Considerations when selecting microorganism tests.

  • Microbial Indicator Comparison for Dairy

    Selecting the appropriate method for Aerobic Plate Count (APC) testing can be challenging as there are various testing methods from rapid automated methods to traditional cultural methods. It’s important for a laboratory to understand which method best fits their needs. Read how three global Standard Methods Agar manufacturer’s products were compared to 3M Petrifilm Aerobic Count Plate to determine if there are differences in each media’s performance when evaluating consistency.

3M™ Petrifilm™ Plates: Certifications & Validations.

Third-party validations such as AOAC confirm that the method has been scrutinized to prove that it is reliable, repeatable and has performed equal to or better than the reference method to which it was compared.

  • AOAC® Performance Tested Methods℠ (PTM)

    Confirms that the method has been tested in an independent laboratory. The method is reviewed yearly to ensure that there have been no changes to the method or quality assurance testing.

  • Ensures that the method will perform as stated in the instructions for use and that the method has been thoroughly tested in a collaborative study. Such collaboratively studied methods can then be included in Federal Code of Regulations, and federal agencies such as the FDA and USDA can add them to their code of approved methods, adding to the customer’s confidence in the product.

  • Methods carrying the NF mark have been thoroughly tested in a rigorous protocol that includes a method comparison and a collaborative study carried out by a certified expert laboratory. Also includes regular audits of manufacturing sites. NF certificate is valid for four years, then reevaluated and renewed, giving the customer confidence that the product’s performance remains consistent year after year.

  • MicroVal is an international certification organization for the validation and approval of alternative methods for the microbiological analysis of food and beverages. A MicroVal Certificate shows that a proprietary method performs equally well as the traditional, internationally standardized method. MicroVal certificates are valid for four years upon which they can be renewed.
