 Advisories and Closures: Week of July 27, 2015

Cowell Beach, west of the wharf, extending to the east end of the Dream Inn, has  E. coli levels above the safe body contact standard. Advisory signs have been placed at beach entry points.

Main Beach, from the wharf extending west to Tower 2 has elevated E. coli levels. Advisory signs have been placed in the affected areas.

  All other beaches tested this week met safe body contact standards.

The San Lorenzo River, at the Big Trees entrance to Henry Cowell Redwoods State Park, has  E. coli levels above the safe body contact standard. Advisory signs have been placed at river entry points.

THE FOLLOWING AREAS ARE PERMANENTLY POSTED BY THE COUNTY DUE TO ROUTINELY HIGH BACTERIA LEVELS:

 Aptos Creek at Rio del Mar Beach

Porter Gulch Creek at New Brighton Beach

Soquel Creek mouth at Capitola Beach

Schwan Lagoon at Twin Lakes Beach

San Lorenzo River mouth

Neary Lagoon at Cowell Beach  

 THESE WATER BODIES AND ADJACENT AREAS GENERALLY CONTAIN BACTERIA LEVELS ABOVE SAFE BODY CONTACT STANDARDS AND ARE CONSIDERED UNSAFE FOR BODY CONTACT. 

 

  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. For more information visit the California Department of Public Health here.

A blue-green algae bloom is currently underway at Pinto Lake. The most recent sample results, taken July 30, 2015, show microcystins toxin detected in the 0.5 to 1.5 part per billion (ppb) range. (Detection limit is 0.5 parts per billion [ug/L].) 

 

Mussel Quarantine in Effect

The annual mussel quarantine is in effect. The annual quarantine applies to sport-harvested mussels for the entire California coast, including all bays and estuaries. This quarantine period, from May 1st through October 31st, is based on the potential for red tides during these months. Each year, Santa Cruz County experiences several red tides, some of which can turn shellfish meats toxic. Sport harvesters should call the Biotoxin Information Line at 1-800-553-4133 for the current status of all quarantines and health advisories before harvesting and consuming shellfish. This quarantine does not apply to commercial shellfish purchased in stores and restaurants.

California Department of Public Health (CDPH) has issued an additional advisory due to elevated levels of domoic acid in Monterey Bay. This advisory warns consumers not to eat recreationally harvested mussels and clams, commercially or recreationally caught anchovy and sardines, or the internal organs of commercially or recreationally caught crab taken from Monterey and Santa Cruz counties.  

 

Dangerous levels of domoic acid, which can lead to Amnesic shellfish poisoning if ingested, have been detected in some of these species and are also likely to be present in the other species. Molluscan bivalve shellfish, anchovy and sardines are especially of concern because the toxin resides in their digestive tract and these seafood products are normally not eviscerated prior to consumption.

 

CDPH is continuing to collect a variety of molluscan bivalve shellfish, fin fish and crab samples from the area to monitor the level of domoic acid.
