Three restaurants in the San Fernando Valley — including the Sharky’s Mexican Grill in Tarzana — were temporarily closed last week due to major public health hazards.

Between Oct. 23 and Oct. 29, those facilities had their health permits suspended for cockroach infestations, according to a report from the Los Angeles County Public Health Department.

Restaurants and markets whose permits are suspended must close until another inspection determines the problems have been fixed. Closures can occur during routine and owner-initiated inspections, complaint investigations and reinspections.

The department did not provide details about the nature of the cockroach infestations — like the number of cockroaches and where in the facility they were found.

Major health hazards that cause restaurant closures currently only cost facilities four points, so facilities can receive A grades at the time they are shut down. Starting sometime in 2017, the department will begin implementing new point deductions so that cannot occur anymore.

Here are the food facilities that were temporarily closed. Unless otherwise noted, the grades listed for the facilities were received on the same day they were closed.
