Attached is a guidance document from the CAFE Emergency Operations group on appropriate measures to clean/disinfect facilities.  The focus is on CDC recommendations for cleaning a facility after a suspected/confirmed COVID-19 case.  We hope this will be useful in the event that someone in your lab or on our research farms tests positive for COVID-19.  This is in addition to the previous guidance on how to clean/disinfect commonly shared equipment to prevent the spread of the virus.  

Hope everyone is doing well.


According to the CDC:

Cleaning refers to the removal of dirt and impurities, including germs, from surfaces. Cleaning alone does not kill germs. But by removing the germs, it decreases their number and therefore any risk of spreading infection.

Disinfecting works by using chemicals, for example EPA-registered disinfectants, to kill germs on surfaces. This process does not necessarily clean dirty surfaces or remove germs. But killing germs remaining on a surface after cleaning further reduces any risk of spreading infection.

CDC Guidelines for Cleaning and Disinfection Community Facilities:

  • Guidance on disinfection of facilities after a suspected/confirmed COVID-19 case
  • Guidance for cleaning and disinfection of non-porous and porous surfaces
  • Links to EPA-Registered disinfectants
  • Guidance for disinfection of electronics
  • Core disinfection/cleaning guidance

EPA-approved disinfectants:

Cleaning and Disinfecting Your Building or Facility if Someone is Sick:

  • Close off areas used by the person who is sick.
  • Open outside doors and windows to increase air circulation in the area. Wait 24 hours before you clean or disinfect. If 24 hours is not feasible, wait as long as possible.
  • Clean and disinfect all areas used by the person who is sick, such as offices, bathrooms, common areas, shared electronic equipment like tablets, touch screens, keyboards, remote controls, and ATM machines.
  • If more than 7 days since the person who is sick visited or used the facility, additional cleaning and disinfection is not necessary.
  • Continue routine cleaning and disinfection.
