Although President Trump invoked the Defense Production Act to require meatpackers to stay open, the coronavirus pandemic threatens heartland communities’ most vulnerable populations, including low-income workers of meatpacking plants and their extended families.

“They’re afraid of catching the virus. They’re afraid of spreading it to family members. Some of them are afraid of dying,” said the Rev. Jim Callahan, of the Church of St. Mary of Worthington, a city of 13,000 in Minnesota that has attracted immigrants from across the globe to work at the JBS Pork Processing Plant.

“One guy said to me, ‘I risked my life coming here. I never thought something that I can’t see could take me out.’”

In Grand Island, an outbreak linked to a JBS beef plant that is the city’s largest employer spread rapidly across the rural central Nebraska region, killing more than three dozen people. Many of the dead were elderly residents of long-term care facilities who had relatives or friends employed at the plant.

In Waterloo, Iowa, local officials blame Tyson for endangering not only its workers and their relatives but everyone else who leaves home to work or get groceries. They are furious with the state and federal governments for failing to intervene -- and for pushing hard to reopen the plant days after public pressure helped shut it down.

“We were failed by people who put profit margins and greed before people, predominantly brown people, predominantly immigrants, predominantly people who live in lower socioeconomic quarters,” said Jonathan Grieder, a high school social studies teacher who serves on the Waterloo City Council. “This is going to be with us for so long. There are going to be very deep scars in our community.”

Grieder cried as he recounted how one of his former students, 19, lost her father to the coronavirus and has been left to raise two younger siblings. Their mother died of cancer last September.

As the coronavirus spread from the nation’s meatpacking plants to the broader communities where they are located, it burned through a modest duplex in Waterloo, Iowa.

In the downstairs unit lived Jim Orvis, 65, a beloved friend and uncle who worked in the laundry department at the Tyson Foods pork processing facility, the largest employer in Waterloo. Upstairs was Arthur Scott, a 51-year-old father who was getting his life back on track after a prison term for drugs. He worked 25 miles away at the Tyson dog treats factory in Independence, Iowa.

The two men were not well acquainted. But both fell ill and died last month within days of each other from COVID-19 -- casualties of an outbreak linked to the Waterloo plant that spread across the city of 68,000 people. Similar spread is happening in other communities where the economy centers around raising hogs and cattle and processing their meat, including the hot spots of Grand Island, Neb., and Worthington, Minn.

The virus is “devastating everything,” said the Waterloo duplex owner, Jose Garcia, who received notification two days apart from his deceased tenants’ relatives. “These two guys were here last week. Now they are gone. It’s crazy.”

He said it’s possible one of the men infected the other because they shared an entryway, or that they each contracted the virus separately at their workplaces.

CORONAVIRUS: WHAT YOU NEED TO KNOW

Scott told his daughter, Destiny Proctor, 18, that he suspected he became infected at the Tyson pet food factory, which has stayed open under federal guidance classifying the industry as critical infrastructure.

Proctor and her 15-year-old brother were looking forward to living with their dad this summer. Instead, their final talk was a video call from a hospital where he struggled to talk.

“It was so, so sad,” said Proctor, who described her father as funny and caring and frequently sending her cards and gifts. “He told me he couldn’t breathe.”
