Smithfield Foods has initiated a project to add 3,600 ft2 to their Sioux Center, IA bacon plant to permit more effective control of COVID-19 among employees. The project will include a cafeteria and entrance hallway that will permit social distancing of the 470 employees in accordance with the Centers for Disease Control and Prevention guidelines.
Although surfaces in the new facility are designed for ease of cleaning, it is emphasized that COVID-19 spreads mainly by the aerosol route, especially in confined spaces with a low rate of air exchange. It is hoped that Smithfield has 
incorporated an effective HVAC system with HEPA filtration and has also considered dry hydrogen peroxide generators to decontaminate air.
Notwithstanding a high standard for the proposed facility and the installations specified, it will be necessary for workers to follow guidelines on masking and social distancing especially in locker rooms. These precautions will be necessary even when an effective COVID vaccine is deployed.
