Raw chicken and meat patties stored at unsafe temperatures, a clogged floor sink with standing water and dead cockroaches were discovered at Jim’s Burgers in Pico Rivera during an inspection that ultimately led to the restaurant’s permanent closure last month.

Los Angeles County Public Health Department officials said the June 17 decision to revoke the burger restaurant’s health permit was the result of repeated food temperature violations — a major public health threat — but over the course of six prior routine inspections the restaurant at 4549 S. Rosemead Blvd. never had its permit suspended for those problems.

“The Department has worked in earnest with the owners to rectify repeat violations due to unsanitary conditions,” said county health officials in a statement issued less two weeks before revoking the restaurant’s permit.

Despite logging some of the highest health code violations in the county, the restaurant was only closed once for failing to comply with letter grade posting requirements under a system that allows too many facilities to operate with unsafe and unsanitary conditions and misleads the public about what’s actually going on behind kitchen doors, according to a Los Angeles News Group review of 21 months of food facility inspection data.
