National Biosecurity Standard for Livestock, Poultry and Deadstock Transportation
2.0 Transportation of livestock and poultry
This section will focus on biosecurity best practices when transporting live animals. Everyone involved in the transportation of animals or arranging for their transport shares in the responsibility of ensuring the well-being and safety of animals throughout the entire transportation cycle.
2.1 Routine biosecurity measures
The biosecurity measures that are appropriate for a given transportation event should reflect the:
- disease risks associated with transporting animals from or to particular areas or establishments;
- transporters' roles during the transportation phases; and
- logistics, including the availability of biosecurity infrastructure.
The baseline level of biosecurity that's implemented for every transportation event, even in the absence of a client specifying the need for biosecurity, is referred to as the routine biosecurity measures. Routine biosecurity measures are based on basic biosecurity principles. A few examples of basic biosecurity practices are:
- loading animals in clean trailers using clean equipment
- minimizing cross-contamination between trailers and unloading sites or vice versa
- minimizing cross-contamination from clothes and footwear.
Due to variations within the country and between the various commodity groups, it is impractical to define the routine biosecurity measures that would apply to all commodity groups in Canada. It is recommended that transporters refer to the biosecurity best practices in this document and work with industry associations, provincial representatives and veterinarians to establish routine biosecurity measures that are adapted to their specific risks and challenges.
Once routine biosecurity measures are established, transporters are encouraged to share them with their clients and to work with them to ensure that their biosecurity requirements are met. For more information on identifying the client's biosecurity requirements, see section 2.4.1.
2.2 Enhanced biosecurity measures
In situations where disease is suspected or has been identified and there is an increase in risk, then enhanced biosecurity measures are required to prevent disease spread and possibly eradicate the disease from an area. Again, transporters are encouraged to refer to the biosecurity best practices in this document and work with industry associations, provincial governments and veterinarians to establish enhanced biosecurity measures that will address the disease transmission risks.
Examples of enhanced biosecurity measures include:
- designated transport units, equipment and wash facilities for the transportation of diseased animals;
- designated routes that avoid agriculturally dense areas and/or susceptible animal populations;
- specific cleaning and disinfection protocols; and,
- manure and bedding management:
- designated scrape-out locations for conveyances that have transported diseased animals; may be restricted to specific locations that have manure management systems; and
- restrictions for use of the contaminated bedding for other agricultural purposes, such as spreading on fields for fertilizer.
In the event of a reportable, notifiable or disease of economic significance, industry, provincial and/or federal governments will provide specific biosecurity measures for drivers. Biosecurity measures may include movement restrictions and permits.
2.3 Cycle of transportation phases and related activities
The transportation of livestock and poultry is a continuum of activities starting with the completion of one transportation event to the planning and preparing for the next transportation event. For the purposes of this document, this continuum of activities has been described in four separate phases (see Figure 3):
- between loads phase,
- loading phase,
- on the road phase, and
- unloading phase
2.4 Between loads phase
The Between Loads Phase of transportation encompasses the following activities:
- identifying the customer's biosecurity requirements;
- cleaning and disinfection, which includes:
- removal of organic matter; and
- the inactivation of pathogens
- planning and preparing for the transportation event.
2.4.1 Customer's biosecurity requirements
Customers may have biosecurity requirements specific to their risk tolerance, animal production type and business model. These requirements are often in addition to the transporter's routine biosecurity measures. The customer's biosecurity requirements may include but are not limited to:
- use of a transport unit that is designated to transport a specific type of animal with a specified health status;
- a timeframe of non-use (commonly referred to as downtime) after cleaning and disinfecting the trailer;
- the identification of specific truck wash stations to be used;
- the use of specific cleaning and disinfection protocols, including:
- third party validation of cleaning and disinfection;
- provision of a transport unit wash report (see Annex 1: Transport unit wash report);
- specifying the driver's involvement in loading and unloading;
- specifying where to park on the premises and the route, including the driver's stops, and rest stations; and,
- scrape-out location.
