Annual Mussel Quarantine in Effect
The annual mussel quarantine, declared by the California Department of Public Health (CDPH), began May 1, 2016. This quarantine applies to all species of mussels sport-harvested along the California coast, as well as all bays and estuaries.
This quarantine is intended to prevent paralytic shellfish poisoning (PSP) and domoic acid poisoning (DAP) in people who might otherwise consume sport-harvested mussels. Both of these toxins are linked to plankton consumed by filter-feeding animals such as bivalve shellfish, including mussels and clams. The majority of human cases of PSP illnesses occur between spring and fall.
This quarantine does not apply to commercially harvested shellfish.
More information about the quarantine, PSP and DAP can be found on the CDPH Annual Mussel Quarantine - Frequently Asked Questions (FAQ) Web page.
For updated information on quarantines and shellfish toxins call the CDPH Biotoxin Information Line (1-800-553-4133).
PINTO & KELLY LAKES ADVISORY
Pinto and Kelly Lakes are subject to blooms of blue-green algae (cyanobacteria). Cyanobacters such as microcystis are known to produce toxins, exposure to which can cause rashes, skin and eye irritation, allergic reactions, gastrointestinal upset, and other effects. At high levels, exposure can result in serious illness or death. Exposure may occur by ingestion, dermal contact or inhalation. Avoid body contact with blue-green algal blooms. This includes swimming, wading and water-skiing. Also do not allow your pets to enter the water. For more information visit the California Department of Public Health here.
The most recent sample results, taken September 21, 2016 by the City of Watsonville has detected microcystins toxin levels greater than 20 parts per billion (ppb) at the City of Watsonville boat launch ramp at Pinto Lake (detection limit is 1 part per billion [ppb]). The dock will be cordoned off and remain cordoned off until toxin levels drop below 10 ppb.
Other samples taken by the County of Santa Cruz on September 23, 2016 showed: >20 ppb at Kelly Lake, >10 ppb at the Villas del Paraiso dock, >10 ppb at the County dock, >10 ppb at the kayak haul-out next to the County dock, and <1 ppb net to disc golf hole #14.
The County of Santa Cruz Environmental Health Service provides water quality information to concerned swimmers to alert them to areas that may be contaminated by fecal indicator bacteria.
