USDA says three California poultry processing facilities owned by Foster Farms will be allowed to stay open due to "immediate substantive changes to their slaughtering and processing." Sampling by USDA determined the facilities processed chicken that contained Salmonella responsible for 278 illnesses across 18 states. The outbreak has been ongoing since March.

The agency's Food Safety Inpection Service will monitor the facilities closely and continue intensified sampling of Foster Farms products for three months. Ron Foster, president of Foster Farms, released a statement saying the company has been working for two months to add and improve food safety controls.
