Six restaurants in the San Fernando Valley were temporarily closed last week due to major public health hazards.

Between Aug. 6 and Aug. 12, those facilities had their health permits suspended for cockroach and fly 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 rodent and fly infestations — like the number of cockroaches or flies and where in the facility they were found.

If a food facility is closed for a cockroach, rodent or fly infestation, sewage problems or for not having any water running through the facility it loses an additional seven points on top of the four points deducted for major health violations. Any time two major health hazards, such as unsafe food temperatures, are observed, the facility loses an additional three points in its inspection score.

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.
