Swine Production Biosecurity

Four Stage Terminal Biosecurity Programme

The standard terminal biosecurity programme comprises of four specific stages, to be used at the end of each batch following the removal of the pigs.  The objective is simple – to prevent the “carry-over” of pathogenic organisms, thus ensuring that each new batch gets a completely clean, fresh start.  This programme can involve a single room, a building or the whole site.  It can also be used in continuous production farms, either by moving animals around to create space or by using a production break.

Stage 1: Removal of Equipment and Dry Cleaning

  1. Once the pigs have been removed from the building, remove any removable floor slats, feed hoppers, pen separators, tools and all other movable equipment.
  2. Brush loose debris from ceilings, walls and floors and remove all dung, bedding and unused feed, ensuring the building is as clean as possible. Vacuum dust from ledges where practicable and drain slurry.
  3. Thoroughly dry clean all equipment removed from the building.
  4. Load all organic waste onto a lorry ensuring that all outside areas such as concrete pads by doors are cleared of any spilt dung, bedding, refuse etc.  Make sure that the load is covered before transporting from site.
  5. Blow or wash down bulk feed bins before disinfecting.

Stage 2: Water System Clean and Disinfect

  1. Isolate header tanks at mains inlet point, check that they are free from debris and then drain the entire system from the drinker points farthest away.
  2. Clean gross soiling or debris from the tanks as required.
  3. Refill the tank with the necessary volume of water to fill the entire drinking water system adding the appropriate amount of DuPont disinfectant concentrate to achieve the required dilution.
  4. Allow disinfectant solution to fill the system to the drinker points farthest away from the header tank. Leave for one hour.
  5. Thoroughly flush lines through with clean water.  Repeat process if scale and biofilms remain.
  6. Refill the header tank with clean fresh water.

Stage 3: Cleaning Buildings and Equipment

Thorough washing of all surfaces and equipment is essential to achieve the best results from the subsequent disinfection stage.

  1. Soak all surfaces thoroughly with DuPont heavy-duty detergent solution applied at low pressure. Ensure coverage of any air ventilation systems, partitions, feeders, drinkers and all other equipment, including any removed from the building.  Include any service/utility rooms within this procedure.  Leave for 20-30 minutes, and then rinse all surfaces and equipment with clean water at high pressure.
  2. Externally, spray air inlets and built-up deposits from around ventilation boxes and loading areas. Also ensure that all dirty areas such as concrete aprons around the houses and bulk bin pads are washed clean.
  3. Ensure all surfaces and equipment are visibly clean before moving on to the disinfection stage.
  4. Upon completion of the cleaning process, close all doors and place disinfectant footdips at all entrances.

Stage 4: Disinfection

The level of disease-causing organisms present after the cleaning stage usually remains high enough to present a serious disease challenge to a new batch of pigs.   Using a broad spectrum DuPont disinfectant proven effective against viruses, bacteria, fungi and moulds is essential

  1. Use either a knapsack sprayer or pressure washer on a low pressure setting (300psi) to disinfect all equipment removed from the building.
  2. Place the equipment back in the cleaned building prior to disinfecting the house itself.
  3. Using a pressure washer on a low pressure setting (300psi) or an orchard sprayer for larger premises apply the disinfectant solution evenly to all washed internal surfaces to achieve thorough wetting.
  4. Pay particular attention to ledges, corners, cracks and seams ensuring that all sides of supporting posts are covered.
  5. Spray into the apex of the roof and work down the walls to the floors.
  6. Working from one end of the building to the other, apply disinfectant solution to the floor of the house.
  7. To control organisms introduced to the house during the setting up procedure and to disinfect the air and other inaccessible areas of the building use either a fine mist sprayer or thermal fogging machine to apply the DuPont disinfectant solution throughout the building.
