AWR 206-1
Animal Disease Response Training
Scope Statement
This lesson details the requirements for managing
the cleaning and disinfecting (C&D) operations for
an animal disease response including initial site
assessment, required resources, procedures, and
the associated health, safety and biosecurity
challenges.
Animal Disease Response Training
Terminal Learning Objective
Describe appropriate cleaning and disinfecting
(C&D) procedures for people, vehicles, equipment
and property.
Animal Disease Response Training
Enabling Learning Objectives
5-1 Explain the purpose of cleaning and disinfecting.
5-2 Describe the processes of cleaning and
disinfecting of premises and equipment.
5-3 List the safety issues associated with performing
cleaning and disinfecting procedures.
Animal Disease Response Training
Why do we clean and disinfect?
• Prevent spread of infection
• Prevent recurrence of infection
• Process occurs during entire
incident from discovery through
recovery
Animal Disease Response Training
Cleaning and Disinfecting
• Responders may be involved
with cleaning activities on
premises, in buildings, pens
and enclosures.
• Rinseates and runoff should
be contained and disposed of
according to EPA treatment
technologies.
Animal Disease Response Training
What are the basic steps?
• Remove all visible gross
contaminants
• Apply detergent to surface
and allow time to disperse
• Rinse the surface thoroughly
• Apply an EPA registered
disinfectant to inactivate
disease agents
Animal Disease Response Training
Cleaning
• Purpose of cleaning process is to remove all manure, dirt,
and other organic material increasing the effectiveness of
disinfectants
• Four basic steps:
–
–
–
–
Dry cleaning
Wet wash
Rinse
Dry
Animal Disease Response Training
Dry Cleaning
• A shovel or broom should be used to remove all
organic matter such as straw, manure, dirt, dust
or any other large particles
Animal Disease Response Training
Wet Wash
• Efficiency of wet wash depends on:
–
–
–
–
Concentration of cleaning agent
Temperature
Contact time
Hardness of water
Animal Disease Response Training
Rinse
• Residual detergent left
on surfaces will reduce
effectiveness of applied
disinfectants
• Important to use
adequate amount of
water
Animal Disease Response Training
Dry
• A dry surface ensures the disinfectant will adhere and
increases the contact time and efficacy
• Drying time can be reduced by using fans or other
blowing equipment
• Hand drying should be avoided
Animal Disease Response Training
Disinfectants
• Recommended by animal health officials
• Decision will be based upon variety of factors:
–
–
–
–
–
–
–
–
Disease present
Available application methods
Contact time required
Ambient temperature
Water hardness
Organic matter
Health & safety issues
Environmental impact
Animal Disease Response Training
Personnel, Vehicles and Property
• Stations are important in
controlling the cleaning
and disinfecting process
• Vital to the success of
the disease suppression
effort
Animal Disease Response Training
Cleaning and Disinfecting Station
•
•
•
•
Arranged near access and exit points
Easily disinfected and allow for future expansion
Preferably established on hard surfaces
Include a water supply, containment measures and shelter
Animal Disease Response Training
Personnel
• Personnel leaving an infected premises can transport
disease on their clothing, boots, hands, and respiratory
track
• Contamination can occur when:
–
–
–
–
Physical contact with infected animals
Animals are euthanized
Disposing of carcasses
Removing manure, bedding, and debris
Animal Disease Response Training
Multi-Personnel C&D Station
• Similar to conventional
HazMat decontamination line
• Requires a dressed team to
assist personnel leaving the
infected zone
• Best performed by using the
buddy system
Animal Disease Response Training
Contaminated Clothing and Equipment
• Disposable items are placed in heavy gauge plastic bags
• Outside sprayed with disinfectant
• Disposal may include burial or incineration
Animal Disease Response Training
Other Personnel on Site
• Anyone on a premises,
suspected or confirmed
with a disease, must
remain until they
undergo cleaning and
disinfecting procedures.
Animal Disease Response Training
Vehicles
• All vehicles must complete C&D before entering and
leaving a premises
• All hard to reach areas must be addressed:
–
–
–
–
Wheels
Mud flaps
Undercarriage
Foot wells and mats
Animal Disease Response Training
Premises Cleaning and Disinfecting
• After animals have been euthanized and disposed, the
premises must be thoroughly cleaned and disinfected
before restocking of animals.
Animal Disease Response Training
Premises Cleaning
•
•
•
•
Manual removal of bedding, manure, feeders, etc.
Must be cleaned down to original surface
Porous building materials may be destroyed
Capture rinseate water for treatment
Animal Disease Response Training
Premises Disinfection
• Use disease specific EPA
registered disinfectant
• Thoroughly wet surface,
allow proper contact time
• May be repeated a second
time
• If ineffective the first time, a
different contractor may be
used
Animal Disease Response Training
Disease Free Status and Restocking
• Sentinel animals monitored for incubation periods
• Repeated C&D if sentinel animals fall ill
• Restocking only if disease free status has been achieved
Animal Disease Response Training
Accident Cases from an IP or CP
• Human health, life and safety
takes precedence
• If risk of contamination exists,
Incident Command and hospital
authorities must be informed of
disease agent
• Ambulance should remain
outside the infected zone
Animal Disease Response Training
C and D Safety Considerations
•
•
•
•
Electricity
Machinery/vehicles
Enclosed tanks, silos, pits
Disinfectants, detergents,
surfactants, soap
• High pressure sprayers
• Dust
Animal Disease Response Training
C and D Safety Considerations
• Ammonia
• Asbestos
• Walking and working surfaces
• Chemicals and explosive material
– Gasoline, diesel fuel, propane, agricultural chemicals:
• Fertilizer
• Herbicides
• Pesticides
Animal Disease Response Training
Summary
Proper and thorough cleaning and disinfecting
are critical for the containment, control, and
eradication of an animal disease. Responders
must wear PPE appropriate for the task they
are performing to ensure personal safety and
maintain biosecurity procedures.
