The San Francisco Fire Department says inspectors shut down numerous illegal vendors at Fisherman's Wharf Thursday following a safety scare.



No one had major injuries.

"As soon as it exploded, all the other food carts left," said Randall Scott of Fisherman's Wharf Community Benefit District. "They disappeared. It's a big problem."

On Monday, we talked to the CEO of Pier 39 about the illegal vendors. He raised concerns about unrefrigerated food and alcohol being served without ID checks.
