Six restaurants in the San Fernando Valley were closed between May 27 and June 2 due to a public health hazard.

The food facilities had their health permit suspended for cockroach infestations according to a report from the Los Angeles County Public Health Department.

Food facilities 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.

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 venues that were closed. The grade and points listed were on the day they were closed.
