  • What sample matrix can MicroTally® be used on?
    MicroTally® is intended for use on any solid food where the presence of microbial pathogens or toxins, on the external surface of the product, are of concern. MicroTally® material, as a part of the manual and continuous sampling devices, has been approved by the USDA for beef trim sampling for pathogens and indicator organisms. MicroTally® has also been scientifically proven effective in sampling bacteria on produce such as lettuce.
  • What can MicroTally® NOT be used on?
    MicroTally® is not intended for some fine powders or liquids that may fill capture sites, interfering with the sampling process. MicroTally® should not be used if the suspected contamination is inherently internal to the product, and therefore not accessible for sampling.
