(OREGONLIVE) — The U.S. Department of Agriculture warned the public on Monday 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 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.”
