 Food safety is a factor in hiring employees at the Mount Pleasant facility . Before applying , potential employees must complete a 16 @-@ hour food safety training course through Iowa State University . The class includes written tests which each applicant must pass before completing the course . On the job , employees must don a sealed clean room suit before entering slicing cells . The suits are cleaned and sealed in a clean room laundry facility in North Carolina by the uniform company Cintas . Employees replace the clean suit each time they leave the cell so each employee averages five suits per day .
