2026 Suicide Prevention Month Posted on August 11, 2026 September is Suicide Prevention Month! For 2025, San Mateo County and partners are promoting the statewide theme: “Support, Your Way.” What if suicide prevention could feel human, honest, and self-assured, all while being inclusive of the different ways people can find support. Rather than centering fear, crisis, or clinical language, this theme is about agency, particularly at vulnerable moments when people feel like they have none. It reflects a cultural truth that people want help on their own terms, and flips the understanding of asking for help not as a loss of control—but as a regaining of it. It’s not about prescribing what help should look like. It’s about validating the choice to reach out for help, understanding that support can look different for everyone, and reframing the act of asking for support as taking control—not losing it. Support, Your Way- Tips and Reminders: Getting help means taking control. Asking for support isn’t a breakdown. It’s a breakthrough—and it can look like whatever you need it to. Support looks different for everyone. Some people talk to a peer. Some text 988. Some open up to a friend. Some start therapy. For some, it’s a mix of all of these options. There’s no one-size-fits-all. You get to choose what feels safe. You don’t need to wait for a crisis. Reaching out before things spiral is just as valid as reaching out in an emergency. It’s always the right time to check in or ask for help. There’s no wrong way to ask for help. Even if you don’t know what to say. Even if it’s messy. Each year, San Mateo County Behavioral Health & Recovery Services’ Office of Diversity & Equity (ODE) and Suicide Prevention Committee (SPC) promotes free events throughout the month of September to promote Suicide Prevention Month. All events are free and open to the public. This year’s events will be in-person and/or virtual.

Shellfish Safety Posted on December 23, 2025February 27, 2026 San Mateo County’s Mussel Sampling Program Approximately every two weeks Environmental Health Services staff collects mussel and plankton samples along San Mateo County’s coastline as part of the State’s Mussel Sampling Program. The mussel samples are sent to the California Department of Public Health and tested for unsafe levels of naturally occurring toxic materials known as “biotoxins.” Results are published once a month to keep the public informed on when it’s unsafe to eat mussels and other shellfish. Why are biotoxins in shellfish dangerous? Certain species of algae (phytoplankton) produce naturally occurring biotoxins that can become too abundant in shellfish like mussels, clams, oysters, crabs, and lobsters. Shellfish consumed with unsafe levels of biotoxins can cause paralytic shellfish poisoning, domoic acid poisoning, and other health issues that may pose a serious threat to humans and wildlife, including death. When is it safe to eat recreationally harvested mussels in San Mateo County? Never assume mussels are safe to eat. While a quarantine on mussels takes effect annually from May 1st – October 31st as a safety precaution, the quarantine may become extended or take effect at any time of the year. Please call the biotoxin hotline at 1-800-553-4133 before including mussels or any shellfish on your menu. Quarantine Boundaries The quarantine extends from the California-Oregon boundary south to the California-Mexico boundary and applies to all bays, inlets, and harbors. Using Mussels as Bait Mussels for use as bait shall be broken open at the time of taking, or prior to sale at the discretion of the enforcing agency. Mussels used as bait should be placed and sold in containers adequately labeled in large bold faced letters that are at least a half an inch in size. Clams Clams should be washed thoroughly and cooked. All dark parts of the clams and scallops must be discarded because biotoxin is concentrated in the dark parts if present. Only the white meat of clams and scallops should be prepared for human consumption.

Lyme Disease & Tick Testing Posted on August 8, 2025February 27, 2026 The incidence of Lyme Disease in San Mateo County is very low. The microorganism that causes Lyme Disease, Borrelia burgdorferi, is not common among ticks in San Mateo County. Young ticks, or nymphs, are more likely than adults to be infected. The nymphs often clear the infection by the time they reach adulthood. The San Mateo County Mosquito and Vector Control District conducts annual tick collection and testing at popular hiking trails throughout the County. SMCMVCD regularly finds that less than 5% of ticks collected in San Mateo County carry the Lyme disease bacteria. Even if you are bitten by an infected tick, it’s difficult to get Lyme Disease. The tick must be feeding on you for 24 to 48 hours to effectively transfer the microorganism from its stomach to your body. If you find a tick attached to you or your pet, don’t panic. Carefully remove and save the tick. If you would like to have the tick tested, please contact the County of Santa Clara Public Health Laboratory at 408-885-4272 or visit Santa Clara Public Health Lab site for more information. San Mateo County’s Public Health Lab does not offer tick testing.
San Mateo County Health Responds to New Mpox Strain Posted on August 7, 2025February 27, 2026 Risk to public remains very low Redwood City – San Mateo County Health is working with state and federal partners in responding to a case of clade I mpox, the first known case in the United States. Confirmed through laboratory testing, the case is related to an ongoing outbreak of clade I mpox in Central and Eastern Africa and was acquired through travel. The risk of exposure for the public to clade I mpox remains very low, but there continue to be sporadic clade II mpox cases in the United States. Since 2022, County Health has responded to the global outbreak of clade II mpox. Outbreaks from the different subclades, or genetic branches, can have different characteristics, including whom they affect and how they’re spread. Although clade II mpox has been circulating in the United States since 2022, clade I mpox has never been reported in the United States until now. Historically, clade I mpox has caused more severe illness and deaths than clade II mpox. San Mateo County Health is assisting the California Department of Public Health and the Centers for Disease Control and Prevention on tracing and notifying close contacts of potential exposure. To date, 108 cases of clade II mpox have been reported in San Mateo County. “While clade I may be new to the United States, we and other counties have been responding to mpox since 2022 with contact tracing, guidance and vaccine support,” said San Mateo County Health Officer Dr. Kismet Baldwin-Santana. “Our work continues, with the support of our state and federal partners.” With mild illness, the individual is isolating at home and recovering. There is no concern or evidence that mpox clade I is currently spreading among individuals in San Mateo County or elsewhere in the United States. Transmission typically spreads from close (skin to skin), intimate and sexual contact. Casual contact, such as during travel, in an office or classroom or in a store, is unlikely to pose significant risks for transmission of mpox. Travelers to countries experiencing clade I outbreaks should consult with their primary care provider. “Given the very low risk to the public of exposure to clade I,” said Dr. Baldwin-Santana, “the standing guidance for preventing mpox has not changed.” Persons who have certain risk factors should consult with their primary health care provider about vaccination and take steps to reduce exposure, including avoiding close, skin to skin contact with people who have a rash that looks like mpox and avoid contact with objects and materials that a person with mpox has used. More information about mpox is available from the California Department of Public Health and the Centers for Disease Control and Prevention.
