Avila Beach under health advisory
December 5, 2012
Following a heavy rain, health officials warn that bacteria, pathogens, worms and viruses can end up in the ocean and suggest staying out of the water for 72 hours.
SLO Environmental Health Services staff collects ocean water samples at 19 locations along the coast on a weekly basis. Samples are then analyzed for three types of indicator bacteria that may cause human illness.
If state standards are not met, a health advisory is issued.
