Seasonal Rain Advisory Issued by Environmenteal Health Services

(SANTA BARBARA, Calif.) – With the current rainfall in the forecast, the Santa Barbara County Environmental Health Services Division reminds residents about health issues associated with storm water runoff. Storm water is untreated rain water that flows through the drain system into creeks, the ocean, and other waterways. Contact with storm water may increase the risk for certain types of illnesses such as rashes, fever, chills, ear infections, vomiting, and diarrhea. 

Unlike the municipal sewer system, water carried by a storm drain system is not treated.  To minimize potential health risks, it is recommended that people do not swim, play or surf in the ocean and creeks for at least three days following a rain event.  Beachgoers should also avoid areas near the outfall from drainpipes and creeks that enter the ocean following a rain event as storm water runoff may carry high levels of bacteria and pollutants.  

Sport harvesters should wait at least 10 days after a significant rain to harvest shellfish. High bacterial levels, pesticide, herbicide and motor oil grease flushed into the ocean with the storm runoff may contaminate the shellfish beds.  When raw or undercooked contaminated shellfish is eaten, serious illnesses such as gastroenteritis, septicemia, salmonellosis, and hepatitis may result.  Adequate cooking of shellfish will destroy harmful bacteria, but may not be effective in killing viruses. In addition, cooking does not eliminate chemical and metal pollutants in the shellfish.
