Listeria Environmental Swab PT Program (LS01): This program allows participating laboratories to report the presence or absence of Listeria and report the species identification if applicable to the laboratory. Along with laboratories that use this for accreditation, training, and/or internal use, it is a popular program for GFSI (SQF, FSSC 22000, BRC…) certified laboratories.
Salmonella in Liquid Egg PT Program (E01): This program allows participating laboratories to report the presence or absence of Salmonella and report the O and H antigens, and species identification, if applicable to the laboratory.
Cannabis/Hemp PT Programs (CASP): Proficiency testing programs for pesticides and cannabinoids are being developed and pilots for the program are scheduled for early 2022. Other areas to follow include heavy metals, residual solvents, terpenes, moisture, microbials, and mycotoxins.
