Nine children have been infected with E. coli O157 after exposures at Capitola Beach or the waterways around it in Santa Cruz County, California, and as of November 11, 2026, two of them had been hospitalized and, according to County Health Officer Dr. Lisa Hernandez, all nine have recovered. Four of the children live in Santa Cruz County and five in other Bay Area counties. No deaths have been reported. The source has not been found and the beach remains closed. Marler Clark has been retained by the family of one of the children, who developed acute kidney failure, and we have opened our own investigation.
All nine cases are linked, and the county says the exposures happened at the beach or in the surrounding water.
The Santa Cruz County release of November 10 says all nine infections are linked, which points to a common source, and that all exposures likely occurred at Capitola Beach or in surrounding waterways. It gives no ages, onset dates or exposure dates, and does not mention hemolytic uremic syndrome. Good Times ran the release with a photograph of a sign at the beach warning that creek water may be contaminated, a sign that has been part of the scenery at Capitola for a long time. I wrote about what the county had and had not said on Marler Blog that day.
Two children were hospitalized and all nine have recovered.
The new facts came the next evening. In a KSBW interview published November 11, Dr. Hernandez said there were two known hospitalizations linked to the outbreak and that “fortunately, no deaths [were] associated with this outbreak. All individuals have recovered.” I hope that holds. The child whose family has retained us developed acute kidney failure, which is hemolytic uremic syndrome by another name, and a child who has been through HUS is not recovered in the way a child who had three days of cramps is recovered. Kidney damage from HUS can show up years later as high blood pressure, reduced kidney function and, in some, dialysis or transplant. The county’s release did not mention HUS at all.
| Capitola Beach E. coli O157 outbreak | Count | Source |
| Santa Cruz County residents | 4 | County release, Nov 10 |
| Residents of other Bay Area counties | 5 | County release, Nov 10 |
| Total cases, all children | 9 | County release, Nov 10 |
| Hospitalized | 2 | Dr. Hernandez to KSBW, Nov 11 |
| Recovered | 9 (all) | Dr. Hernandez to KSBW, Nov 11 |
| Deaths | 0 | Dr. Hernandez to KSBW, Nov 11 |
Counts as of November 11, 2026. Check: 4 Santa Cruz County residents + 5 other Bay Area residents = 9, which matches the county’s total.
The county sampled four sites and cannot promise it will find the source.
Environmental Health sampled four points along Soquel Creek and the beach: upstream near Nob Hill, the jetty, Soquel Creek Lagoon and the flume where the creek enters Monterey Bay, and Dr. Hernandez told KSBW that soil, water and fecal samples have gone to CDC. She also said she “can’t promise that we’ll have a source,” which is honest: the contamination that made the children sick may be long gone by the time the first case is reported.
Soquel Creek has been on California’s impaired-waters list for pathogens since 1996.
None of this is new to the creek. Soquel Lagoon, the body of water the creek forms behind Capitola Beach, was placed on the Clean Water Act 303(d) list of impaired waters for pathogens in 1996. In 2008 the Central Coast Regional Water Quality Control Board adopted a fecal coliform cleanup plan for the lagoon, the creek and Noble Gulch, and listed the controllable sources in order: storm drain discharges carrying animal and human waste, sanitary sewer spills and leaks including private laterals, pet waste, and homeless encampments along the creek. The responsible parties it named were the City of Capitola, the County of Santa Cruz, the county sanitation district and private sewer-lateral owners, with thirteen years to comply.
Capitola Beach sat on Heal the Bay’s list of the twenty worst beaches in California from 2001 through 2004 and again in 2009, and the lagoon is permanently posted as unsafe for human contact. In 2009 the city spent a $600,000 state Clean Beaches grant on a treatment wetland beside the lagoon; the project’s own 2010 report found E. coli above the state guideline at the beach in every monitoring round before and after construction and called the wetland’s effectiveness limited. In Heal the Bay’s 2020–21 report card Capitola was the third most polluted beach in the state, with routine F grades; Capitola’s public works director put it simply: Soquel Creek runs into the middle of the beach and the water does not circulate. Lookout Santa Cruz told readers that summer to swim at least a hundred yards from the creek mouth. The sign in the Good Times photograph is the same warning, thirty years on.
One caution. Those grades measure indicator bacteria, which say fecal contamination is present. They do not detect E. coli O157, a specific strain carried mostly by cattle and other ruminants and sometimes by deer, birds and people. A creek can fail indicator tests for decades without O157 ever appearing. The question is not whether the creek is dirty, which was answered in 1996, but where the O157 came from this fall and who knew what about the water when children were in it.
What Marler Clark is doing to investigate.
We have represented children with HUS from recreational water for many years, most recently at Sycamore Pool in Chico, and the work is the same each time. We are gathering our client’s medical records and the stool culture and whole genome sequencing results from the California Department of Public Health lab, so that the outbreak strain can be compared to anything the county or CDC finds in the creek, the lagoon or the sand. We are requesting, under the California Public Records Act, the county’s and the city’s environmental sampling results from all four sites, their beach posting and closure records for the weeks before the closure, the sanitation district’s sewer spill and overflow reports for the Soquel Creek watershed this fall, and the illness onset and exposure dates the county has not released. We are asking the families of the other eight children to contact us, not because every family needs a lawyer, but because the exposure dates and the places each child went in the water are the data that locate a source. And we have retained environmental and microbiological experts to look at the creek, its storm drains and what sits upstream of Nob Hill.
The beach is still closed, and people were in the water anyway.
Closure signs stay up until the county says the beach can reopen. KSBW’s reporter watched surfers and several young children wading in the surf on November 11 anyway. Until the closure is lifted, stay out of the water inside the posted area, keep children and pets out of the creek and lagoon, and never let a child drink from a creek or lagoon.
E. coli O157 symptoms start three to four days after exposure and the kidney complication comes about a week later.
Most people infected with E. coli O157 get sick three to four days after swallowing the bacteria, with a range of one to ten days. The illness usually begins with severe stomach cramps and diarrhea that often turns bloody, sometimes with vomiting and a low fever, and most people recover in five to seven days. The danger is hemolytic uremic syndrome, which develops in roughly five to ten percent of diagnosed O157 infections, most often in children under five, usually about a week after the diarrhea starts and often as it is improving. Warning signs are urinating less often, extreme tiredness and losing the pink color in the cheeks and inside the lower eyelids; a child with those signs needs an emergency room. Do not give antibiotics or anti-diarrheal medicine for a suspected O157 infection unless a doctor who knows the diagnosis says so.
Is Capitola Beach open?
No. As of November 11, 2026, the beach is closed on the recommendation of the county health officer, with no reopening date; the county says it will notify the public when it reopens.
My child swam at Capitola Beach. What symptoms should I watch for?
Severe cramps, diarrhea that may turn bloody, vomiting and a low fever, usually three to four days after exposure and up to ten. Call a doctor for bloody diarrhea; go to an emergency room for decreased urination, unusual tiredness or pale skin, which can signal HUS.
Can E. coli O157 from a beach spread to other people in my house?
Yes. The bacteria spread in stool and a child can be contagious for a week or more after recovering. Soap-and-water handwashing and keeping sick children out of daycare and pools are the protections.
