Chico City Faces Legal Action After E. coli Infection Among Children at Local Pool

In July 2025, four children, aged one to thirteen, fell seriously ill due to E. coli O157:H7 infections after swimming in Sycamore Pool and the nearby Bidwell Park in Chico, California. Their families have now filed a lawsuit against the City of Chico, claiming negligence in maintaining public health standards at the pool. This incident has sparked outrage among residents and raised questions about safety protocols at city-run recreational facilities.

Background of the Incident

All four children were hospitalized after enjoying a day at the pool, where they were exposed to the dangerous bacteria that also contaminated the sediment in the swimming area. The situation worsened for three of the children, who developed hemolytic uremic syndrome, a severe complication of E. coli infection, requiring extensive medical interventions and prolonged hospital stays.

William Marler, a prominent attorney specializing in food safety and representing the families, highlighted the severity of the situation. "A thirteen-year-old was airlifted out of Chico and spent fifteen days on dialysis. That’s not just a statistic; these are young children who’ve suffered due to systemic neglect," Marler explained. The lawsuit underscores the striking correlation between their illnesses and the bacteria found in the water tested by the CDC following the incident.

Legal Allegations Against the City

The lawsuit centers on several alleged failures by the City of Chico, particularly its gross negligence in running safety checks and adhering to health regulations mandated for public recreational spaces. According to the lawsuit, the city had undergone nearly three decades without the proper permit to clean Sycamore Pool. Furthermore, despite clear evidence of bacterial contamination in the waters — highlighted by a specific reading of 461 E. coli in May 2025 — the city continued to operate the pool without implementing the necessary safety protocols.

Adriana Zimova, counsel for the plaintiffs, noted, "The evidence shows a clear pattern of negligence regarding water safety regulations, with repeated exceedances of permissible E. coli levels noted prior to the cases that impacted these children."

For years, the recreational waters of the Big Chico Creek, which feeds into the pool, had registered unhealthy bacterial levels, yet the city failed to act accordingly. Legal guidelines mandated that testing should be conducted weekly, and more rigorous daily testing should have occurred when E. coli thresholds were surpassed.

The City’s Responsibility

Sycamore Pool, a 600-foot long facility cherished by families since its opening in 1924, is an intrinsic part of Chico's recreational offerings. The city manages everything from maintenance to staffing, yet its public safety track record is now under scrutiny. Marler further accused the city of failing to adequately address known health risks associated with the pool, stating, "The city effectively advertises this pool as a safe space for children while neglecting its own safety requirements."

Amidst this pressing lawsuit, families not only seek compensation for medical expenses incurred due to the illness but also hope to hold the City of Chico accountable for neglecting its public health duties. They ask for a jury's recognition of the damages suffered by these children, which have had both immediate and potential long-term implications on their health and wellbeing.

Conclusion

The upcoming legal battle may not just resolve the fates of these families but also catalyze a broader conversation about the responsibilities of city officials to maintain public safety in recreational environments. As discussions about food and waterborne illness safety elicit public interest, all eyes will be on how this case unfolds in the courts. The tragedy that hit this small group of children serves as a bitter reminder of the vital importance of adhering to health safety protocols — especially in places frequented by vulnerable populations like young children.
