Summary of Best Management Practices
4. Best Management Practices for Farm Biosecurity for Pig Production
4.1 Pig Sourcing – Incoming pigs should be from few suppliers of known and compatible health status and should be housed isolated from your pigs until you are confident of their compatibility.
4.2 Barrier – The Controlled Access Zone (CAZ) is the pig farm yard, including buildings and driveways, where access is limited and rules for entry apply to avoid cross-contamination, for example between workers or rodents contacting contamination on the driveway from the dead stock or feed truck. The Restricted Access Zone (RAZ) is where the pigs are housed and there would be a defined entry protocol. Identify and sketch these.
4.3 Transport of Pigs – 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.
4.4 People Entry – Protocols must be established for entry into the RAZ by staff and by visitors through an entry room. This should include having a shower or at least using the Danish entrance method. In addition, written rules regarding the unidirectional movement through the barn by age sequence or health zones and other rules should be used. A visitor log and training log verifies compliance.
4.5 Meat Products – No fresh meat should be allowed into the RAZ
4.6 Dead Stock Removal - Dead stock removal protocols should include the process of transferring pigs to the temporary storage, maintenance of the storage and, if using a rendering plant, the sanitation protocol for the rendering truck.
4.7 Other Animals – Facilities and procedures must be in place to keep out rodents (rodent proofing of barn and integrated rodent control program), birds (netting), insects (screening), pets and wildlife to minimize the risk of contamination of the CAZ and RAZ.
4.8 Tools, Supplies and Equipment – Protocols must be in place to ensure that tools, supplies and equipment are never introduced when contaminated. They could include, rules regarding previous animal contact, sanitation protocols, unidirectional movement within a system and a fumigation room.
4.9 Feed and Bedding – Store feed and bedding in containers that avoid contamination by animals or insects. Ensure that protocols for bagged feed, bedding and ingredient entry as well as feed and bedding delivery are in place. Movement of delivery vehicles within a system or pyramid must sequenced based on health risk.
4.10 Water Source – Where surface water is used for drinking, contamination from wildlife or other animals must be avoided and the water chlorinated. Water should be tested annually at least.
4.11 Manure Handling – Keep manure from other farms away from your farm and move your farm manure away from the herd. Maintain strict rules for custom haulers.
5. Aerosols – If you are located in an area near other pig farms or pig transport routes, consider a system, such as air filtration, to prevent the contamination of pigs by pathogens entering as aerosols (pathogens on dust and water droplets). Avoid pig dense areas when transporting breeding stock.
6. On Farm Health Management – This section refers to internal biosecurity (keeping diseases under control and from spreading around your farm from sick to healthy animals) and consists of protocols that help control the spread of disease as well as immunization programs making your pigs more resistant to becoming sick.
