With bird flu cases on the rise, staff at California lab say they are overworked and burned out
On a recent Friday morning, Alyssa Laxamana arrived at a laboratory on the UC Davis campus to continue California’s race against bird flu.
A note from her supervisor had alerted Laxamana that about 130 samples of cow milk and other dairy products were en route — a large but manageable workload. She got to work preparing the buffer solutions and other supplies she would need to test the samples for H5N1 influenza, the virus that causes the flu spreading through California’s cattle and poultry farms.
Laxamana’s plans, however, quickly went out the window. More samples kept popping up in a digital queue as another lab worker logged unexpected shipments. Around noon she had to draw a line. She calculated she could get through about 270 samples that day. The rest would have to wait.
“I can only do so much,” Laxamana recalled saying to herself.
Laxamana works in the biotechnology department of the California Animal Health and Food Safety Laboratory, the first line of defense in the state’s effort to track and prevent the spread of the H5N1 virus.
Far from working at full capacity, however, the Davis lab has been roiled over the past year by workplace tensions. Understaffing and poor management, Laxamana and other current and former employees say, have left lab employees overworked and struggling to keep pace with testing demands, while creating an environment where mistakes are more likely. An exodus of most of the staff this year left Laxamana and a co-worker for a period as the only two people testing for the virus on a daily basis.
The stakes for the lab are high: It is the only lab in the state with the authority to confirm bird flu cases. Although there is no evidence that the alleged workplace problems have contributed to an outbreak, processing tests quickly gives farmers a jump on quarantining or culling infected animals.
“Any potential delay in testing could result in greater spread,” said Richard Webby, a virologist at St. Jude Children’s Research Hospital in Tennessee, who specializes in influenza in birds and other animals.
The problems come amid a rising tide of bird flu cases at poultry and dairy farms and an increasing threat to humans. Last week the Davis lab confirmed the virus had been found in a retail sample of raw milk from a Fresno-based dairy, which health officials warn may have been sold in stores in Los Angeles County. And, so far, about 30 people in the state — the vast majority of them dairy workers — are known to have been infected.
Bill Kisliuk, a spokesperson for UC Davis, denied that workplace issues have left the lab ill-equipped to handle bird flu testing. He said the facility has “maintained the supervision, staffing and resources necessary to provide timely and vital health and safety information to those asking us to perform tests throughout the current outbreak of avian flu.”
After The Times inquired about staffing levels and other workplace issues, the Governor’s Office of Emergency Services inspected the lab in October, while UC Davis officials hired more staff and got help from a lab in Wisconsin, according to current staff. UC Davis officials declined to confirm the moves.
The spokesperson for the California Department of Food and Agriculture, which jointly operates the lab, deferred questions to UC Davis, saying, “CAHFS lab has done tremendous work under demanding circumstances.”
The virus is taking a rising toll on the state’s dairy and poultry industries. Since September, outbreaks at turkey farms, chicken broilers, egg-laying facilities and other producers around the state have affected more than 6 million birds, according to USDA data. And while the virus is less lethal in cows than birds, dead cows and calves have piled up along roadsides in Tulare County, with farmers and veterinarians reporting mortality rates far higher than expected. Also worrisome for a state that produces 20% of the country’s milk is the steep drop-off in milk production farmers have reported among cows that recover from the flu.
Discontent over staffing, pay and other alleged workplace issues has pervaded the lab over the past two years, emails and other communications reviewed by The Times show.
In May 2023, employees in the biotechnology section sent a petition to the lab’s managers demanding they address the staff’s concerns. After getting no reply, they sent another note viewed by The Times in November, accusing managers of refusing “time and again” to make improvements. Their workload, they added, had “measurably increased” since the temporary closure of the another CAHFS lab in Tulare earlier that year due to flooding.

“We operate with the mindset that the next outbreak is always around the corner, and we need proper training opportunities and competitive salary to remain adequately staffed for that eventuality,” they wrote.
Several lab staff quit their jobs in the first half of 2024, leaving behind what they described as a relatively inexperienced, skeletal crew.
