The Brief

In 2024, a group of Southeast L.A. residents filed a lawsuit against Sterigenics, a company operating in Vernon that uses a controversial chemical to sterilize medical equipment.

On Thursday, those plaintiffs cleared a key hurdle that now paves the way for their case to potentially move forward to a trial or settlement.

Residents say Sterigenics has knowingly exposed them and their neighbors to unsafe levels of ethylene oxide for decades, without warning them of the potential health risks. Ethylene oxide is a colorless gas that’s central to the sterilization process — it’s also a known carcinogen.

Residents say the company is responsible for their cancer diagnoses, or for the deaths of their loved ones.

In the nearly two years that residents have been seeking relief from the court, dozens of other local residents have also filed lawsuits against the company, along with people who were diagnosed with cancer after working at a business that operates next to Sterigenics.

The company, which has denied wrongdoing, filed several motions for summary judgment against the plaintiffs — a legal tool that can be used to keep cases from going to trial.

But after two days of back and forth in a downtown L.A. courthouse, Judge Lawrence Riff denied all the motions.

What kind of relief do residents want?

Most of the plaintiffs in the original case have been diagnosed with breast cancer. The others — including a toddler and a man who fell ill when he was in high school — have been diagnosed with leukemia, non-Hodgkin’s lymphoma, stomach cancer or other conditions. The plaintiffs also include long-term Maywood residents who’ve lost a parent or spouse. All of them have lived less than a mile away from Sterigenics.

Court documents show that the Maywood residents want a jury trial and seek compensation for past and future medical expenses, funeral costs, lost wages, and the fear and “mental anguish” of being sick or watching a family member die.

Their lawsuit also asks Sterigenics to:

• keep its emissions “within health-protective standards”; 
• immediately notify regulators when their equipment breaks down;
• provide real-time reporting of its emissions to community members;
• and pay additional penalties to deter the company from committing future violations.

The group filed its lawsuit against Sterigenics and its affiliates in March 2024. Other residents filed at least six more lawsuits later in 2024 and 2025. Two more local lawsuits have been filed against the company this year. Plaintiffs in these other cases seek similar compensation.

There are currently two trial dates set for the original case: Jan. 25, 2027, and April 15, 2027.

What is Sterigenics’ history in LA?

Sterigenics runs two facilities in Vernon. Every year, the company sterilizes more than 45 million medical supplies, including surgical kits, syringes, heart valves, and pacemakers. These products then go out to nearly 100 healthcare manufacturers.

Vernon is a small, largely industrial city located five miles southeast of downtown L.A. Maywood is an adjoining city with more than 23,000 residents, most of whom are Latino and working class.

At the hearings this week, attorneys for Sterigenics and its parent company, Sotera Health, insisted there’s not enough ethylene oxide flowing in the neighborhood to cause cancer.

According to Judge Riff, the methodology of an expert Sterigenics relied on was “not sufficiently reasoned,” in part because her assessment of ethylene oxide emissions in the area surrounding the facility did not account for changes over multiple decades.

LAist has reached out to Sterigenics for further comment.

Southern California was built on radio.

"I can still hear the jingle KFWB News 98,” wrote  Taline in Los Feliz, during a recent conversation on LAist's daily news show, AirTalk, which airs on 89.3 FM. “I grew up hearing that in my dad's minivan on the way to and from school. It has a special place in my heart.”

Back in April, broadcast company Audacy announced KNX News — one of the last-remaining all-news FM stations — was leaving the FM dial where it had simulcast on 97.1 FM since 2021. The station, which is also one of the oldest in L.A., is not budging from 1070 AM where it has been on the air for more than 100 years. The move away from FM officially happened in May to make way for a new sports talk station, which Audacy officials called an area of growth for advertisers in today’s media landscape.

The move is one in a long line of changes for radio and a reminder that before podcasts, playlists and algorithms, many Southern Californians built their days around radio broadcasts.

Larry Mantle, now in his 41st year hosting AirTalk, remembers being a kid and dreaming of what it might be like to be behind the mic at one of these radio stations.

“ I grew up with KNX," he said. “My dream job as a kid was to be an anchor on KNX or KFWB, the two local all-news radio stations, 'cause there was nothing like hosting AirTalk that even existed at that point.”

Mantle opened up the phone lines on a recent show to hear from his fellow SoCal radio lovers about the shows they miss and the memories they have. Here's what they had to say:

“When you'd walk down Hollywood Boulevard where the station was, you could hear it playing as you went down the street,” said  Olivia in Glendale about KLAC 570 with Al Jarvis.

 Larry in Yorba Linda shouted out KBCA Jazz for its 24-hour jazz, saying “When I first moved out here in '68 from Phoenix, which had like an hour a week, it was a real wonder.”

