Investigation of outbreaks of COVID-19 in packing and processing plants has revealed that workers infected in carpools and company shuttles.  This observation was originally made by the Canadian Food Safety Agency while investigating an outbreak in an Olymel hog plant that has since re-opened.

Joint CDC and OSHA recommendations emphasize the need for social distancing.  The agencies recommend

• Limiting the number of people in each vehicle
• Enforcing hand sanitation before entering the vehicle and when arriving at the destination
• Wearing cloth masks during transit
• Cleaning and disinfecting seats and surfaces that may be touched

Additional recommendations have been made for common areas including break-rooms, locker and change-rooms, entrances and exits, clock-in locations and bathrooms.