Helen Kado-Fong, a supervisor who had worked in the biotechnology department for about 12 years decided to retire early in May. She said she had become fed up with what she described as an attitude of indifference or hostility toward efforts by her and others in the lab to raise concerns.
In an email she sent a few months before she left to the dean of UC Davis veterinary school and CAHFS director, Kado-Fong warned the “high turnover and disengagement of technical staff is weakening the ability of the CAHFS laboratory to fulfill its mission.”
Another to quit was Kayla Dollar, a lab assistant in the department for about two years, who said she left in June after being rejected for a promotion to a lab technician. Dollar said she was told she didn’t get the job because she didn’t have sufficient experience. Dollar said she was perplexed by the explanation because her supervisor Kado-Fong had been trying to get the OK to have Dollar receive training to prepare her for the technician role.
“I was hitting a wall at every turn,” Dollar said.
Dollar was hired at a UC Davis veterinary genetics lab in June as a biotechnologist, the same position she had been rejected from at CAHFS.
And Jasmine Burke quit her post as one of the lab’s technicians in July, she said, after being threatened with discipline for raising concerns about long work hours and rushed testing procedures. She and others said that as the lab rushed to meet 24-hour turnaround times for bird flu testing, other types of tests became backlogged, and she and other staff failed at times to keep up with routine lab maintenance, such as recalibrating machines and ensuring refrigerators holding samples and chemical solutions were set at the correct temperature.
“Every attempt to communicate concerns here goes nowhere,” she wrote to the university’s human resources department, according to an email viewed by The Times. Burke now works as a barista at a coffee shop.
Kisliuk, the UC Davis spokesperson, declined to respond to questions about specific incidents involving employees. “When a staff member reports concerns about workplace safety or conditions, we review the matter and take the appropriate steps,” he wrote in an emailed statement.
By July, five employees had departed, leaving behind only Laxamana and colleague Victoria Ontiveros, who have worked in the lab for two years or less.
Late one afternoon on a day in September, Ontiveros recalled how she changed into scrubs and donned two sets of surgical gloves, goggles, an N95 mask, a lab coat and a hairnet — the required gear for entering the Biosafety Level 3 lab, or BSL-3, where samples suspected of containing the virus are tested. Only approved staff can enter the facility through a locked door that requires an iris scan to open.

Ontiveros had already done several long shifts in the BSL-3 that week, which with normal staffing would have been divided among multiple people, she said. Now, she was preparing to test cow milk samples that had arrived at the lab around 2 p.m. Typically, samples received after noon were tested the following day, but she said her supervisors had insisted these needed to be turned around quickly as infections spread.
She said she worked for hours, painstakingly pipetting drops of the samples into tiny glass wells as part of the testing process, which extracts genetic material in order to detect the presence of the virus. Then, late in the evening, she realized she had programmed one of the machines analyzing the samples incorrectly. Ontiveros felt a sharp pang of despair. All her work, and the hours Laxamana had spent earlier in the day mixing a chemical solution to wash the samples, had been wasted.
It was around 9 p.m. when she emerged from the lab. She had started her workday around 8 a.m. The tests would have to be redone the next day.
“We are stretched so thin that mistakes can happen,” Ontiveros said. “I was so tired and mentally drained.”
At the time, Ontiveros said she was handling the testing of cow milk largely on her own, although another worker was sometimes sent up from the Tulare lab to help on weekends. While Laxamana had the required security clearance, she hadn’t yet completed the necessary training.
“There’s this huge pressure on me and and responsibility to show up to work every day because I have no backup,” Ontiveros said.
Later in September, Laxamana described being put straight to work as the number of cattle milk samples was ramping up. She said she was asked to run 44 samples without ever having completed a practice run. The only hands-on training she had had was twice shadowing the testing process. As Laxamana worked, Ontiveros stood nearby, supervising.
Already nervous, Laxamana said she was distracted by a walkie-talkie that crackled with voices as she tried to work. Colleagues in the main lab were peppering her with questions about what to do about another batch of tests that appeared to have failed. Holding a pipette carefully in one hand, Laxamana talked through the radio to troubleshoot the problem.