 Mark in Glassell Park emailed that he loves KCRW’s Henry Rollins, writing, “I used to bristle at his unique DJ persona, but over time, I came to love him and his crazy eclectic playlists. I find his knowledge in history and punk rock fascinating. He's a gem and a legend."

"I'd like to give a shout-out to all the DJs working at KXLU, the college station at Loyola Marymount University, said  Jeremy in Culver City in an email. “That station's been on the air for nearly 60 years. I believe it's one of the best examples of what's possible with radio."

"KFWB and KRLA back in the day when they were rock music stations —  Dr. Demento, one of my favorite on-air personalities, also had eclectic music taste," said  Carrie in Desert Edge.

“ Dr. Demento was must listening when I was a kid in junior high school at Le Conte Junior High in Hollywood,” Mantle added. “Every Sunday night on KMET, we would make sure we were listening to Dr. Demento and his funny records.”

The question remains…

Listener support is vital to any radio station, and it’s clear KNX has many lifelong fans. AirTalk listeners highlighted their support for household KNX names over the decades like Bill Keene, Melinda Lee, Mike Roy and Jackie Olden.

As KNX makes changes, many are watching closely and thinking about the future of radio.

Listeners like Tommy in La Quinta are left wondering if the radio dial will be the same…

“I’m a hardcore listener, but I don't know about casual listeners [and] if they'll tune to AM,” he said.

After months of hand-wringing, Los Angeles and LA28 have come to a tentative agreement on how Olympics organizers will reimburse the city for its expenses for the 2028 Summer Games.

According to the deal, the private Olympic organizing committee will pay upfront for the estimated cost of services that are not eligible for federal reimbursement, like trash pick-up and traffic control. Under another proposal, the city would also be able to tap an LA28 contingency fund if it isn't fully repaid by the federal government for policing costs at Olympic venues.

The agreement is nearly nine months overdue and still needs approval by Mayor Karen Bass and the City Council.

The 2028 Olympics are intended to be privately financed, and an existing city agreement with LA28 states that the Olympics organizers, not L.A., will pay for extra costs for public services in support of the Games. But L.A. is the financial back-stop for the Olympics, meaning if LA28 goes in the red, taxpayers will pick up the bill.

Beyond that, the city services agreement presents another area where L.A. could incur additional unexpected expenses for hosting the Games. L.A. City Councilmember Monica Rodriguez warned LA28 CEO Reynold Hoover earlier this year that a bad deal could "bankrupt" the city.

Jacie Prieto Lopez, an LA28 spokesperson, and Paul Krekorian, who leads the city's office of major events, said in statements that the freshly inked agreement would help deliver a fiscally responsible Games.

"Mayor Bass’ priority is that the 2028 Olympic and Paralympic Games be fiscally responsible, protect taxpayers, and benefit Angelenos for decades to come. This agreement helps deliver that commitment," Krekorian said.

But the contract between the two parties doesn't fully resolve one of the biggest areas of financial risk for the city: the enormous cost of security for an event as extensive and high-profile as the summer Olympics and Paralympics.

Organizers are counting on the federal government to pay for public safety at Olympic venues that are considered part of a "national special security event." That includes costs for LAPD staffing. LA28 has not included security costs in its $7.1 billion budget — a fact that City Attorney Hydee Feldstein Soto criticized earlier this year.

The federal government has so far allocated $1 billion for security costs for the Olympics. Exactly where those federal funds will go has not yet been determined, and there's no guarantee they will cover all of L.A.'s policing costs.

To address this, city officials have also proposed an amendment to a 2021 agreement between the city and LA28. That amendment would establish that if L.A. is not reimbursed by the federal government for all its eligible expenses, it could dip into LA28's contingency fund of $270 million before the private organizing committee could use those funds for any legacy projects.

But that bucket of money will first be used for any costs that Olympics organizers still owe if they run out of revenue — meaning if the Olympics don't turn a profit, the city's access to that money will depend on how much is left for the taking.

Civil rights attorney Connie Rice, who has been tracking the city's negotiations with LA28, told LAist the agreement was a "PR document" not a deal. She pointed out that if the federal government does not pay up for security spending as expected, L.A. could be in trouble.

" It leaves the taxpayers with a GoFundMe strategy," she said.

The city services agreement lays the groundwork for more negotiations between LA28 and the city. Each venue will require its own agreement, to be negotiated by July 1, 2027. Venues in the city of L.A. include Dodger Stadium, the L.A. Convention Center, L.A. Memorial Coliseum and the Venice Beach Boardwalk.

The City Council's ad-hoc committee on the 2028 Games will meet Tuesday afternoon to vote on the agreement.
