How the PT trials are arranged

  • PT trials are arranged 4 times a year
  • Participants receive their samples in good time before the trial starts. The participants analyze their samples in the same 2-weeks period.
  • Participants submit their results within a final date, and receive a preliminary report approximately 2 weeks after the final date.
  • A final report is made available in approximately 5-6 weeks.
  • Due to holidays in the summer and around Christmas, the reports may be delayed.

The PT food program is divided in 3 different groups; non-pathogenic samples, pathogenic samples and samples for Thermotolerant Campylobacter and Pathogenic Vibrio spp.