Bird Flu Posted on August 7, 2025February 27, 2026 H5N1, also known as bird flu, has been circulating in California since 2022 and is present in the Bay Area. While the risk of infection in people is low, those who are routinely in close contact with birds or dairy cows should take steps to protect themselves from exposure. Bird flu has been detected in a local backyard flock. While there are currently no human cases of H5N1 from this instance, San Mateo County’s Department of Agriculture/Weights and Measures is advising backyard poultry owners to watch for signs of avian influenza in their flock and to take appropriate biosecurity measures such as washing hands before and after handling birds and disinfecting footwear to reduce the risk of spreading bird flu. What can you do? People who have job-related or recreational exposure to infected animals, such as wild birds, poultry and dairy cows or products from infected animals, are at greater risk of being exposed to H5N1. These people may include farmers or workers on poultry and dairy farms, slaughterhouse workers, workers handling milk or other animal products, backyard bird flock owners, veterinarians and veterinary staff. These people should: Follow all recommendations from the Centers for Disease Control and Prevention (CDC) for worker protection to reduce the risk of infection, including wearing personal protective equipment when appropriate. Call your doctor if you feel sick. Symptoms of H5N1 bird flu can include cough, sore throat, fever and red or watery eyes. Others who have close contact with these types of animals, animal products or the surrounding areas should also consider wearing PPE such as an N95 mask, gloves and eye protection. While the current risk to the general public from H5N1 bird flu is low, the CDC recommends: Do not drink unpasteurized (raw) milk or prepare or eat raw milk products like raw cheese. Raw milk and cheese have not been pasteurized to kill disease-causing germs. Avoid unprotected exposures to sick or dead animals, including wild birds, poultry and other domesticated birds. Handling sick or dead animals safely requires personal protective equipment and training. San Mateo County Health continues to work with the San Mateo County Department of Agriculture/Weights & Measures to make sure the local agricultural industry has information and guidance.
Gov. Newsom Affirms County’s Ambitious Vision on Behavioral Health Treatment Posted on May 28, 2024June 23, 2026 Test Caption for the photo Redwood City – Gavin Newsom on Tuesday commended County officials for an ambitious project that reflects the governor’s twin priorities: improving mental health treatment and combatting the homelessness crisis. “San Mateo (County) has stepped up,” Newsom said after touring the Cordilleras Health and Healing Campus, which will replace an Eisenhower-era concrete mental health treatment hospital. “Now it’s time for other counties to do the same.” Newsom selected Cordilleras as the backdrop for announcing the state is accelerating the first round of funding, made available by Prop. 1, to boost California’s transformation of the statewide behavioral health system. That transformation is unfolding between San Carlos and Redwood City, where the new Cordilleras campus is rising amid rolling hills, oak trees and chirping birds. It will provide locked treatment areas for the most vulnerable patients in small-homelike settings, along with adult residential care focusing on behavioral health rehabilitation and recovery. “We never have been and we never will be about the brick and mortar. It is about people, our clients and serving them in a dignified and respectful way. And this is what we will be doing in these buildings,” Mike Callagy, the County’s chief executive officer, said during a news conference with Newsom. Key to the County’s system of inpatient and outpatient treatment centers that address mental health needs and keep the most vulnerable residents off the streets, the campus replaces a facility first opened as a tuberculosis hospital in the 1950s. By 1978, the building was rededicated to mental health treatment thanks to the efforts of local family members of people with mental illness, who were the founders of the organization that eventually became NAMI, the National Alliance on Mental Illness. The new Health and Healing campus reflects fresh thinking in how surroundings affect mental health. When it opens later this year, the campus will include a total of 121 beds arrayed in smaller living units with windows that provide landscape views and outdoor areas that offer fresh air and sunlight. The current buildings will be torn down to make way for open spaces. In selecting Cordilleras for Tuesday’s news conference, the governor’s office said, “Treatment centers and campuses like the one highlighted today will be possible all across the state” due to the passing of Prop. 1 on the March 2024 ballot. “Prop. 1 and the vision the governor outlined affirm the hard work, dedication and commitment of a generation of San Mateo County leaders and community members and their tireless advocacy for mental health care services. It’s their legacy we are building on,” said Jei Africa, director of Behavioral Health and Recovery Services. Additionally, Newsom announced the launch of MentalHealth.CA.gov, a one-stop website for people seeking mental health resources available to Californians. This will help Californians see how their own county government is using the tools and resources already available to them. “Prop. 1 encourages counties to be ambitious about behavioral health care services and to address the root causes of the many challenges our communities face,” Callagy said. “And now we can dream bigger.” Media Contact Preston Merchant Communications Officer San Mateo County Health 650-867-1661 press@smchealth.org