At times this year understaffing has led to quality control missteps, current and former workers said.
Laxamana described coming to work one morning in October and realizing results of tests she had run the day before had not been analyzed properly by lab staff. She said a manager assured Laxamana the errors would be corrected, but when she checked later that day the results had not been changed.
She said she stopped a case coordinator from releasing the incorrect results to farmers, which would have resulted in the culling of birds.
Earlier this year, a poultry sample got misplaced and went untested for three weeks, Laxamana said. She attributed the mistake to being overworked, saying, “There were only two people handling the workload, and things were missed in all of that chaos.”
Kisliuk, the UC Davis spokesperson, declined to answer questions about specific incidents described where workers made mistakes or where managers made mistakes. “We have multiple levels of quality assurance and extensive training of staff,” he said.
In late summer the lab hired a supervisor and others to join the lab. The move created additional work for Laxamana and Ontiveros, who said they were required to juggle their own work while also helping with training the new arrivals.
In recent weeks the supervisor and another new hire took over testing of high-risk poultry samples, but Laxamana and Ontiveros said staffing shortages remain.
Still, Laxamana doesn’t think about leaving.
“There are things that I can do to help prevent a disaster,” she said.“I could not bear to leave the lab in the condition that it is right now.”

How our AI bots are ignoring their programming and giving hackers superpowers
Welcome to the age of AI hacking, in which the right prompts make amateurs into master hackers.
A group of cybercriminals recently used off-the-shelf artificial intelligence chatbots to steal data on nearly 200 million taxpayers. The bots provided the code and ready-to-execute plans to bypass firewalls.
Although they were explicitly programmed to refuse to help hackers, the bots were duped into abetting the cybercrime.
According to a recent report from Israeli cybersecurity firm Gambit Security, hackers last month used Claude, the chatbot from Anthropic, to steal 150 gigabytes of data from Mexican government agencies.
Claude initially refused to cooperate with the hacking attempts and even denied requests to cover the hackers’ digital tracks, the experts who discovered the breach said. The group pummelled the bot with more than 1,000 prompts to bypass the safeguards and convince Claude they were allowed to test the system for vulnerabilities.
AI companies have been trying to create unbreakable chains on their AI models to restrain them from helping do things such as generating child sexual content or aiding in sourcing and creating weapons. They hire entire teams to try to break their own chatbots before someone else does.
But in this case, hackers continuously prompted Claude in creative ways and were able to “jailbreak” the chatbot to assist them. When they encountered problems with Claude, the hackers used OpenAI’s ChatGPT for data analysis and to learn which credentials were required to move through the system undetected.
The group used AI to find and exploit vulnerabilities, bypass defences, create backdoors and analyze data along the way to gain control of the systems before they stole 195 million identities from nine Mexican government systems, including tax records, vehicle registration as well as birth and property details.
AI “doesn’t sleep,” Curtis Simpson, chief executive of Gambit Security, said in a blog post. “It collapses the cost of sophistication to near zero.”
“No amount of prevention investment would have made this attack impossible,” he said.
Anthropic did not respond to a request for comment. It told Bloomberg that it had banned the accounts involved and disrupted their activity after an investigation.
OpenAI said it is aware of the attack campaign carried out using Anthropic’s models against the Mexican government agencies.
“We also identified other attempts by the adversary to use our models for activities that violate our usage policies; our models refused to comply with these attempts,” an OpenAI spokesperson said in a statement. “We have banned the accounts used by this adversary and value the outreach from Gambit Security.”
Instances of generative AI-assisted hacking are on the rise, and the threat of cyberattacks from bots acting on their own is no longer science fiction. With AI doing their bidding, novices can cause damage in moments, while experienced hackers can launch many more sophisticated attacks with much less effort.
Earlier this year, Amazon discovered that a low-skilled hacker used commercially available AI to breach 600 firewalls. Another took control of thousands of DJI robot vacuums with help from Claude, and was able to access live video feed, audio and floor plans of strangers.
“The kinds of things we’re seeing today are only the early signs of the kinds of things that AIs will be able to do in a few years,” said Nikola Jurkovic, an expert working on reducing risks from advanced AI. “So we need to urgently prepare.”
