small potted plants to just maintaining the regulations already on the books, which allow nearly all healthy vegetation.

Lee’s motion instructs the Los Angeles Fire Department to create regulations in line with the most lenient options that allow healthy vegetation and do not require the removal of tree limbs within five feet of a house. It is unclear whether LAFD will complete the process before the Board of Forestry considers finalized statewide regulations, which it expects to do midyear.

The motion follows a pointed report from LAFD and the city’s Community Forest Advisory Committee that argued the Board of Forestry’s draft regulations stepped beyond the intentions of the 2020 law creating Zone Zero, would undermine the city’s biodiversity goals and could result in the loss of up to 18% of the urban tree canopy in some neighborhoods.

The board has not decided which approach it will adopt statewide, but fire safety advocates worry that the lenient options championed by L.A. do little to protect vulnerable homes from wildfire.

Recent studies into fire mechanics have generally found that the intense heat from wildfire can quickly dry out these plants, making them susceptible to ignition from embers, flames and radiant heat. And anything next to a house that can burn risks taking the house with it.

Another recent study that looked at five major wildfires in California from the last decade, not including the 2025 Eaton and Palisades fires, found that 20% of homes with significant vegetation in Zone Zero survived, compared to 37% of homes that had cleared the vegetation.
