Berry Street plant in Springdale, Arkansas. In July 2020, Tyson Foods said it would hire 200 nurses and administrative personnel, and begin administering coronavirus tests at all of its U.S. production facilities, as part of the company's response to the pandemic. Tyson's Chief Executive Noel White said that the company's investment in automation would likely increase in light of the pandemic. In August 2020, at least 10,261 Tyson workers were confirmed to have COVID-19 (out of a workforce of over 120,000). In November 2020 a wrongful-death lawsuit previously filed by the family of a Tyson employee, alleging "willful and wanton disregard" for employees' health and safety with regard to COVID-19, was amended with new allegations that a plant manager had organized a betting pool for supervisor and managers to bet on how many employees would be affected with COVID-19. In November 2020, Tyson suspended multiple top officials and retained the law firm Covington & Burling to conduct an investigation into these allegations. In December 2020, Tyson received the results of the investigation led by former US Attorney General and Covington & Burling partner Eric Holder, and terminated seven of its top managers at the Waterloo, Iowa plant. The Waterloo plant is Tyson's largest pork plant and was the centre of a COVID-19 outbreak that infected more than 1000 Tyson employees, killing six, before spreading into the broader community. Tyson did not publicly disclose the names of those terminated or the detailed findings of the report, but issued a statement saying that those terminated did not represent the company's core values.

Tyson competitors Perdue Farms and Sanderson Farms sued, claiming that Tyson's claim violated truth-in-advertising/labeling standards. Tyson acknowledged using ionophores in chicken feed. Ionophores are used to control coccidiosis, a parasite common in poultry, and the medication is not used in human medicine. A federal judge ordered Tyson to stop making the "raised without antibiotics" claim by May 15, 2008. In June 2008, USDA inspectors discovered that Tyson had also been using gentamicin, an antibiotic, in unhatched eggs. USDA spokespeople stated that Tyson had not disclosed the use of this antibiotic to the agency, and they issued a letter informing Tyson that the "raised without antibiotics" claim was not truthful. A Tyson spokesperson acknowledged that the company uses the antibiotic and stated that
