Cleaning and Disinfection

Production Situations, Safety Issues

Adapted from the FAD PReP/NAHEMS Guidelines: Cleaning and Disinfection (2011)

production situations
Production Situations

FAD PReP/NAHEMS Guidelines: Cleaning and Disinfection - Production & Safety

poultry premises
Poultry Premises

FAD PReP/NAHEMS Guidelines: Cleaning and Disinfection - Production & Safety

  • Multiple areas, varied equipment
    • Housing, nesting boxes
    • Open floor areas
      • Require removal of litter and manure prior to disinfection
    • Egg storage rooms
    • Egg processing equipment
      • Egg belts, flats, buggies, packing machines
    • Curtains
dairy facilities
Dairy Facilities

FAD PReP/NAHEMS Guidelines: Cleaning and Disinfection - Production & Safety

  • Unique challenges include:
    • Milking equipment
      • Milking units, strainers, coolers, bulk tank
    • Milk-film or deposits
  • Must use products labeled for food contact surfaces
  • Seek assistance from dairy manager
swine facilities
Swine Facilities

FAD PReP/NAHEMS Guidelines: Cleaning and Disinfection - Production & Safety

  • Special situations:
    • Farrowing pens, slats, alleys, slurry pits
    • Bars, crates, gates
    • Electrical equipment
  • Clean and disinfect without leaving residual chemicals
  • Avoid phenolicdisinfectants
equine facilities
Equine Facilities

FAD PReP/NAHEMS Guidelines: Cleaning and Disinfection - Production & Safety

  • Environments highly variable
    • Pastures, paddocks, porous materials
  • Must remove organic debris
  • Use products labeled for surfaces
    • Wood, concrete
  • Use exempted pesticide if registered product not available
aquaculture facilities
Aquaculture Facilities

FAD PReP/NAHEMS Guidelines: Cleaning and Disinfection - Production & Safety

  • Special considerations include:
    • Chemical product runoff
    • Disinfection of transport boats, other water equipment
  • Chlorine and iodine, neutralize with sodium thiosulfate
prions
Prions

FAD PReP/NAHEMS Guidelines: Cleaning and Disinfection - Production & Safety

  • Highly resistant
    • Disinfectants, heat, UV, ionizing radiation
    • Physical inactivation
    • Autoclaving
      • 134-138oC for 18 minutes at 30 lb/in2
      • Not practical
    • No products registered/exempted by EPA for agricultural facilities
    • Exemption would be needed
evaluation
Evaluation

FAD PReP/NAHEMS Guidelines: Cleaning and Disinfection - Production & Safety

  • Inspection of a site by experienced personnel
  • All contaminated areas/equipment C&D’d
    • Fixtures/fittings dismantled
    • Disinfectant at proper concentration and contact time
  • Gross debris (manure, bedding) disposed
  • Other items disposed in a biosecure manner
  • Effluent avoids environmental impact
  • Disinfection measures repeated, if necessary
safety issues and precautions
Safety Issues and Precautions

FAD PReP/NAHEMS Guidelines: Cleaning and Disinfection - Production & Safety

chemical hazards
Chemical Hazards

FAD PReP/NAHEMS Guidelines: Cleaning and Disinfection - Production & Safety

Chemical disinfectants have health hazards or risks

All products must be used with care and appropriate PPE

Prepare and store disinfectants as directed

Rinse areas thoroughly before reintroducing animals

physical hazards
Physical Hazards

FAD PReP/NAHEMS Guidelines: Cleaning and Disinfection - Production & Safety

  • Physical hazards may include:
    • Slippery conditions
    • High pressure sprayers
    • Steam or flame
    • Dust
  • More information in the Health and Safety Guidelines
biological hazards
Biological Hazards

FAD PReP/NAHEMS Guidelines: Cleaning and Disinfection - Production & Safety

Zoonotic diseases

C&D conducted in contaminated areas

Sweeping, scraping, blowing may disperse pathogen

Inhale, ingest, direct contact

Avoid exposure with careful C&D measures and PPE

personal protective equipment
Personal Protective Equipment

FAD PReP/NAHEMS Guidelines: Cleaning and Disinfection - Production & Safety

  • Minimum PPE required during C&D procedures
    • Coveralls, boots, gloves
  • Additional PPE includes:
    • Goggles
    • Face shields
    • Respiratory protection
      • Dust masks/respirators
    • Waterproof or chem-resistant suits
hazard communication
Hazard Communication

FAD PReP/NAHEMS Guidelines: Cleaning and Disinfection - Production & Safety

All C&D team members should have a complete orientation covering potential hazards

Complete understanding of specific safety precautions must be obtained before entering premises
