After sickening at least 430 people with Salmonella over several months and not being shut down, but then having a plant shut down because of cockroaches in central California, Foster Farms resumed operations

The Centers for Disease Control and Prevention announced last Thursday that the outbreak, which started in March last year, was over.

The USDA threatened to shut the three plants in October over the outbreak. According to Lynne Terry of The Oregonian, who has followed the story since the beginning, when Foster Farms promised to enact tougher food safety procedures, the agency backed down.

Foster Farms issued soundbites instead of data on Wednesday, saying it has ensured that the “most effective treatment protocols” are in place at Livingston plant. It did not release any details about what it’s done to clean up the facility.
