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

Between April 16 and April 22, health permits were suspended at those facilities for cockroach infestations, sewage discharge and for a lack of working toilets, 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 happen during routine and owner-initiated inspections, complaint investigations and re-inspections.

The department did not provide details about the nature of the cockroach infestations, such as the number of cockroaches and where in the restaurant they were found.

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

Here are the food facilities that were temporarily closed. Unless otherwise noted, the grades listed were given on the same day the restaurants were closed.