A trip information sheet is a tool commonly used by transport companies to communicate customer biosecurity requirements to the driver. A template and an example of a customer's additional biosecurity requirements has been provided in Annex 2a: Trip information sheet and Annex 2b: Trip information sheet example, respectively.
The early identification of the customer's biosecurity requirements allows drivers to ensure that they have the required biosecurity supplies, documentation and equipment for the transportation event.
Biosecurity best practice
- Implement routine biosecurity measures at all times.
- Identify the customer's biosecurity expectations early in the planning phase.
Encourage the uptake and implementation of biosecurity within industry by practicing routine biosecurity measures at all times, even in situations where the customer has not identified any biosecurity requirements. For assistance, refer to the following sections in this document: Why is biosecurity important to your customer (section 1.2) and the Significance of transport (section 1.3).
2.4.2 Cleaning and disinfection
This section describes:
- biosecurity principles for cleaning and disinfection
- biosecurity considerations when choosing a wash station
- storage of transportation units following cleaning and disinfection
- record-keeping for cleaning and disinfection
Biosecurity best practice
- Perform the cleaning and disinfection steps necessary to optimize the reduction or inactivation of pathogens to reduce the risk to an acceptable level.
Protocols and best practices may not apply to all transportation events and are not directly transferrable between the transportation of different classes of animals or within operations that transport multiple species of livestock and poultry. It is recommended that drivers and transport companies consult specialistsFootnote 5 to develop cleaning and disinfection protocols that are specific to the transport unit and the species of animal that is transported.
This section will focus on the general biosecurity principles for cleaning and disinfection. Biosecurity best practices for cleaning and disinfection, as well as cleaning and disinfection example protocols have been provided in the annexes, see:
- Annex 3: Biosecurity best practices for cleaning and disinfection
- Annex 4a: Example of a wash bay protocol for livestock transport units
- Annex 4b: Example of a truck and crate cleaning and disinfection standard operating procedure in a slaughterhouse
- Annex 4c: Example of a cleaning and disinfection protocol for equine trailers at a wash station
188.8.131.52 Biosecurity principles for cleaning and disinfection
Biosecurity protocols may not include all of the cleaning and disinfection steps identified below – ultimately the combination of steps and frequency will be based on the level of risk. The level of risk varies considerably based on a number of factors, such as type and nature of the pathogen(s), species, herd or flock health status. To illustrate the progressive effectiveness of combining process steps, a percentage of pathogen load reduction for each step has been provided. The percentage is based on extrapolated data from existing reference materialFootnote 6.
Removal of organic matter
- Cleaning – involves a dry phase to remove the organic matter (primarily bedding and manure) commonly referred to as "scrape-out", and a wet phase involving a high volume of clean water to flush out organic matter that remains after scraping out. Pressure washing is not recommended to remove the organic matter during the cleaning phase as it tends to scatter the organic matter within the transport unit rather than flush it out. Proper attention to dry cleaning will make the washing step much easier. The combined effort of dry and wet cleaning could result in a seventy-five percent (75%) reduction in pathogen load.
- Washing – involves the application of a solution of clean water and detergent or degreaser at low pressure to disrupt biofilms and loosen organic material on surfaces. After the organic material is thoroughly saturated, continue washing using a low to medium pressure spray of water to dislodge or loosen the biofilm and organic matter; mechanically scrubbing or scraping surfaces with brushes, brooms or scrapers may be required. The effluent (detergent and biofilm) is then removed from the unit using clean water.
Washing is not complete until organic matter has been completely removed from all surfaces. It may be necessary to wash the transport unit several times to remove organic matter. Removal of organic material and detergent residues is important to ensure chemical disinfectants are not inactivated during the disinfection step. Removing all organic matter and using detergent to wash a transport unit has been shown to result in an 80% reduction in pathogen load.
- Visual inspection of all surfaces is completed to ensure that all organic matter has been removed. This is best done when rinsed water is drained away. See Annex 5a: General visual inspection checklist and 5b: Example of a visual inspection form used for swine transport units.
Inactivation of pathogens
Disinfection, drying (natural or thermal assisted) and baking are steps that help to inactivate pathogens.
