- About 3% of workers in over 100 meat processing plants have tested positive for the coronavirus, the Centers for Disease Control and Prevention said.
- The CDC researchers warned that testing limitations could mean that the count is low.
- "The recognized risk to meat and poultry facility operation requires prompt action to decrease risks to workers, preserve facility function, and maintain the food supply," the researchers said.
About 3% of workers in over 100 meat processing plants have tested positive for the coronavirus as work conditions allow the virus to spread rapidly, according to a study released Friday by the Centers for Disease Control and Prevention.
The CDC researchers warned that testing limitations could mean that the count is low, noting that more infected workers were found in plants that tested more broadly for the virus.
"The recognized risk to meat and poultry facility operation requires prompt action to decrease risks to workers, preserve facility function, and maintain the food supply," the researchers said.
The researchers aggregated data from 115 meat and poultry processing plants across 19 states between April 9 and April 27.
Covid-19 has spread more rapidly in meat processing plants than in other settings because of the nature of the job. On production lines, it is difficult to separate workers by 6 feet or more, the researchers said.
The physical work inside the plants makes it difficult for workers to wear masks, the researchers said. They added that some of the surveyed plants have struggled to implement heightened disinfecting protocols.
"Among workers, socioeconomic challenges might contribute to working while feeling ill, particularly if there are management practices such as bonuses that incentivize attendance," the researchers said. "In addition, some employees were incentivized to work while ill as a result of medical leave and disability policies and attendance bonuses that could encourage working while experiencing symptoms."
Representatives of the American Association of Meat Processors did not immediately respond to CNBC's request for comment.
The survey included 130,578 workers in meat processing plants, 4,913 of whom have tested positive for Covid-19, according to the researchers. They said 20 have died of the disease.
Of the states surveyed, Iowa reported the highest percentage of workers who tested positive, with 18.2% testing positive in two plants. South Dakota reported 17.3% at two of the state's plants have tested positive.
Several major meat processing plants have become hotbeds for coronavirus infections in recent weeks, prompting processors to claim there could be an imminent breakdown in the nation's food supply. In response, President Donald Trump earlier this week invoked the Defense Production Act, a law intended for wartime usage, to designate the meatpacking industry as part of the nation's "critical infrastructure."
Unions and worker rights activists have said the move gives plant owners a green light to ignore job safety if it interferes with a plant's ability to stay open and avoid liability if workers get sick or die.
Labor unions have called for the government to strengthen safety measures for workers whose health is critical to the supply chain. The United Food and Commercial Workers union represents about 250,000 food processing and meatpacking workers across the U.S. and Canada.
In an interview with CNBC, UFCW president Marc Perrone said meatpacking workers need high-quality protective gear, such as N95 respirator masks, and plants must be reconfigured to allow 6 feet of social distance in addition to any plexiglass barriers. He said workers must have expanded access to both diagnostic and antibody testing, too.
The CDC researchers recommended "improving physical distancing, hand hygiene, cleaning and disinfection, and medical leave policies, and providing educational materials in languages spoken by workers" for meat processors to protect workers and remain in operation.
