resources - status! USDA primary agency for ag resources! EPA support agency

Agriculture and Natural Agriculture and Natural Resources AnnexResources Annex
! OSC role– Support agency
! provide technical assistance and subject-matter expertise on facility remediation, and agricultural (animal and crop), and contaminated product disposal
! Surge capacity lab! Identify antimicrobial chemicals/pesticides! Investigative support and intelligence analysis for oil/hazmat
incidents! Technical assistance in determining when water is suitable for
human consumption

! OSC role! 3 levels of response! “regardless of response level, the ag
community must be prepared to work closely with the emergency management community to deal with an animal health emergency

DecontaminationDecontamination

2004 OSC Readiness Training Program 11
EPA DefinitionEPA Definition
! The process of eliminating or reducing a contaminant to a level that allows the location or item to be returned to normal use. A contaminant is a chemical, biological, or radiological substance that may occur on surfaces, in water, or in/on food or agricultural commodities that poses a potential risk to human health and/or the environment
2004 OSC Readiness Training Program 12
USDA DefinitionUSDA Definition
! Cleaning and disinfection (C&D) are tools used to impede the spread of pathogenic microorganisms.
! Disinfection is not sterilization! C&D will prevent the movement of
microorganisms on fomites and reduce the risk of pathogen transmission during the period while highly contagious disease pathogens are being eliminated from the national herd
2004 OSC Readiness Training Program 13
CleaningCleaning
! Major part of sanitation procedures. Heavy contamination of animal feces and urine in animal confinement areas and fat in abattoirs
! “High pressure cleaning with hot water and detergents is the only practicable procedure but brings its own attendant problems of the disposal of effluent”
2004 OSC Readiness Training Program 14
DisinfectantDisinfectant
! Physical or chemical agent that destroys vegetative forms of harmful micro-organisms, usually on inanimate objects but sometimes on the coat or hooves of animals.

Function of the C&D UnitFunction of the C&D Unit
! Arrive on premises during euthanasia and disposal and provide C&D for all vehicles, equipment, and personnel leaving the premises– Provide input to the Command level – Provide technical advice to owners of infected or
contiguous premises– Operate and arrange for C&D stations for vehicles– Coordinate with Logistics Section on supply of
disinfectant– Provide personnel to supervise C&D of quarantined
premises
2004 OSC Readiness Training Program 18
Background KnowledgeBackground Knowledge
! Pathogen transmission to susceptible species (including humans if zoonotic) may occur:– Directly, via animal contact with an infeted
animal or animal product, including blood; secretion (e.g., milk and saliva); excretions (e.g., manure and urine); epidermal outgrowths (feathers, hair, horn, hooves); and exhaled moisture
2004 OSC Readiness Training Program 19
pathogen transmission cont.pathogen transmission cont.
– Indirectly, via animal contact with contaminated feed, and water; fomites (e.g., clothing, tools, equipment, vehicles, bedding, supplies, and other inanimate objects); and people or animals (e.g., roaming and scavenging wildlife – including vermin and dogs – on the premises) who are contaminated with a pathogen, but not infected or susceptible to it
2004 OSC Readiness Training Program 20
pathogen transmission cont.pathogen transmission cont.
– Via arthropod vectors (e.g., insects and ticks) that may serve either as mechanical carriers of a disease agent or as an important part of the life cycle of the agent (e.g., mosquitoes that carry the Rift Valley fever agent).
2004 OSC Readiness Training Program 21
Decontamination AgentsDecontamination Agents! Physical
– Heat, radiation, filtration, impact! Chemical
– Soaps/detergents– Phenol and coal tar acids– Biguanides– Halogens– Aldehydes– Surfactants– Alcohols– Heavy metals– Dyes– Gaseous disinfectants

Federal Insecticide, Fungicide, Federal Insecticide, Fungicide, and and RodenticideRodenticide Act (FIFRA)Act (FIFRA)
! Product-licensing statute: pesticide products must either have an EPA registration or exemption before they may be distributed, sold, or used in the U.S.– Review and register pesticides for specified use– Cancel a registration for cause– Issue crisis exemption if needed

! Effective disposal of animal carcasses and materials is a key component of a successful response to an animal health emergency. Overall goal is to control and contain the spread of disease– Disposal personnel– Evaluation of disposal sites– Selection of optimal methods– Disposal of miscellaneous items

Disposal UnitDisposal Unit
! Disposal Unit Leader! Disposal Team Manager! Disposal Team Members
! Team assigned to each premises as soon as possible after it is declared an infected or contact premises
2004 OSC Readiness Training Program 30
Disposal LocationsDisposal Locations
! On-Site Disposal– Most expeditious– Public health or environmental protection laws, permits– Suitability of potential sites on property– Number and species of carcasses– Potential hazard material may pose to humans/livestock
on site– Amount and size of rocks, soil types– Access roads for large trucks– High-water line, water reservoirs, wells
2004 OSC Readiness Training Program 31
OffOff--Site DisposalSite Disposal
! Safe, efficient transfer of carcasses! May be considered when
– Infectious material from labs and on-site facilities are limited
– Insufficient space or poor seasonal conditions on-site– Too close to human habitation– Carcasses can be rendered in off-site facilities more
efficiently than on-site disposal
2004 OSC Readiness Training Program 32
Transporting Infected MaterialTransporting Infected Material! Carcasses must be sprayed with disinfectant prior to
loading! Large-capacity vehicle made leakproof by lining and
sealing with disposable, tough, plastic sheeting ! Layer of absorbent material (sawdust) over plastic! Minimal handling of carcasss! Careful loading! Spray with disinfectant after loading and after sealing! Biosecurity measures entering and leaving premises! Clean vehicle after leaving premises! Clean and disinfect vehicle after unloading carcasses
2004 OSC Readiness Training Program 33
Temporary StorageTemporary Storage
! Prompt disposal after euthanasia may be impossible especially in major outbreak– Pile carcasses in closed building– Pile carcasses outdoors, spray with disinfectant,
cover securely with tarpaulin– Pile carcasses outdoors and cover with soil– Control measure for insects/fomites to reduce
disease spread via humans, domestic pets, wild animals, vermin