- Disinfection – most commonly this involves the application of a chemical at a specific concentration for an identified time period. The type of disinfectant will depend on the pathogens of concern. The concentration will depend on the objective of this step. Some of the disinfectants at lower concentrations can be used for cleaning, while a higher concentration is needed to achieve disinfection. Surfaces must be visibly clean, without pooled water and dry (if possible) prior to applying a disinfectant and the disinfectant must stay wet and fully cover the surface for a specific amount of time to achieve the desired pathogen inactivation or reduction. As temperatures drop below 10°C many chemical disinfectants require an increased contact time and concentration to achieve effective disinfection. As temperatures approach 0°C, cleaning and disinfection should be performed in a heated building or using antifreeze agent. Review disinfectant labels, follow the manufacturer's directions and contact the manufacturer if guidance is required. Disinfectants may be applied by different applications (e.g. spraying or foaming). When used properly, applying a disinfectant has been shown to reduce the pathogen load by over 99%.
- Drying involves natural drying or using thermal assisted processes to ensure that all moisture has evaporated from the transport unit. This additional step ensures that pathogens that may have escaped contact with the disinfectant and that are susceptible to desiccation are inactivated.
- Baking, a thermal process used to inactivate pathogens, may be recommended for some pathogens that escape contact with the disinfectant and require high temperatures to be inactivated. It is acknowledged that there are few facilities with this capability in Canada.
Cleaning and disinfection protocols may involve a combination of the disinfection, drying or baking steps for the inactivation of pathogens. The nature of the pathogen, condition of the transport unit, customer's biosecurity requirements and lack of scientific evidence are just some of the reasons that other inactivation steps, in addition to disinfection, may be required. For example, other inactivation methods, such as thermal assisted drying or baking are recommended when:
- damaged equipment (e.g. damaged or frayed rubber matting or docking bumpers) or the design of the trailer or compartment (e.g. open tubing or gaps) prevents surfaces from coming into contact with the disinfectant;.
- conditions do not allow the disinfectant to be applied in accordance with the manufacturer's directions.
184.108.40.206 Biosecurity considerations when choosing a wash station
It is recognized that biosecurity infrastructure, wash station capacity and cleaning and disinfection protocols vary between wash stations. When feasible, incorporate biosecurity criteria when selecting a wash station to ensure that the wash station:
- can achieve the required level of cleaning and disinfection of the transport unit and associated equipment;
- has identified routes for the site that respect segregation of clean transport units from contaminated units in dirty areas; and,
- has protocols in place that minimize the risk of cross-contamination between transport units.
For detailed guidance refer to Annex 6: Biosecurity guidance for choosing a wash station.
Biosecurity best practice
- Incorporate biosecurity criteria when selecting a wash station.
- Choose a wash station that has the infrastructure and capacity to achieve the required level of cleaning and disinfection.
- Choose a wash station that is designed, organized and maintained in a way that ensures that there is no cross-contamination.
The implementation of biosecurity best practices at wash facilities contributes to:
- increasing drivers' capacity to meet their customer's biosecurity requirements;
- minimizing the risk of the wash station being the source of, or contributing to, contamination of the transport unit; and
- the capacity of industry and provincial and federal governments to mitigate the risk of introduction and spread of disease, which assists in the control and eradication of diseases.
220.127.116.11 Storage of transportation units following cleaning and disinfection
Once a transport unit has been cleaned and disinfected it is important to keep it clean prior to loading. Ideally, transport units should be stored in an area that is:
- physically and functionally separate from transport units that have not been cleaned or disinfected.
- away from pets, farm animals, rodents and wildlife.
- away from people, contaminated equipment, feed and bedding.
- away from exhaust fans and dusty areas.
Biosecurity best practice
- Keep transport units clean prior to loading.
18.104.22.168 Record-keeping for cleaning and disinfection
Drivers, transporter companies and wash facilities should maintain up-to-date records for cleaning and disinfection of the transport unit. Good record-keeping and written protocols provide the ability to evaluate, verify and modify biosecurity programs for transportation events over time. See Annex 1 for an example of a transport unit wash report.
