Hillshire Brands Co. officials say they plan to close the company's Florence plant, which employs about 1,100 people.
The company said in a statement that the plant is set to close on Dec. 30.
The Florence plant includes cooking operations for breakfast sandwiches and breakfast sausages.
Tom Hayes, chief supply chain officer, said closing the Florence plant was a "very difficult" decision.
However, he said the company determined that it won't meet efficiency or long-term profit expectations.
Company officials said in the statement that the firm will provide severance and outplacement assistance to employees consistent with its company policies.