Late last year, Anthropic warned that society has reached an “inflection point” in AI use in cybersecurity after disrupting what the company said was a Chinese state-sponsored espionage campaign that used Claude to infiltrate 30 global targets, including financial institutions and government agencies.
Generative AI also has been used to extort companies, create realistic online profiles by North Korean operatives to secure jobs in U.S. Fortune 500 companies, run romance scams and operate a network of Russian propaganda accounts.
Over the last few years, AI models have gone from being able to manage tasks lasting only a few seconds to today’s AI agents working autonomously for many hours. AI’s capability to complete long tasks is doubling every seven months.
“We just don’t actually know what is the upper limit of AI’s capability, because no one’s made benchmarks that are difficult enough so the AI can’t do them,” said Jurkovic, who works at METR, a nonprofit that measures AI system capabilities to cause catastrophic harm to society.
So far, the most common use of AI for hacking has been social engineering. Large language models are used to write convincing emails to dupe people out of their money, causing an eight-fold increase in complaints from older Americans as they lost $4.9 billion in online fraud in 2025.
“The messages used to elicit a click from the target can now be generated on a per-user basis more efficiently and with fewer tell-tale signs of phishing,” such as grammatical and spelling errors, said Cliff Neuman, an associate professor of computer science at USC.
AI companies have been responding using AI to detect attacks, audit code and patch vulnerabilities.
“Ultimately, the big imbalance stems from the need of the good-actors to be secure all the time, and of the bad-actors to be right only once,” Neuman said.
The stakes around AI are rising as it infiltrates every aspect of the economy. Many are concerned that there is insufficient understanding of how to ensure it cannot be misused by bad actors or nudged to go rogue.
Even those at the top of the industry have warned users about the potential misuse of AI.
Dario Amodei, the CEO of Anthropic, has long advocated that the AI systems being built are unpredictable and difficult to control. These AIs have shown behaviors as varied as deception and blackmail, to scheming and cheating by hacking software.
Still, major AI companies — OpenAI, Anthropic, xAI, and Google — signed contracts with the U.S. government to use their AIs in military operations.
This last week, the Pentagon directed federal agencies to phase out Claude after the company refused to back down on its demand that it wouldn’t allow its AI to be used for mass domestic surveillance and fully autonomous weapons.
“The AI systems of today are nowhere near reliable enough to make fully autonomous weapons,” Amodei told CBS News.

iPic movie theater chain files for bankruptcy
The iPic dine-in movie theater chain has filed for Chapter 11 bankruptcy protection and intends to pursue a sale of its assets, citing the difficult post-pandemic theatrical market.
The Boca Raton, Fla.-based company has 13 locations across the U.S., including in Pasadena and Westwood, according to a Feb. 25 filing in U.S. Bankruptcy Court in the Southern District of Florida, West Palm Beach division.
As part of the bankruptcy process, the Pasadena and Westwood theaters will be permanently closed, according to WARN Act notices filed with the state of California’s Employment Development Department.
The company came to its conclusion after “exploring a range of possible alternatives,” iPic Chief Executive Patrick Quinn said in a statement.
“We are committed to continuing our business operations with minimal impact throughout the process and will endeavor to serve our customers with the high standard of care they have come to expect from us,” he said.
The company will keep its current management to maintain day-to-day operations while it goes through the bankruptcy process, iPic said in the statement. The last day of employment for workers in its Pasadena and Westwood locations is April 28, according to a state WARN Act notice. The chain has 1,300 full- and part-time employees, with 193 workers in California.
The theatrical business, including the exhibition industry, still has not recovered from the pandemic’s effect on consumer behavior. Last year, overall box office revenue in the U.S. and Canada totaled about $8.8 billion, up just 1.6% compared with 2024. Even more troubling is that industry revenue in 2025 was down 22.1% compared with pre-pandemic 2019’s totals.
IPic noted those trends in its bankruptcy filing, describing the changes in consumer behavior as “lasting” and blaming the rise of streaming for “fundamentally” altering the movie theater business.
