SAN LUIS OBISPO — The County of San Luis Obispo Public Health Department is urging residents to avoid contact with ocean water during and for at least three days following significant rainstorms, including the recent storm.

Health officials warn that rainstorm runoff can carry high levels of disease-causing organisms — including bacteria, viruses and protozoa — from watersheds and urban areas into the ocean. Exposure to contaminated water may lead to skin, respiratory and intestinal illnesses. Young children, older adults and individuals with weakened immune systems are particularly vulnerable.

Surfers, swimmers and beachgoers are advised to avoid ocean water during this period, especially near creeks, rivers, storm drains and other runoff outlets that discharge into the ocean.
