Premises Identification (PID) is one of the three pillars of traceability and links livestock and poultry to land locations or premises. PID was established to plan for, control, and prevent, the spread of animal diseases. It can also be used as an early warning system to notify producers of a natural disaster such as a flood or fire which could affect animals under their care.If you own, rent or for any other reason have control of a premises where livestock or poultry are grown, kept, assembled, slaughtered or disposed, you should obtain a PID number for that location. Participation in Saskatchewan’s PID Program is voluntary; however, it will only work if you join.PID links livestock and poultry to identifiable geographic locations for planning and managing during emergencies. The national traceability system is expected to encompass all livestock and poultry species produced in Canada. It is recommended that producers with other livestock species also apply for a PID number and be entered into the Saskatchewan PID Program.A PID number is a unique alpha-numeric identifier assigned to a parcel of land where livestock or poultry is grown, kept, assembled, slaughtered or disposed.The other two pillars of traceability are animal identification and movement reporting. Together with PID, these three pillars enable veterinarians and others to track where animals have been located and to identify other animals with which they have been in contact.
