Rain Advisory In Effect
The Environmental Health staff advises swimmers that levels of bacteria can rise significantly in ocean and bay waters adjacent to storm drains, creeks and rivers during and after rainstorms. The elevated levels of bacteria can continue for a period of at least 3 days depending upon the intensity of the rain and the volume of the runoff. Swimmers should avoid coastal waters impacted by discharging storm drains, creeks and rivers, and beach users should avoid contact with any runoff on the beach during dry or wet weather conditions.
Shellfish Toxins/ Quarantine Information
The Annual Mussel Quarantine in California is in effect from May 1 through October 31. Consumers can receive updated information by calling the California Department of Health Services "Biotoxin Information Line" at 1-800-553-4133. Sport harvesting of mussels for human consumption is not allowed along the entire California coastline during this period. All bays and inlets are included in the quarantine. The purpose of this quarantine is to protect the public from deadly poisons that may be present in bivalve mollusks, such as mussels, clams, oysters and scallops. Since 1927, California recorded 521 cases of Paralytic Shellfish Poisoning, including 32 deaths.
Mussels are the most dangerous because they accumulate high levels of toxins more quickly than other mollusks and are commonly eaten without removing the digestive organs. All dark meat should be removed from clams, oysters and scallops before eating, since the poison may be concentrated in those areas. Health officials emphasize that toxic mussels cannot be distinguished from harmless ones. Moreover, cooking does not destroy the toxins, as they are heat resistant.
The California quarantine applies only to mussels collected locally by sports harvesters. All commercial shellfish harvesters in California must be certified by the State and are subject to strict testing requirements.
