2. National Swine Farm-Level Biosecurity Standard

2.1 Direct Route of Contamination

Direct route of contamination refers to the transmission of pathogens between infected and non-infected pigs through pig-to-pig contact, semen and embryos. The three major biosecurity risks addressed in this section are those related to the introduction of live animals, semen and embryos from domestic and foreign sources.

 

+ 2.1.1 Live Pigs from Domestic Source

Live Pigs from Domestic Source Limit the risk of introducing pathogens through incoming live pigs from a domestic source.
Rationale

Live pigs are an important potential source of pathogens.

Principles

Examples of Best Management Practices:

For more BMP refer to Section 4.1 of the User Guide.

Segregation

Introduce only animals of known and acceptable health status.

Limit frequency of new animal introduction

Isolate/quarantine new animals and observe daily

Sanitation

Clean the isolation facilities between batches.

Maximize downtime between animal batches.

Flow Management

Farm level: Use all-in/all-out placement of pigs within a barn or site to minimize risk.

Production system level: Report any unusual disease observations to the veterinarian responsible for the health status of the production system to allow for a timely intervention to prevent spread through contaminated animals.

Records

Record all introductions, placements and removals of animals so that, if an infectious disease is suspected, the animals or group of animals can be quickly traced and isolated.

+ 2.1.2 Semen and Embryos from Domestic Source

Semen and Embryos from Domestic Source Limit the risk of introducing endemic disease and emerging pathogens into the herd through semen and embryos from a Domestic source.
Rationale

Some pathogens, like PRRSv, can be transmitted through semen.

Principles

Examples of Best Management Practices:

For more BMP refer to Section 4.1 of the User Guide.

Segregation

Minimize the number of sources to the minimum needed for genetic progress and commercial needs.

Sanitation

Verify that pig transport companies have defined biosecurity protocols for delivery vehicles and drivers.

Flow Management

Farm Level: Use barriers and packaging protocols to avoid cross-contamination on delivery of semen.

Production system Level: Put in place a defined health status or biosecurity semen purchasing policy for the farm or the whole production system (as applicable).

Records

Keep a current boar stud health report on the farm.

+ 2.1.3 Live Pigs, Semen and Embryos from a Foreign Country

Live Pigs, Semen and Embryos from a Foreign Country Limit the risk of introducing endemic disease, emerging pathogens and foreign animal disease into the herd through live pig semen and embryos from a foreign country.
Rationale

In addition to CFIA legal requirements for import, it is important to investigate the endemic disease status of the supply herd and its status regarding potentially new emerging diseases that could be introduced to Canada.

Principles

Examples of Best Management Practices:

For more BMP refer to Section 4.1 of the User Guide.

Segregation

Limit breeding activities with foreign purchased semen to quarantined animals only.

Sanitation

Wash, disinfect and dry the quarantine facility between batches.

Flow Management

Production system Level: Ensure that the production system veterinarian approves the purchase of animals and/or embryos from outside Canada.

Records

Record the vet-to-vet conversation with the veterinarian in charge of the foreign source supplier.
