The U.S. Department of Agriculture warned is warning the public about a salmonella outbreak traced to Foster Farms chicken.
The agency said nearly 280 illnesses in 18 states had been traced to raw poultry from three Foster Farms facilities in California.The company said it is not issuing a recall. But the USDA said the suspect packages have one of these establishment numbers — P6137, P6137A or P7632 — inside the USDA mark of inspection.

The chicken was distributed mainly to stores in Oregon, Washington and California. The USDA said most of those sickened live in California.

Foster Farms said in a statement that it had bolstered food safety practices at the three plants in central California.

“We deeply regret any foodborne illness that may be associated with any of our products,” Ron Foster, Foster Farms president said in a statement. “We are committed to ensuring the safety of our products, and our family owned company has maintained an excellent food safety record during its 80-year history.”

Salmonella, like other foodborne bacteria, can cause a range of gastrointestional symptoms, including cramps, diarrhea and fever within eight to 72 hours after consumption. It can also be deadly.

The USDA allows producers to sell raw poultry with a nearly 10 percent incidence rate of salmonella. Foster Farms says it’s always met that standard.
