Health officials on Saturday closed local beaches after 50,000 gallons of sewage spilled into the Los Cerritos Channel.

The spill was caused by a pump station malfunction from the Los Angeles County sewer system after it lost power on Saturday, health officials said.

Long Beach City Health Officer Dr. Anissa Davis ordered the closures of coastal swimming areas in Long Beach to while tests are conducted on the water to determine if it’s safe. It was not immediately clear how long the closures would last.

All 7 miles of the city’s beaches were closed.
