Dozens of packaged foods recalled in listeria outbreak. Here's what you need to know
After federal inspectors found potentially deadly bacteria in samples of its products, Modesto-based Rizo Lopez Foods Inc. recalled all of its packaged goods this month, including various types of cotija cheese, yogurt and sour cream.
The bacterium in question, Listeria monocytogenes, can cause listeriosis, a foodborne infection that is often innocuous but occasionally lethal. According to the U.S. Food and Drug Administration, one particular genetic strain of the bacterium has been tied to infections dating back to June 2014.
The agency investigated the string of infections in 2017 and 2021 and found a probable link to queso fresco and similar cheeses, but it couldn’t tell which company or companies had sold the products. Then in January, health officials found the same strain of listeria in a sample of Rizo Bros Aged Cotija. Tests by the FDA at Rizo Lopez Foods’ manufacturing plant also found a sample with that strain, prompting the company to voluntarily recall its entire product line.
Since then, numerous manufacturers of packaged foods that contained Rizo Bros cheeses have recalled their products. These include salads and prepared meals from Dole, Trader Joe’s, Von’s, Costco, Albertsons and Bristol Farms.
Only 26 infections linked to this strain have been reported to the U.S. Centers for Disease Control and Prevention, but the CDC says that many people who contract listeria don’t report it. The agency interviewed 22 of the people infected, and 16 said they’d eaten queso fresco, cotija or similar cheeses.
Considering the number of products that Rizo Lopez has sold and the small number of reported cases, the odds of someone falling dangerously ill seem slim. Nevertheless, the FDA recommends that people check their refrigerators and freezers for recalled products and throw away any they find.
Here’s what you need to know about the disease and the recent recalls.
What is listeria?
Technically, the term refers to the bacteria, but it often is used instead to refer to listeriosis, the illness. Unusually hardy, the bacteria can survive refrigeration and even freezing, the Mayo Clinic says.
Potential breeding grounds for the bacteria are moist environments, soil, water, decaying vegetation and animals, the FDA says. Food can pick up the bacteria by coming into contact with contaminated surfaces or environments; pets who eat contaminated foods can also spread it through the home.
What are the symptoms of a listeria infection?
According to the Mayo Clinic, “healthy people rarely become ill from listeria infection.” If you do feel symptoms, they may start like a stomach bug, with vomiting and diarrhea beginning up to 24 hours after eating contaminated food and lasting one to three days. But this kind of illness is rarely diagnosed, the CDC says, because laboratories do not usually look for listeria when testing patients’ stool samples.
The threat is that the infection will spread beyond the stomach, becoming invasive.
According to the CDC, for those who are pregnant, the symptoms of invasive listeriosis are usually like the flu — fever, muscle aches and fatigue — but tend to be mild, if they appear at all. But the risk to a fetus is dire; infection during pregnancy “usually leads to miscarriage, stillbirth, premature delivery, or life-threatening infection of the newborn,” the CDC says.
For those who aren’t pregnant, the symptoms can be serious. They include fever, headache, muscle aches, stiff neck, confusion, loss of balance and seizures. Almost 5% of the non-pregnant people who come down with invasive listeriosis die, according to the CDC.
Who is most at risk?
Because of the danger to fetuses and newborns, pregnant women are a prime risk group. But so are people with weaker immune systems, because of either their age or a medical condition or treatment regimen that lowers their body’s natural defenses.
The CDC warns that people 65 and older are four times more likely to contract listeriosis than others are. People with cancer are 10 times more likely, and people who need dialysis are 50 times more susceptible.
How is listeria transmitted?
It’s a foodborne disease, which means you get it from eating something contaminated with the bacteria. And those are found most often in unpasteurized dairy products and improperly processed meats, the Mayo Clinic says.
How can you avoid getting infected?