2.4.3 Planning and preparing for the transportation event
Factors that will influence the preparation required for the transportation event include:
- number of loading and unloading sites;
- driver's involvement in loading and unloading animals;
- location for scrape-out;
- driver stops, which may include:
- weigh stations;
- gas stations;
- restaurants; and
- border crossings.
22.214.171.124 Multiple loading sites
From a biosecurity perspective, the ideal transport event includes a single loading and unloading site since the risk of disease contamination and spread increases significantly with each loading and unloading event. It is recognized that this is not always practical or economical. Regardless, drivers and customers should both be aware of the risks and the biosecurity best practices that mitigate the risks associated with multiple loading and unloading sites.
Physically separating animals within the transport unit does not adequately mitigate the risk of infectious disease spread between animals within a trailer. For this reason, the contamination status of the transport unit is reflected by the lowest health status of the animals loaded into the trailer. For multi-loading and unloading sites, the biosecurity best practice is to only load animals that have an equivalent health status.
Biosecurity best practice
- Only load animals that have an equivalent health status.
- Always travel from sites with a higher health status to those with a lower health status
In addition, the risk that the driver and transport unit may become contaminated increases with each loading and unloading event. This in turn increases the risk that the transporter might spread disease at loading and unloading sites. Always travel from sites with a higher health status to those with a lower status. Note that this biosecurity best practice alone offers limited protection. Diseased animals don't always show signs of disease, and customers may not always know or share the disease status of their animals with the driver.
The driver's vigilance in employing the biosecurity best practices throughout the transportation event is crucial in helping prevent disease spread. With the increasing complexity of logistics, likewise there is an increase in the complexity of the biosecurity measures required.
126.96.36.199 Obtain biosecurity equipment and supplies
The amount and type of biosecurity equipment required for a particular transportation event is dependent on the following:
- The number of loading and unloading sites.
- The amount of interaction that the driver will have with the animals, equipment and staff at the loading and unloading sites.
In all cases, it is recommended that the biosecurity equipment contain the supplies required to either clean and disinfect footwear between sites or include at least one pair of footwear (or disposable boot covers – as personal safety considerations allow) and gloves for each loading and unloading site. In situations where the driver will be involved in the loading and handling of animals, the recommendation is that the biosecurity kit include (see Figure 4):
- clean footwear designated to the power unit;
- rubber boots that can be cleaned and disinfected;
- new, freshly laundered cloth or disposable coveralls;
- large disposable garbage bags to store used dirty clothing and other reusable items that need to be laundered and cleaned;
- disinfectant and hand sanitizer;
- paper towel; and
- water and wash bucket.
Ensure that the equipment required for the transportation event is either new or has been cleaned and disinfected. Additional equipment may include:
- animal handling equipment such as poultry gates and nets, rattle paddles, shakers and chase boards;
- a shovel for scraping out the trailer following the transportation event; and
- equipment required to secure the load.
Prevent contamination of your equipment by storing clean equipment in a clean location on your transport unit (for example, a tote or plastic bag that can be closed and kept separate from dirty equipment).
188.8.131.52 Documentation related to biosecurity for a transport event
The documentation requirements for any given transportation event will vary depending on the type of movement and the customer's requirements. From a biosecurity perspective, electronic document exchange is preferred over providing customers with hard copies. When hard copies of documents are required they should always be stored in a clean location.
Exports, imports and interprovincial transportation events may require specific documentation and in some situations, the documentation must accompany the load. Examples of the type of documentation required for these types of movements include; import permits, permits to transport or move, animals transfer documents, animal health records and/or export certificates. Ensure that the required documentation has been obtained prior to leaving.
