RICHLAND, Wash. (AP) — Three Mid-Columbia farms are among those receiving the biggest fines in the state from the Washington state Department of Labor and Industries for serious violations of agriculture regulations to prevent the spread of the coronavirus.

More than 20 farms have been cited for inadequate COVID precautions.

King Fuji Ranch of Mattawa was fined $13,500 after L&I accused workers assigned to different living spaces of interacting with others and not social distancing. The ranch owner has 15 days to appeal.

Agriculture workers should be assigned to work and living groups of up to 15 people and are not supposed to mingle with workers in other groups, according to Washington state COVID-19 safety plans.

Evans Fruit Co. of Sunnyside, Cowiche and Tieton was fined $6,600 after inspections in all three locations found employees were not wearing face masks, taking temperatures or social distancing, according to L&I.

The company is appealing, and an additional inspection is in progress.

Agrilabor of Benton City was fined $5,400 after L&I said it had worker beds that were less than 6 feet apart. Agrilabor has appealed.

While King Fuji Ranch has been issued the largest fine for agriculture coronavirus-related violations to date, an investigation involving workers who died is underway at Gebbers Farm Operations in Bridgeport, state officials said.

Gebbers has been fined $13,200 for workers assigned to different living groups interacting and no barriers in the kitchen, according to L&I. Gebbers has 15 days to appeal.

Inspections efforts increased this year because of the coronavirus, with Washington state L&I performing more agriculture worker safety and health inspections and consultations than nearly any other state in the country, said Anne Soiza, L&I assistant director for the Division of Occupational Safety and Health.