First and foremost, the CDC advises not to eat any of the dairy products manufactured by Rizo Lopez Foods or its customers. In other words, check the recall list (see below, but also check for updates at the FDA’s listeria outbreak web page) and don’t consume those products.
If you had any of those products in your refrigerator or freezer, you should sanitize any surfaces or containers that they touched, following the FDA’s guidelines for safe handling and cleaning. Otherwise, the hardy listeria bacteria will troop across surfaces to contaminate other products.
Where have listeria infections been reported?
The 26 cases tracked by the CDC are primarily spread across the southern and western United States. The largest number of cases — 8, or 30% of the total — have been in California. Arizona and Colorado have each seen four cases, Texas and Tennessee each have two reported cases, and six other states each have one.
Which products have been recalled?
Rizo Lopez has recalled nearly 60 products, most of which are Mexican cheeses and cremas under the brand names Tio Francisco, Rizo Bros, Casa Cardenas and Campesino.
In addition, the Rizo Lopez recalled product line includes:
- Cotija cheese, 16-ounce packages by Food City
- Cotija Enchilado cheese, 16-ounce packages by Food City
- Crema Mexicana, 16-ounce packages by Food City and Santa Maria, and at retail deli counters by San Carlos
- Fresco cheese at deli counters by San Carlos, El Huache and La Ordena
- Oaxaca cheese, 16-ounce packages by Food City, and at retail deli counters by San Carlos
- Panela cheese, 16-ounce packages by Food City, and at retail deli counters by San Carlos, Dos Ranchitos and La Ordena
- Queso Crema, 16-ounce packages by Food City, and at retail deli counters by San Carlos
- Queso Fresco, 10- and 12-ounce packages by Don Francisco, 14-ounce packages by Rio Grande, 16-ounce packages by Food City, and at retail deli counters by San Carlos, Santa Maria and Dos Ranchitos
- Ricotta cheese, part skim and whole milk varieties, 15-ounce packages by 365 by Whole Foods Market
But wait, there’s more. The FDA on Wednesday released a list of 16 recalled processed food items made in part with dairy products from Rizo Lopez. The brands on the list were Bright Farms, Campesino, Casa Cardenas, Dole, Don Francisco, Don Pancho, Dos Ranchitos, El Huache, Food City, Fresh & Ready Foods, Fresh Express, H-E-B, Jack & Olive, La Ordena, Marketside, Maverick Foods, President’s Choice, Ready Pac Bistro, Rio Grande, Rizo Bros, Rojo’s, San Carlos, Santa Maria, Sprig & Sprout, the Perfect Bite Co., Tio Francisco, Trader Joe’s, and 365 by Whole Foods Market. Some of the 16 items were sold by multiple brands.
Some supermarkets also sold unbranded taco kits, wraps and meals that included recalled Rizo Lopez cheeses. These were Albertsons, Bristol Farms, Carrs-Safeway, Costco, Eagle, Lucky, Pavilions, Randalls, Safeway, Save Mart, Shaw’s, Sprouts, Star Market, Stater Bros. Markets, Tom Thumb and Vons.

U.S. Space Force awards $1.6 billion in contracts to South Bay satellite builders
The U.S. Space Force announced Friday it has awarded satellite contracts with a combined value of about $1.6 billion to Rocket Lab in Long Beach and to the Redondo Beach Space Park campus of Northrop Grumman.
The contracts by the Space Development Agency will fund the construction by each company of 18 satellites for a network in development that will provide warning of advanced threats such as hypersonic missiles.
Northrop Grumman has been awarded contracts for prior phases of the Proliferated Warfighter Space Architecture, a planned network of missile defense and communications satellites in low Earth orbit.
The contract announced Friday is valued at $764 million, and the company is now set to deliver a total of 150 satellites for the network.
The $805-million contract awarded to Rocket Lab is its largest to date. It had previously been awarded a $515 million contract to deliver 18 communications satellites for the network.
