4. Best Management Practices for Farm Biosecurity for Pig Production

4.3 Transport Vehicles onto the Farm

Refers to Standards 2.2.1 and 2.2.2

Ensure that trucks transporting pigs into or out of the farm travel by an approved route, making visits in the correct sequence, have been adequately sanitized and have drivers that are trained to follow the farm loading and unloading protocols.

4.3.1 Transport Route Know that the transport of incoming pigs does not expose them to other contaminated pigs or indirect sources. Use interlining (truck to truck transfer offsite) where there are multiple drops. Example of an interline procedure. Follow highway routes with low hog densities. The sequence of pick up or delivery should minimize contamination: from higher to lower health status, from less to more hog dense areas, and from farrowing units to nursery then finisher sites. Request or have your veterinarian request the source herd's transport policies. Transporters delivering pigs to farms should maintain a Pig Transport Log of route and stops.Example of transportation logistics. Vehicles dedicated to specific types of transport, for example, PRRS negative pigs, are encouraged. Organize gilt or boar deliveries so that the source herd has recently been tested.

4.3.2 Vehicle Sanitation The frequency of vehicle sanitation (wash, disinfect and dry) will depend on the risk of contamination. Exposure to an abattoir or pigs with a lower health status would require full sanitation. Proper protocol for vehicle sanitation must be taught to drivers. Example oneexample two and example three of sanitation procedures are available. Verification of sanitation procedure. Sanitizing the interior of the trailer is as critical as the contact points. A record of sanitation can be maintained in the Pig Transport Log (Truck Log). The effectiveness of sanitation must be measured to understand the risk posed by a vehicle on farm biosecurity. Similarly a record of verification and results can be entered in the log. Example of a truck wash audit procedure. As truck washes can be a source of contamination, identify whichcommercial or farm truck washes may be used and provide clear instructions on how to use them. Risks and biosecurity procedures for trucks and personnel at the abattoirmust be understood by all personnel delivering hogs. Hog slaughter house personnel must develop biosecurity protocols for visitors and truckers in their yard. The Factsheet and pamphlet developed in Quebec can be useful tools to address this.

4.3.3 Vehicle entry into CAZ Use an entry log for vehicles not associated directly with the farm except where a secondary record, such as a feed slip or farm truck log, can be maintained. The protocol for entry may include truck disinfection, including wheels, and driver communication with barn staff before entry. Consider sanitation equipment (disinfectant and hose) at the access point. Automatic sprayers for vehicle disinfection are now used in some farms, particularly poultry. They are only effective if organic material is first removed and spray coverage is adequate.

4.3.4 Load dock procedures Protocol for RAZ boundary transfer of animalsExample 1and example 2 of the entry of animals including loading dock procedures. The video below describes loading procedures. Load outs should be built so that trucks with hogs do not directly contact the building. A protocol for the driver regarding boot and coverall changedisinfection, and surface contact rules is needed. Facilities to prevent the backward movement of pigs when loading pigs must be installed. Allow no contamination of truck material into the barn. A buffer area between the truck contact zone and the barn exit reduces the risk. A load out area or room with positive air pressure is ideal to reduce the risk of shavings or straw coming back into the barn. A protocol for communicating with barn staff at pig entry is needed to assist the driver with remaining biosecure.
