He said the county is seeking to get 200 of the tests.

The potential for COVID-19 to spread to food processing plants is highlighted by the case of massive pork plant in Sioux Falls, S.D. The Smithfield Foods facility there recently closed after at least 634 of the 3,700 employees tested positive for the virus. Workers and their advocates say the company failed to communicate the risks of possible exposure and waited too long to adopt safety measures, according to other press accounts.

Foster Farms Vice President of Communications Ira Brill said Friday the company has worked with health and food safety officials and is doing everything it can to keep workers safe.

The plants are sanitized daily and employees are now being checked for temperatures or viral symptoms when entering. Workers already wore masks while handling food and have been encouraged to keep them on during breaks, he said. Partitions were installed in the break rooms to further encourage workers to practice social distancing

The company is not taking any additional steps after the cases were confirmed, Brill said, because of the precautions already put in place.