Founded in 2006 in New Zealand, the company builds satellites and provides small-satellite launch services for commercial and government customers with its Electron rocket. It moved to Long Beach in 2020 from Huntington Beach and is developing a larger rocket.
“This is more than just a contract. It’s a resounding affirmation of our evolution from simply a trusted launch provider to a leading vertically integrated space prime contractor,” said Rocket Labs founder and chief executive Peter Beck in online remarks.
The company said it could eventually earn up to $1 billion due to the contract by supplying components to other builders of the satellite network.
Also awarded contracts announced Friday were a Lockheed Martin group in Sunnyvalle, Calif., and L3Harris Technologies of Fort Wayne, Ind. Those contracts for 36 satellites were valued at nearly $2 billion.
Gurpartap “GP” Sandhoo, acting director of the Space Development Agency, said the contracts awarded “will achieve near-continuous global coverage for missile warning and tracking” in addition to other capabilities.
Northrop Grumman said the missiles are being built to respond to the rise of hypersonic missiles, which maneuver in flight and require infrared tracking and speedy data transmission to protect U.S. troops.
Beck said that the contracts reflects Rocket Labs growth into an “industry disruptor” and growing space prime contractor.

California-based company recalls thousands of cases of salad dressing over ‘foreign objects’
A California food manufacturer is recalling thousands of cases of salad dressing distributed to major retailers over potential contamination from “foreign objects.”
The company, Irvine-based Ventura Foods, recalled 3,556 cases of the dressing that could be contaminated by “black plastic planting material” in the granulated onion used, according to an alert issued by the U.S. Food and Drug Administration.
Ventura Foods voluntarily initiated the recall of the product, which was sold at Costco, Publix and several other retailers across 27 states, according to the FDA.
None of the 42 locations where the product was sold were in California.
Ventura Foods said it issued the recall after one of its ingredient suppliers recalled a batch of onion granules that the company had used n some of its dressings.
“Upon receiving notice of the supplier’s recall, we acted with urgency to remove all potentially impacted product from the marketplace. This includes urging our customers, their distributors and retailers to review their inventory, segregate and stop the further sale and distribution of any products subject to the recall,” said company spokesperson Eniko Bolivar-Murphy in an emailed statement. “The safety of our products is and will always be our top priority.”
The FDA issued its initial recall alert in early November. Costco also alerted customers at that time, noting that customers could return the products to stores for a full refund. The affected products had sell-by dates between Oct. 17 and Nov. 9.
The company recalled the following types of salad dressing:
- Creamy Poblano Avocado Ranch Dressing and Dip
- Ventura Caesar Dressing
- Pepper Mill Regal Caesar Dressing
- Pepper Mill Creamy Caesar Dressing
- Caesar Dressing served at Costco Service Deli
- Caesar Dressing served at Costco Food Court
- Hidden Valley, Buttermilk Ranch

They graduated from Stanford. Due to AI, they can’t find a job
A Stanford software engineering degree used to be a golden ticket. Artificial intelligence has devalued it to bronze, recent graduates say.
The elite students are shocked by the lack of job offers as they finish studies at what is often ranked as the top university in America.
When they were freshmen, ChatGPT hadn’t yet been released upon the world. Today, AI can code better than most humans.
Top tech companies just don’t need as many fresh graduates.
“Stanford computer science graduates are struggling to find entry-level jobs” with the most prominent tech brands, said Jan Liphardt, associate professor of bioengineering at Stanford University. “I think that’s crazy.”
While the rapidly advancing coding capabilities of generative AI have made experienced engineers more productive, they have also hobbled the job prospects of early-career software engineers.
Stanford students describe a suddenly skewed job market, where just a small slice of graduates — those considered “cracked engineers” who already have thick resumes building products and doing research — are getting the few good jobs, leaving everyone else to fight for scraps.
“There’s definitely a very dreary mood on campus,” said a recent computer science graduate who asked not to be named so they could speak freely. “People [who are] job hunting are very stressed out, and it’s very hard for them to actually secure jobs.”
