Eurofins has modernized our pathogen detection methods to provide increased sensitivity and reliability, without changing the way your results are reported. This new Eurofins platform, BACGene, streamlines the process to give you faster turnaround time and is approved by the AOAC and AFNOR.
The table below outlines the 3 core buffers and their effectiveness of neutralizing common sanitizing agents in your facility. If you are purchasing your own environmental collection devices, we highly recommend utilizing Letheen broth whenever possible as it is most compatible with our laboratory methods. Devices with Letheen broth are cost-competitive and available from all major suppliers.
Please reach out to your testing laboratory with any questions. For more information on BACGene and other Eurofins testing kits, visit our Technologies page.
Compatibility of different broths
|Broth types||Quantitative Indicator Methods||Molecular pathogen detection|
Is the medium effective on sanitizing agents?
|Typical Sanitizing Agents||Letheen Broth||Neutralizing Buffer||D/E Broth|
|Quaternary Ammonium Compounds (Quats)||Yes||Yes||Yes|
|Peroxide or Peroxyacetic Acid||Yes||Yes||Yes|
Buffers are added to sponges and swabs to help neutralize sanitizer residue left behind in your facility by your cleaning and sanitation crew. While these buffers facilitate organism recovery for microbiology testing, certain buffer formulations can affect certain methods negatively. Work-arounds for incompatible methods exist but can significantly reduce the sensitivity of the method.