The driver/transporter should have all the relevant documents readily available during transportation. It may include following:
- transport unit wash report (see the example provided in Annex 1: Transport unit wash report)
- trip information sheet (see Annex 2a: Trip information sheet template and Annex 2b: Trip information sheet example)
- verification and validation of wash protocol
- visual inspection after washing (see Annex 5a: General visual inspection checklist and Annex 5b: Example of a visual inspection form used for swine transport units)
Additional documentation that the driver might have to provide includes:
- veterinary certification;
- animal identification (e.g. a tag, tattoo or chip) to allow animal traceability to the premises of departure and, where possible, to the premises of origin;
- details of any animal's condition that may be a risk (e.g. history of disease, stage of pregnancy);
- documentation of the period of location, period of rest, access to water and feed while on the road; and, disclosure of transport history. The following documentation templates are available in:
- Annex 7a: Disclosure of transport history
- Annex 7b: Transport unit travel history
184.108.40.206 Obtain bedding and feed
Bedding can be obtained prior to leaving for the transportation event or at the loading site. Bedding and feed can transport pests such as the cereal leaf beetle. Prior to loading bedding or feed into the transportation unit, ensure that it is clean, free of contaminants and that it is not a risk of introducing plant pests to another area or region. It is recommended that bedding and feed be obtained from a reputable commercial supplier.
Obtain confirmation from the supplier that validates the bedding or feed is dry, free of wildlife droppings and feathers, and was stored in an appropriate pest monitored location.
Cereal leaf beetle
The risk of spreading cereal leaf beetle to western Canada during efforts to provide feed from eastern Canada to animals during the drought in 2004 was significant. The potential introduction of cereal leaf beetle to western Canada threatened trade with the USA of an estimated $500 million in cereal crops annually.
In addition, once obtained from a supplier, it is recommended that bedding be stored in a clean secure area where it does not come into contact with animals (wild animals, rodents, birds or farm animals) and contaminated equipment or personnel.
220.127.116.11 Driver preparation
Drivers can be a source of contamination, especially if they've come into contact with pets, farm animals, wildlife or contaminated equipment. Before leaving for a transportation event, it is recommended that drivers:
- wash and wear freshly laundered clothing;
- wear clean footwear; and
- avoid contact with any animals (including pets) or wildlife.
Do not travel with your personal pets in the power unit. Personal pets are not trained to respect biosecurity requirements; contaminated paws and fur present the same risk as contaminated footwear, hands and clothing.
2.5 Loading phase
The various types of animal containment systems (trailer vs. crates or compartments), as well as the variance in driver involvement in loading, creates challenges in providing biosecurity guidance that will apply to all transport events. It is important to assess the guidance provided and use your judgment to determine whether it applies to a specific transportation event.
The loading phase includes the following activities:
- Accessing the site
- Entering and exiting the power unit
- Preparing the trailer for loading
- Applying the bedding and loading animals
2.5.1 Accessing the site
When accessing the site, always follow the premises biosecurity protocols. Pay attention to instructions (see Figure 6) provided by the customer on how to access the site, where to pick up bedding (if applicable), parking and signing visitors' logs (if applicable).
The customer may request additional biosecurity measures prior to accessing the loading site. Examples may include:
- cleaning and disinfecting the back of the transport unit prior to making contact with the loading site; and
- cleaning and disinfecting wheels and wheel wells.
Encourage customers to maintain access routes that are free of manure and/or mud or snow. Organic matter, potentially infected with pathogens can accumulate on wheels, wheel wells and the undercarriage, if access routes are contaminated and not poorly maintained. In circumstances where there are no biosecurity protocols on site, at a minimum you should:
- avoid roadways or laneways contaminated by manure or organic matter.
- drive slowly to minimize dust, manure and/or mud from contaminating the transport unit.
- park in the area designated for loading.
- Avoid parking by exhaust fans and air inlets (if possible).
Always follow the premises biosecurity protocols when on site.
2.5.2 Entering and exiting the power unit
When entering and exiting the power unit, avoid contaminating the interior via the implementation of biosecurity practices. Pay particular attention to contamination via hands, clothing and footwear. One way to avoid contaminating the interior of the power unit is by wearing clean clothing, having dedicated footwear for the power unit (driving shoes) and by having separate footwear for exiting the power unit. Always wash your hands prior to entering the power unit or use hand sanitizer prior to touching anything in the interior of the power unit. An example of protocol for entering and exiting the power unit and trailer is available in Annex 8.
