The essential workers supplying housebound Americans with beef, pork and poultry during the coronavirus pandemic are getting sick and even dying as the virus spreads through plants and communities.

A Smithfield pork processing plant in Sioux Falls, South Dakota, has become the site of the worst coronavirus outbreak in the U.S., with more than 600 confirmed cases in a workforce of 3,700. But the facility is not alone in having a dangerous number of infections:

• At least four workers from a JBS meatpacking plant in Greeley, Colorado, have died of COVID-19 and more than 100 have been infected. JBS has shuttered the plant for now. A union representing the workers has called it an intolerable situation for our members .
• On Wednesday, Colorado Public Radio reported the death of another Colorado meatpacking worker, from a Cargill plant in Fort Morgan. The plant has at least 15 confirmed cases .
• More than 160 workers at a Cargill plant in Hazleton, Pennsylvania, have tested positive for the virus, out of a workforce of around 900.
• Seventy miles away in Souderton, at least 17 workers at a JBS plant have tested positive as well, and one has died . Two additional Pennsylvania plants had to close.
• Two employees at a Tyson Foods pork plant in Columbus Junction, Iowa, died after an outbreak at the facility , which was shuttered on April 6. More than 140 workers there have tested positive.
• Three workers from a Tyson Foods poultry plant in Camilla, Georgia, had died as of last week.
• At least 28 workers at a Tyson beef plant near Pasco, Washington, have tested positive for the virus.
• Wayne Farms, one of the largest poultry producers in the U.S., has had COVID-19 cases at nearly half of its 11 processing facilities . The company declined to say how many workers in total had tested positive.
• Smithfield said Wednesday that it would temporarily close two more plants , in Cudahy, Wisconsin, and Martin City, Missouri, after employees tested positive for COVID-19 at each facility.

The spread of the coronavirus has clearly made a hazardous job even more dangerous.

Laborers at poultry and meat processing plants tend to work right alongside one another, at a time when public health experts advise everyone to stay at least six feet apart . An employee at a poultry plant in Texas that has already recorded multiple COVID-19 cases recently told HuffPost that she and her colleagues were working shoulder to shoulder just like before the pandemic.

Employees in many plants are predominantly people of color or immigrants, doing hard labor for low pay. The average wage for a worker who cuts or trims meat or poultry was $13.36 per hour in 2018, according to the Bureau of Labor Statistics. Workers report a much higher injury rate than the rest of the private sector, and advocates say the hazards are almost certainly worse than the numbers suggest .
