Poultry Production Biosecurity

Terminal Biosecurity Programme

Four Stage Terminal Biosecurity Programme

The standard terminal biosecurity programme comprises of 4 specific stages, the objective of which is simple – to prevent the “carry-over” of pathogenic organisms, thus ensuring that each new crop gets a completely clean, fresh start.

Stage 1: Removal of Equipment and Dry Cleaning

1. Remove any residual food from the feeder system and silo.
2. Remove all movable equipment.
3. Blow or wash down all surfaces to remove dust from ceilings, water pipes, fan boxes and inlets.
4. Remove all litter from the house using scrapers and blow or brush loose debris from the ceilings and floor.
5. Load litter onto lorry ensuring that all areas such as concrete pads by doors and silos are cleared of old litter, dust etc. Make sure that the load is covered before transporting from site.
6. Blow or wash down bulk feed bins before disinfecting.

Stage 2: Water System Clean and Disinfect

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

WASH

Using a pressure washer apply an appropriate DuPont detergent solution to all surfaces.  Ensure coverage of air inlets, fan boxes, partitions, feeders, drinkers and other equipment, including any removed from the house.  Include any service/utility rooms in this cleaning procedure before rinsing all surfaces and equipment with clean water at high pressure.

PRE-SOAK

1. Externally, spray air inlets and built-up deposits from around fan boxes and loading areas with DuPont detergent solution. Ensure that all dirty areas such as concrete aprons around the houses and bulk bin pads are washed clean.
2. Internally, soak all surfaces thoroughly with DuPont detergent solution applied at low pressure. Leave for 20-30 minutes, and then rinse at high pressure using clean water.

Ensure all surfaces and equipment are visibly clean before moving on to the disinfection stage.

Stage 4: Disinfection

The level of disease-causing organisms present after the cleaning stage is high enough to present a serious disease challenge to a new crop of birds.

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. Place the equipment back in the cleaned building prior to disinfecting the house itself.
2. 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.
3. Pay particular attention to corners, cracks and seams ensuring that all sides of supporting posts are covered.
4. Spray into the apex of the roof and work down the walls to the floors.
5. Working from one end of the building to the other, apply disinfectant solution to the floor of the building.
6. Upon completion of the disinfectant process, close all doors and place disinfectant footdips at all entrances.
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 a suitable DuPont disinfectant solution evenly.
