This Seed Program Specific Work Instruction (SWI) outlines the procedures for sampling seed for the purpose of obtaining a representative sample of a seed lot. Proper sampling technique is necessary for an accurate estimation of seed lot quality. To be practical and effective, testing and verification must be conducted on a timely, accurate and uniform basis. Sampling for export certification, marketplace surveillance, verification of automated samplers, and complaints and investigations must be conducted by certified samplers (official seed samplers). Quality System Procedure (QSP) 132.4 Official Seed Sampler Certification provides details on the certification process.

This SWI is intended to be used:

  1. by inspectors, who are training for official sampler certification or who are sampling for purposes that do not need to be performed by an official seed sampler;
  2. by CFIA samplers who are certified;
  3. in all cases when CFIA official samples are drawn;
  4. as a reference for all quality system documents with a seed sampling component.
