New vehicle pre-loading biosecurity risk guide

New vehicles pose a biosecurity risk to Australia; exotic and highly invasive seed species that hitch a ride on new vehicles exported to Australia pose a high biosecurity risk. If biosecurity risks are not minimised by vehicle manufacturers offshore, there may be business impacts including:

• New vehicles held at the wharf for inspection by the Department of Agriculture, Water and the Environment biosecurity officers.
• Increased surveillance for​ all vehicles.
• Wharf congestion; vehicle vessels unable to unload.
• Wharf charges.
• Charges for 100 per cent inspection for the same make and model (for example, when seed contamination is found).
• Charges for decontamination and re-inspection.
• Delays in meeting vehicle delivery orders.

Australia enjoys freedom from many of the world’s most damaging pests and diseases. There are many exotic pests and insects that could hitch a ride to Australia on new vehicles. I​f these pests establish in Australia they could have a detrimental impact on our agricultural and forestry industries, natural environment, food security and economy. Protecting Australia’s biosecurity is a shared responsibility between governments, industry and the community.

As an exporter you are responsible for making sure that all goods for export to Australia meet Australia’s import and biosecurity requirements, including being free of exotic insects and pests. Everyone in the supply and retail chain has a role in recognising and reporting any signs of pest activity in new vehicles. To avoid delays and additional costs to your business make sure you know what the import and biosecurity requirements are before you export your products.

• Be aware of the seed seasons in the country of export.
• Cover the new vehicles during transport from manufacturer to port.
• Work with wharf authorities to ensure port hygiene and remove vegetation that surrounds all wharf areas.
• Implement weed control measures such as mowing and slashing around all new vehicle standing areas.
• Before loading new vehicles onto the vessel, conduct a general walk-around inspection of all new vehicles. Look at all parts of the vehicles from different angles to ensure they are free of biosecurity risk material.
• Remove and replace contaminated or partly detached sticky wheel covers and other protective material, prior to loading.
• Consider setting up a biosecurity team that is responsible for all of the above activities.

Plant material is a high biosecurity risk and consists of living or dead plants or parts of plants. Plant material that you are likely to find includes:

• seeds – dormant or sprouted
• leaves, twigs, branches, sticks, straw, grass
• flowers and flower parts.

Vehicle surfaces are perfect locations for plant material to lodge. Plant material can carry exotic fungal pathogens or, in the case of seeds, be capable of germinating and introducing a pest plant species or a seed borne disease.

Examples of plant material found on new vehicles include:

 

Soil materials pose a high biosecurity risk for Australia and include sand, gravel, stones, and rocks. These soil materials do not pose a biosecurity risk if they are clean and do not contain any organic matter or other biosecurity risk material.

Soil can be present as road splash; if the splash is 2 mm deep or less it is not a biosecurity risk. Soil as a contaminant on new vehicles will be present in larger quantities and can be found on surfaces such as floors, wheel arches and ledges.

Soil can carry fungal, viral and bacterial pathogens that are exotic to Australia.

Examples of soil found on new vehicles include:

 

Animal material poses a high biosecurity risk to Australia and means material from animal origin including:

• nests – birds, rodents
• faeces – birds, rodents
• live animals.

Vehicle surfaces are perfect locations for animal material to lodge. Animal material can carry viral or bacterial pathogens.

Examples of animal material found on new vehicles include:

 

Insects and snails find their way onto new vehicles for a number of reasons including:

• shade
• shelter
• food source
• surface to make a nest
• movement from one place to another.

Examples of insects and snails on new vehicles:

 

The two levels of contamination are:

• spot contamination
• widespread contamination.

Spot contamination

Spot contamination means small amounts of contamination that can be easily and immediately removed.

Examples of spot contamination on new vehicles:

 

Widespread contamination

Widespread contamination means a larger amount of contamination that cannot be easily and immediately removed, or contamination that is found in multiple areas on the vehicle.

Examples of widespread contamination on new vehicles:

 

Some areas of the vehicles are more likely to contain contamination than other areas. The likely contamination points are:

• plastic protective covers
• radiator, grille and air vents
• wheel arches
• window ledges
• under the car
• engine cavity.

As you inspect the vehicle, concentrate on these likely contamination points. (Note: images are indicative only.)

 

Protective coatings (plastic sheeting and painted-on)

All protective coatings should be checked to see if airborne seeds or plant material have stuck to them. After wet weather these seeds can be hard to find as they are small and tend to disappear under water droplets.

The plastic sheets would usually have contamination stuck to the corners where the sheets have not adhered to the paintwork, where the sheets have come away from the paintwork, or where sheets overhang the side of the panel. The painted-on protective coatings can have airborne seeds stuck to part of the coating.

​

Radiator, grille and air vents

The fins on the radiator, the corners of the grill and the air vents at the base of the windscreen are also ideal locations for captured airborne seeds and plant material.

 

Wheel arches

Wheel arches should be checked for soil that has clumped under the wheel arches or has splattered onto the paintwork. This site is favoured by moths to lay their eggs.

Wheel arches should be inspected for airborne seeds that could be caught on the sound proofing under the wheel arch or around any exposed grease on axles. Check the tops of mudguards and around the inside of the wheel arches—especially carpeted wheel arches—in case they have been contaminated.

​

 

Treatment options

If contamination is found, it must be removed before the new vehicle is loaded onto the vessel.

Some vehicle cleaners have adopted the following treatments with success:

• Seed - hand picking the seed off with sticky tape or equivalent.
• Soil – pressure hose.
• Insects/snails – physical removal.
• Insect infestation – fumigation treatment.

When the vehicles arrive in Australia, the Department of Agriculture, Water and the Environment biosecurity officers will conduct surveillance inspections to ensure compliance with Australia’s import requirements.

If the shipment does not meet Australia’s requirements, the Department may:

• conduct further inspections
• take remedial action to address the biosecurity risk.