“These industry shifts have directly reduced box office revenues and related ancillary revenues, including food and beverage sales,” the company stated in its bankruptcy filing.
IPic also attributed its decision to rising rents and labor costs.
The company estimated it owed about $141,000 in taxes and about $2.7 million in total unsecured claims. The company’s assets were valued at about $155.3 million, the majority of which coming from theater equipment and furniture. Its liabilities totaled $113.9 million.
The chain had previously filed for bankruptcy protection in 2019.

Startup Varda Space Industries snags former Mattel plant in El Segundo
In an expansion of its business of processing pharmaceuticals in Earth’s orbit, Varda Space Industries is renting a large El Segundo plant where toy manufacturer Mattel used to design Hot Wheels and Barbie dolls.
The plant in El Segundo’s aerospace corridor will be an extension of Varda Space Industries’ headquarters in a much smaller building on nearby Aviation Boulevard.
Varda will occupy a 205,443-square-foot industrial and office campus at 2031 E. Mariposa Ave., which will give it additional capacity to manufacture spacecraft at scale, the company said.
Originally built in the 1940s as an aircraft facility, the complex has a history as part of aerospace and defense industries that have long shaped the South Bay and is near a host of major defense and space contractors. It is also close to Los Angeles Air Force Base, headquarters to the Space Systems Command.
Workers test AstroForge’s Odin asteroid probe, which was lost in space after launch this year.

Varda is one of a new generation of aerospace startups that have flourished in Southern California and the South Bay over the last several years, particularly in El Segundo, often with ties to SpaceX.
Elon Musk’s company, founded in 2002 in El Segundo, has revolutionized the industry with reusable rockets that have radically lowered the cost of lifting payloads into space. Though it has moved its headquarters to Texas, SpaceX retains large-scale operations in Hawthorne.
Varda co-founder and Chief Executive Will Bruey is a former SpaceX avionics engineer, and the company’s spacecraft are launched on SpaceX’s workhorse Falcon 9 rockets from Vandenberg Space Force Base in Santa Barbara County.
Varda makes automated labs that look like cylindrical desktop speakers, which it sends into orbit in capsules and satellite platforms it also builds. There, in microgravity, the miniature labs grow molecular crystals that are purer than those produced in Earth’s gravity for use in pharmaceuticals.
It has contracts with drug companies and also the military, which tests technology at hypersonic speeds as the capsules return to Earth.
Its fifth capsule was launched in November and returned to Earth in late January; its next mission is set in the coming weeks. Varda has more than 10 missions scheduled on Falcon 9s through 2028.
For the last several decades, the Mariposa Avenue property served as the research and development center for Mattel Toys. El Segundo has also long been a center for the toy industry as companies like to set up shop in the shadow of Mattel.
The Mattel facility “has always been an exceptional property with a legacy tied to aerospace innovation, and leasing to Varda Space Industries feels like a natural continuation of that story,” said Michael Woods, a partner at GPI Cos., which owns the property.
“We are proud to support a company that is genuinely pushing the boundaries of what’s possible, and are excited to watch Varda grow and thrive here in El Segundo,” Woods said.
As one of the country’s most active hubs of aerospace and defense innovation, El Segundo has seen its industrial property vacancy fall to 3.4% on demand from space companies, government contractors and technology startups, real estate brokerage CBRE said.
Successful startups often have to leave the neighborhood when they want to expand, real estate broker Bob Haley of CBRE said. The 9-acre Mattel facility was big enough to keep Varda in the city.
Last year, Varda subleased about 55,000 square feet of lab space from alternative protein company Beyond Meat at 888 Douglas St. in El Segundo, which it started moving into in June.
Varda will get the keys to its new building in December and spend four to eight months building production and assembly facilities as it ramps up operations. By the end of next year, it expects to have constructed 10 more spacecraft.
In the future, Varda could consolidate offices there, given its size. Currently, though, the plan is to retain all properties, creating a campus of three buildings within a mile of one another that are served by the company’s transportation services, Chief Operating Officer Jonathan Barr said.
“We already have Varda-branded shuttles running up and down Aviation Boulevard,” he said.
