5. Aerosols

Refers to Standard 2.2.5

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)

5.1 Risk due to aerosol transmission

5.1.1.1 Understand your risk of contamination by aerosol for important diseases such as PRRS virus, Influenza virus or Mycoplasma hyopneumoniae. Multipliers and studs consider less than 5 km to the next pig farm or pig transport route a risk. Factors such as humidity, obstacles such as hills and prevailing winds also have an influence.

5.1.1.2 Trees as a windbreak surrounding the property may influence the dispersion of viruses and bacteria from the barn and are recommended.

5.1.2 If at risk, the options to consider are:

5.1.2.1 Vaccinate for the diseases at risk if vaccines are available

5.1.2.2 Coordinate with neighbours by leasing or purchasing the nearby farm and providing pigs and protocols to the neighbour. Communicate the risk to your herd's health if a disease came through the hobby farm neighbour's animals. Develop a relationship so that you are notified about pig health problems.

5.1.2.3 Participate in regional eradication programs for specific high risk diseases such as PRRS virus.

5.1.3 When siting new barns, consider an isolated location of prime importance.

5.2 Transportation

5.2.1 Organize transport routes of breeding stock to avoid pig dense areas

5.2.2 Never park a breeding stock delivery truck at a stop with other pig trucks

5.3 Air filtration

5.3.1 A properly installed air filtration system has been very effective at keeping out aerosol spread diseases.
