CDC’s tour, known as an Epi Aid, was conducted on April 14th--after the plant had already halted operations 3 days earlier. The team included veterinary epidemiologists, an epidemic intelligence service officer, an industrial hygienist, and a laboratory leadership service officer. They were tasked with evaluating existing health and safety controls at the Sioux Falls plant, then providing recommendations for improvement. 

Observations made by CDC’s team resulted in roughly 10 pages of recommendations covering a long list of areas—social distancing, screening, sick leave, hand hygiene, sanitation, training, communication, personal protective equipment, and more.

CDC also requested additional information centered around key demographics and workstation information from the Smithfield plant based on two inconclusive observations:

• Our team was unable to identify important demographic information about this workforce, limiting our ability to understand the diversity of the employees. However, plant management reported that there were approximately 40 different languages spoken by employees in the plant and that English, Spanish, Kunama, Swahili, Nepali, Tigrinya, Amharic, French, Oromo, and Vietnamese are the top 10 languages.
• We were also unable to obtain information about the workstations of confirmed positive cases. This type of information could provide a better understanding of what workplace factors may have contributed to the spread of COVID-19 among employees.

CDC says the recommendations are steps that Smithfield Foods may want to consider implementing to address the conditions identified at the plant. The recommendations are discretionary and not required or mandated by CDC.