2.5.3 Preparing the trailer for loading
When preparing the trailer for loading, it is important to minimize the risk of contamination to the interior of the trailer or crates. Consider people, equipment and things required for loading and put in place biosecurity measures to prevent the contamination of the trailer or crates. For example;
- Place crates in a clean area.
- Do not allow potentially contaminated premises or facility staff or equipment to enter the trailer.
- Do not come into contact with animals that are not involved in the transport event.
2.5.4 Entering the trailer
Follow biosecurity best practices when leaving the power unit and entering the trailer to prevent contaminating the inside of the trailer. It is recommended to wear a clean outer layer of clothing, hat, boots and gloves that are dedicated to tasks performed in the trailer. Store clothing, hats, boots and gloves in a clean location (such as a clean tote or bag) to ensure that they do not become contaminated prior to being used.
Clean and sanitize hands prior to entering the trailer and handling animals for loading, as well as prior to re-entering the power unit. Refer to Annex 8 for an example of protocol for entering and exiting the power unit and trailer.
Biosecurity best practice
- When performing tasks in the trailer, wear clean clothing, hat, footwear, gloves and use loading equipment that is dedicated to the trailer.
2.5.5 Applying the bedding and loading animals
Once in the trailer, apply clean bedding to areas where animals will be loaded. If bedding is provided at the loading site, then ensure that the bedding is dry and clean (e.g. free of contaminants or pests, feces and dirt).
- follow onsite biosecurity protocols, including complying with restricted access on entry, such as demarcation at loading zones.
- prevent backward movement of livestock or bedding/manure from transport unit when loading.
- avoid contact with the animals that are not associated with the transportation event.
18.104.22.168 Compromised animals
Transporters have the right to refuse to load any animal they deem is compromised or unfit for transport. For a list of conditions, please refer to Transporting unfit or compromised animals.
Compromised animals can only be transported directly to the nearest suitable place where they can receive care or be humanely killed (does not include an assembly center), and special transport conditions must be applied.
Unfit animals can only be transported to a place to receive veterinary care, following a veterinarian recommendation and special transport conditions must be applied.
If there are concerns with loading a compromised or unfit animal, refer to the humane transportation federal regulations (Part XII of the Health of Animals Regulations), the Interpretive Guidance for Regulated Parties and the species specific codes of practice (see Codes of Practice for the Care and Handling of Farm Animals).
2.5.6 Exiting the trailer and re-entering the power unit after handling animals
The exterior layer of clothing, hands (either exposed hands or gloved), hat and footwear (designated boots or boot covers) will be contaminated after having handled animals during loading. Without biosecurity measures, the power unit becomes a commingling site for any bacteria, virus or fungi that you have been exposed to either by handling an animal or by contact with the environment.
Biosecurity best practice
- After having handled animals during loading, remove the outer layer of clothing, hat, footwear and gloves and sanitize hands prior to re-entering the power unit.
The ideal biosecurity practice prior to re-entering the power unit at the conclusion of loading after having handled animals is to remove the outer layer of clothing, footwear, and gloves. If the articles are disposable, check with the customer and, dispose of them onsite if possible. Otherwise, contain the articles in a sealable container such as a garbage bag or tote, prior to loading them into a compartment of the transport unit. Sanitize hands prior to entering the power unit and sanitize all contact points within the power unit once you've entered. Refer to Annex 8 for example of protocols on exiting and entering the power unit and trailer.
2.6 On the road phase
While on the road, there is a risk of introduction and spread of disease if you park in close proximity to other animals that are carrying disease or if disease has been identified on premises in close proximity to the route you are travelling. It is important to keep records to document the route travelled, stops made and animal rest stations. Biosecurity can play an important role in mitigating the risk of disease when:
- selecting a route;
- stopping; and,
- at commingling sites.