The shake-up is being felt across California colleges, including UC Berkeley, USC and others. The job search has been even tougher for those with less prestigious degrees.
Eylul Akgul graduated last year with a degree in computer science from Loyola Marymount University. She wasn’t getting offers, so she went home to Turkey and got some experience at a startup. In May, she returned to the U.S., and still, she was “ghosted” by hundreds of employers.
“The industry for programmers is getting very oversaturated,” Akgul said.
The engineers’ most significant competitor is getting stronger by the day. When ChatGPT launched in 2022, it could only code for 30 seconds at a time. Today’s AI agents can code for hours, and do basic programming faster with fewer mistakes.
Data suggests that even though AI startups like OpenAI and Anthropic are hiring many people, it is not offsetting the decline in hiring elsewhere. Employment for specific groups, such as early-career software developers between the ages of 22 and 25 has declined by nearly 20% from its peak in late 2022, according to a Stanford study.
It wasn’t just software engineers, but also customer service and accounting jobs that were highly exposed to competition from AI. The Stanford study estimated that entry-level hiring for AI-exposed jobs declined 13% relative to less-exposed jobs such as nursing.
In the Los Angeles region, another study estimated that close to 200,000 jobs are exposed. Around 40% of tasks done by call center workers, editors and personal finance experts could be automated and done by AI, according to an AI Exposure Index curated by resume builder MyPerfectResume.
Many tech startups and titans have not been shy about broadcasting that they are cutting back on hiring plans as AI allows them to do more programming with fewer people.
Anthropic Chief Executive Dario Amodei said that 70% to 90% of the code for some products at his company is written by his company’s AI, called Claude. In May, he predicted that AI’s capabilities will increase until close to 50% of all entry-level white-collar jobs might be wiped out in five years.
A common sentiment from hiring managers is that where they previously needed ten engineers, they now only need “two skilled engineers and one of these LLM-based agents,” which can be just as productive, said Nenad Medvidović, a computer science professor at the University of Southern California.
“We don’t need the junior developers anymore,” said Amr Awadallah, CEO of Vectara, a Palo Alto-based AI startup. “The AI now can code better than the average junior developer that comes out of the best schools out there.”
To be sure, AI is still a long way from causing the extinction of software engineers. As AI handles structured, repetitive tasks, human engineers’ jobs are shifting toward oversight.
Today’s AIs are powerful but “jagged,” meaning they can excel at certain math problems yet still fail basic logic tests and aren’t consistent. One study found that AI tools made experienced developers 19% slower at work, as they spent more time reviewing code and fixing errors.
Students should focus on learning how to manage and check the work of AI as well as getting experience working with it, said John David N. Dionisio, a computer science professor at LMU.
Stanford students say they are arriving at the job market and finding a split in the road; capable AI engineers can find jobs, but basic, old-school computer science jobs are disappearing.
As they hit this surprise speed bump, some students are lowering their standards and joining companies they wouldn’t have considered before. Some are creating their own startups. A large group of frustrated grads are deciding to continue their studies to beef up their resumes and add more skills needed to compete with AI.
“If you look at the enrollment numbers in the past two years, they’ve skyrocketed for people wanting to do a fifth-year master’s,” the Stanford graduate said. “It’s a whole other year, a whole other cycle to do recruiting. I would say, half of my friends are still on campus doing their fifth-year master’s.”
After four months of searching, LMU graduate Akgul finally landed a technical lead job at a software consultancy in Los Angeles. At her new job, she uses AI coding tools, but she feels like she has to do the work of three developers.
Universities and students will have to rethink their curricula and majors to ensure that their four years of study prepare them for a world with AI.
“That’s been a dramatic reversal from three years ago, when all of my undergraduate mentees found great jobs at the companies around us,” Stanford’s Liphardt said. “That has changed.”
