A troubling new report says many U.S. beaches, including some right here in Southern California, are unsafe for swimming and potentially dangerous.

The findings were released by the Environment America Research and Policy Center on Tuesday.

According to the report, samples were taken at more than 4,500 beaches nationwide.

Nearly 60-percent showed potentially unsafe levels of fecal bacteria on at least one day last year.

The most alarming in California that leads the list is Cabrillo Beach in San Pedro. It had the highest percentage of days with a high bacteria count deemed potentially dangerous.

Researchers found that bacteria counts can spike on certain days, and fecal matter from people or animals is the main offender.

Out of 175 samples taken one section of the beach registered 85 unsafe readings.
