Housekeeping and Sanitation
COVID-19
 
One of the Food Safety and Modernization Act (FSMA) categories of Current Good Manufacturing Practices (CGMP) is Sanitation.  Sanitation is understood to also mean housekeeping, for the feed industry. 

Facilities must develop procedures and a schedule for disinfecting workplace surfaces.  Many states have issued orders requiring businesses to disinfect surfaces.  Readers are encouraged to check with their state health departments for their current orders and guidelines.  Many of these guidelines incorporate the following Centers for Disease Control (CDC) guidelines. 

CDC CLEANING AND DISINFECTING GUIDELINES
Perform routine environmental cleaning and disinfection:
Routinely clean and disinfect all frequently touched surfaces in the workplace, such as workstations, keyboards, telephones, handrails, and doorknobs.

If surfaces are dirty, they should be cleaned using a detergent or soap and water prior to disinfection.
For disinfection, most common EPA-registered household disinfectants should be effective Refer to List N on the EPA website for EPA-registered disinfectants that have qualified under EPA’s emerging viral pathogens program for use against SARS-CoV-2.
Follow the manufacturer’s instructions for all cleaning and disinfection products (e.g., concentration, application method and contact time, etc.).

Discourage workers from using other workers’ phones, desks, offices, or other work tools and equipment, when possible. If necessary, clean and disinfect them before and after each use
.
Provide disposable wipes so that commonly used surfaces (for example, doorknobs, keyboards, remote controls, desks, other work tools and equipment) can be wiped down by employees before each use. To disinfect, use products that meet EPA’s criteria for use against SARS-Cov-2, the cause of COVID-19, and are appropriate for the surface.

 Perform enhanced cleaning and disinfection after persons suspected/confirmed to have COVID-19 have been in the facility:
If a sick employee is suspected or confirmed to have COVID-19, follow these CDC recommendations:
Close off areas visited by the ill persons. Open outside doors and windows and use ventilating fans to increase air circulation in the area. Wait 24 hours or as long as practical before beginning cleaning and disinfection.

Cleaning staff should clean and disinfect all areas such as offices, bathrooms, common areas, shared electronic equipment (like tablets, touch screens, keyboards, remote controls, and ATM machines) used by the ill persons, focusing especially on frequently touched surfaces.

CLEANING AND DISINFECTING METHODS
Hard (Non-porous) Surfaces
If surfaces are dirty, they should be cleaned using a detergent or soap and water prior to disinfection.
For disinfection, most common EPA-registered household disinfectants should be effective.
Use products that are EPA-approved for use against the virus that causes COVID-19. Follow the manufacturer’s instructions for all cleaning and disinfection products for concentration, application method and contact time, etc.
Additionally, diluted household bleach solutions (at least 1000ppm sodium hypochlorite) can be used if appropriate for the surface. Follow manufacturer’s instructions for application, ensuring a contact time of at least 1 minute, and allowing proper ventilation during and after application. Check to ensure the product is not past its expiration date. Never mix household bleach with ammonia or any other cleanser. Unexpired household bleach will be effective against coronaviruses when properly diluted. Bleach solutions will be effective for disinfection up to 24 hours.
Prepare a bleach solution by mixing:
5 tablespoons (1/3 cup) bleach per gallon of water or
4 teaspoons bleach per quart of water
Soft (Porous) Surfaces
For soft (porous) surfaces such as carpeted floor, rugs, and drapes, remove visible contamination if present and clean with appropriate cleaners indicated for use on these surfaces. After cleaning:

If the items can be laundered, launder items in accordance with the manufacturer’s instructions using the warmest appropriate water setting for the items and then dry items completely. Otherwise, use products that are EPA-approved for use against the virus that causes COVID-19. and that are suitable for porous surfaces

Electronics
For electronics such as tablets, touch screens, keyboards, remote controls, and ATM machines, remove visible contamination if present.

Follow the manufacturer’s instructions for all cleaning and disinfection products.

Consider use of wipeable covers for electronics.

If no manufacturer guidance is available, consider the use of alcohol-based wipes or sprays containing at least 70% alcohol to disinfect touch screens. Dry surfaces thoroughly to avoid pooling of liquids.
 
Linens, Clothing, and Other Items That Go in the Laundry
In order to minimize the possibility of dispersing virus through the air, do not shake dirty laundry.

Wash items as appropriate in accordance with the manufacturer’s instructions. If possible, launder items using the warmest appropriate water setting for the items and dry items completely. Dirty laundry that has been in contact with an ill person can be washed with other people’s items.

Clean and disinfect hampers or other carts for transporting laundry according to guidance above for hard or soft surfaces.