2.6.1 Selecting a route
The sequence of pick up or delivery should take into consideration the risk of disease transmission (for example; animals of high health status should be loaded first as not to arrive at such premises with a contaminated transport unit). Loading animals of lower health status when transporting with a higher health status will reduce the health status of the high health animals and may also put them at risk of disease. Loading young animals with older animals may also create a risk of spreading disease to the young animals since they could be less immunocompetent (i.e. they're more likely to become sick if exposed to pathogens).
Biosecurity best practice
- Avoid agriculturally dense areas and areas where disease has been identified.
Where possible, avoid agriculturally dense areas and avoid areas where a disease has been identified, particularly if the disease has been identified in the same type of animals being transported. Various tools are being developed by industry associations and provincial governments to make the agricultural community aware of high risk areas in the event of a disease outbreak.
Stops can include border crossings, restaurants, gas stations and weigh stations. Stops can be a source of contamination for the driver, transport unit and, if stopped in close proximity to other animals, it could result in the direct transfer of pathogens to the animals being transported. Some commodity sectors have developed specific protocols for various types of stops, for example border crossings (refer to Annex 9: Example of transport boot protocol to follow when entering and exiting the power unit at high-risk stops). The following biosecurity best practices are recommended at all places a driver may stop:
- park as far away as possible from other animal transport units.
- follow biosecurity best practices when entering and exiting the power unit (see section 2.5.2 – Entering and exiting the power unit).
- discourage people from touching or handling the animals being transported.
2.6.3 Rest stations
In some situations, livestock will be unloaded to rest at some point during the transport event. Rest stations can pose a biosecurity risk since these locations may be frequented by animals of unknown health status. In addition, some rest stations have limited capacity and infrastructure to support the implementation of basic biosecurity measures (e.g. no running water, limited effectiveness in cleaning and disinfecting of animal holding areas such as stalls and paddocks).
Plan in advance and consider the site's capacity for mitigating biosecurity risks when choosing rest stations. If possible, identify rest stations that have health status requirements and request information on potential risks such as previous tenants, disease concerns and biosecurity protocols implemented between tenants, including the cleaning and disinfection protocol used in areas where animals will be kept. Ensure that the rest station has a scrape-out site available.
At commingling sites, give biosecurity consideration to other vehicles, access pathways, the ground type and conditions, equipment, other animals and people. At rest stations, follow additional biosecurity practices to those recommended for stops (see section 2.6.2):
- avoid sharing or using communal equipment (such as shovels, buckets for feed or water, pitch forks, ropes) available for use on site, or clean and disinfect equipment prior to use.
- keep animals segregated from animals of unknown or lower disease status.
- unload and keep your animals in an area that has been cleaned and disinfected.
2.7 Unloading phase
The driver is responsible for the animals until they are unloaded at the destination. The following biosecurity best practices, previously identified in the section on loading (see section 2.5), also apply to unloading:
- Accessing the site
- Entering and exiting the power unit
- Entering the trailer
- Exiting the trailer and re-entering the power unit after unloading animals.
- follow onsite biosecurity protocols (refer to unloading biosecurity requirements recorded in Annex 2a: Trip information sheet), including complying with restricted access on entry, such as demarcation at unloading zones.
- prevent backward movement of livestock, bedding and manure back into transport unit when unloading.
For livestock, the driver may need to unload animals that are injured, sick or dead at destination. If specialized equipment is required to remove these animals, attempt to clean and disinfect them as much as possible prior to use in your conveyance.
The perception that biosecurity requirements are not needed for animals being transported to a final life cycle destination, such as a slaughter facility, is short-sighted. The risk of transmitting pathogens associated with the transport event is equivalent to other commingling locations or even higher. The slaughter establishment and equipment has the potential to be a source of contamination for transport units, drivers and equipment that will be used to move healthy animals.
2.7.1 Scraping out at destination
From a biosecurity perspective, the biosecurity best practice includes scraping out at the unloading site because it:
- allows bedding and manure to be removed following unloading;
- eliminates the need for the driver to go to an additional location just to scrape-out.
Cleaning and disinfection following scrape-out is highly recommended since scrape-out locations can serve as important contamination points.
For biosecurity best practices during scrape-out, refer to Annex 3.1 – Scrape-out.
