LANSING, MICH. -- Michigan on Monday ordered coronavirus testing of agricultural and migrant workers, citing nearly a dozen outbreaks at farms and food-processing plants in recent weeks.

Under the emergency order issued by the state Department of Health and Human Services, migrant housing camp operators must do initial baseline testing of all residents age 18 and older. New residents must be tested within 48 hours of their arrival, be provided separate housing and get a second test 10 to 14 days after arriving.

Agricultural employers with more than 20 workers on site at a time must also ensure testing — both for current and new employees and any workers with symptoms or suspected exposure to COVID-19. The requirement applies to meat, poultry and egg processing plants; greenhouses; and employers that hire migrant or season workers who do not live on site.

“The men and women who work in our fields and food processing plants are at particular risk for COVID-19, and they need and deserve protection,” Robert Gordon, director of health department, said in a statement. “Today’s order will help to reduce the spread of COVID in communities across Michigan and reduce the pandemic’s disparate impact on Latinos.”

A spokeswoman said department officials were not aware of any other states requiring such universal testing of agricultural and migrant workers.

Gordon cited 11 recent identified outbreaks in farms and food processing plants, and said Latinos are 5 per cent of Michigan’s population but account for 11 per cent of virus cases in which the individual’s ethnicity is identified.

The testing must be implemented as “soon as practicable” and no later than Aug. 24, according to the order. State grants are available to help mitigate testing and other virus costs.
