4. Best Management Practices for Farm Biosecurity for Pig Production
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
184.108.40.206 Know that the transport of incoming pigs does not expose them to other contaminated pigs or indirect sources.
220.127.116.11 Use interlining (truck to truck transfer offsite) where there are multiple drops. Example of an interline procedure.
18.104.22.168 Follow highway routes with low hog densities.
22.214.171.124 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.
126.96.36.199 Request or have your veterinarian request the source herd's transport policies.
188.8.131.52 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
184.108.40.206 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.
220.127.116.11 Verification of sanitation procedure. Sanitizing the interior of the trailer is as critical as the contact points.
18.104.22.168 A record of sanitation can be maintained in the Pig Transport Log (Truck Log).
22.214.171.124 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.
126.96.36.199 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.
188.8.131.52 Risks and biosecurity procedures for trucks and personnel at the abattoirmust be understood by all personnel delivering hogs.
184.108.40.206 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
220.127.116.11 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.
18.104.22.168 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
22.214.171.124 Load outs should be built so that trucks with hogs do not directly contact the building.
126.96.36.199 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.
188.8.131.52 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.
