Biosecurity:

Poultry Transport Biosecurity
By DuPont Animal Health Systems. The importance of biosecurity for all vehicles associated with poultry production cannot be stressed enough.

Introduction
This applies especially to livestock and feed vehicles, but also to any others visiting poultry premises. Livestock haulage and other vehicles, such as feed lorries, engineers and other visitors unfortunately provide an excellent vector through which disease can spread.

Our unique Transport Biosecurity programme provides poultry farmers and hauliers with step-by-step procedures to follow. If adhered to, these procedures can help reduce disease transmission via transportation of livestock.

Vehicle Disinfection Summary
In addition to livestock haulage vehicles, all vehicles e.g. feed lorries and contractors must follow this summary to reduce the potential for transmission of disease.

Only essential vehicles should enter the site.
All vehicles visiting the unit should be kept outside the biosecurity perimeter if at all possible.
Vehicles should be thoroughly cleaned and disinfected using the DuPont Vehicle Biosecurity Programme prior to arrival at the unit.
Wheels, tyres and wheel arches should be cleaned and disinfected upon arrival at the unit using disinfectant wheel dips or sprays where provided.
Personnel should wear appropriate personal protective equipment (PPE), use disinfectant footdips, and disinfect their hands prior to entering premises.

Vehicle Cleaning and Disinfection Procedures
Before undertaking the following biosecurity programme please ensure that the person carrying out the procedure is wearing clean and disinfected protective waterproof coveralls, Wellington boots, rubber gloves and goggles.

STAGE 1. Dry Cleaning - Removing Organic Soiling
It is essential to remove all gross organic soiling from the vehicle, as dung and refuse contain high levels of contamination and are a major source of infection.

Using brushes and scrapers ensure the following areas are covered:

Once all modules and carrying cages have been removed from the trailer (area where poultry are transported), scrape then brush any soiling/litter from the deck, ensuring all organic material is removed.
Particular attention must be paid to the removal of organic material from the underside of the vehicle where deposits can build up. Using a stiff hand brush (or pressure washer where necessary), ensure that any deposits of mud, litter etc are removed from the wheels, wheel arches, tyres, mud-guards and exposed chassis of the vehicle.
All soiled litter and refuse should be disposed of in accordance with regional local authority or governmental guidelines.

Enclosed Trailer (Box Lorry)
Starting at the top of the vehicle then working down, first scrape out all soiling and refuse, and then brush the floor and any internal surfaces.
Ensure that any gross organic material is removed from the tail lift of the truck where applicable by scraping and brushing.
STAGE 2. Cleaning
Following the removal of the gross organic soiling, high levels of infective material will still remain.

Cleaning with a detergent, such as Neutrafoam™, at a dilution of 1:100 for spraying or 1:50 for foaming will ensure that greasy deposits do not remain on any surfaces. Using a detergent also reduces the time taken to clean by up to 60%, and reduces the spread of disease in washing water.

Apply with either a knapsack sprayer or pressure washer using the appropriate application rate (500ml/m2 for normal application, 250ml/m2 for foam application). If using a pressure washer, ensure that it is set on a low pressure setting (approx. 500 psi :35 bars) using a 45º angle jet.

Cleaning the Vehicle

Using either a pressure washer or knapsack sprayer, starting at the top and working down, soak all internal and external surfaces of the vehicle (excluding the cab interior) with Neutrafoam™ detergent at 1:100 dilution rate.
Ensure that special attention is paid to the wheels, wheel arches, tyres, mud-guards and underside of the vehicle.
Ensure that any equipment stored in the vehicle such as shovel, brush etc are removed and washed thoroughly with Neutrafoam™.
Allow at least 10 minutes for the detergent to penetrate and loosen the dirt from all surfaces before rinsing at high pressure with clean water.
It is essential to have removed all organic material before proceeding to the disinfection stage.

STAGE 3. Disinfection
The level of disease organisms, particularly viruses, present after cleaning and sanitizing could still be high enough to offer a serious disease challenge. The use of a broad spectrum virucidal disinfectant active against viruses, bacteria and fungi must be used to complete this effective disease control programme.

Use Virkon® S at a dilution rate of 1:100 solution (1KG in each 100 litres) and rate of 300 ml/m2 at low pressure:

Outside of vehicle, start at the top and work down each side.
Ensure that special attention is paid to the wheel arches, tyres, mudguards and underside of the vehicle.
Ensure that special attention is paid to the wheel arches, tyres, mudguards and underside of the vehicle.
Attention must be paid to the loading ramp and tail gate lift where applicable.
Ensure that all washed equipment is sprayed or soaked in disinfectant solution.
In very rare instances, Virkon® S may affect untreated metals or inferior or damaged galvanised metals. In these cases we recommend rinsing these areas with clean water after disinfection ensuring a contact time of at least 5 minutes.

Ensure that any modules fitted onto the transporter have been fully cleaned and disinfected using a crate/module washer and are only replaced once the transporter has undergone the DuPont Vehicle Biosecurity Programme.

STAGE 4. Cleansing & Disinfecting the Cab
Remove all removable items from the cab of the vehicle including the floor mats; clothing, Wellington boots etc, and then using a dustpan and brush remove any and dispose of it into a refuse sack. Ensure that the foot pedals are free from any organic material.
Using a soft hand brush and a bucket of Biosolve® Plus at a dilution rate of 1:100, clean the cab floor, floor mats and foot pedals allowing at least 10 minutes for the detergent to penetrate and loosen the dirt before rinsing with clean water.
Using a clean cloth soaked in a solution of Virkon® S at a dilution rate of 1:100, disinfect the cab floor, floor mats and foot pedals.
Ensure that all items packed back into the cab are clean and disinfected, where possible.
Finally
Park the vehicle on a slope to drain and dry.
Once the vehicle is removed from the wash area, wash down the concrete surface with detergent making sure no muck or debris remains.
Wash & disinfect waterproof overalls and boots.
Take care to avoid any solutions entering surface water drains or water courses
