Mussel Quarantine in Effect
The California Department of Public Health (CDPH) Director and State Public Health Officer have enacted the annual quarantine on mussels gathered by sport harvesters along the California coast. The quarantine is declared due to the possibility of Paralytic shellfish poisoning (PSP). PSP is a form of nervous system poisoning caused by consuming shellfish which have bio-accumulated toxins from various microscopic ocean flora. Concentrated levels of the toxins can develop in mussels and other bivalve shellfish when they feed on certain naturally occurring marine plankton.
The annual quarantine on sport-harvested mussels, typically runs May 1 through October 31 and is intended to protect the public from shellfish poisoning caused by marine biotoxins.
The most current information on shellfish advisories and quarantines is available by calling CDPH’s toll-free Shellfish Information Line at (800) 553-4133. For additional information, please visit the CDPH Marine Biotoxin Monitoring Web page.
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 October 19th, 2017 by the County of Santa Cruz, detected microcystin toxin at Villas del Paraiso dock at 5 parts per billion (ppb). Samples taken at the County fishing dock did not detect microcystin toxin (detection limit is 1 part per billion [ppb]), however some visible microcystis colonies have started to form. Kelly Lake was also tested on October 19th, 2017. Microcystin toxin was detected at a concentraion of 5 ppb. Humans and pets are advised to avoid body contact at areas with any detectable concentration.
Samples taken by the City of Watsonville on October 11, 2017 detected no microcystin toxin at the City boat launch dock. (Detection limit is 1 part per billion [ppb]).
