From the Field Video Series

NEW! We are proud to introduce a series of educational video presentations from industry subject matter experts (SMEs) on topics we hope you will find insightful and interesting. Stay tuned for additional videos to be added to the lineup!

From the Field Series #2: Microbiological Criterion, this great stranger

Subject Matter Expert: François Bourdichon, Ph.D, Food Safety Microbiologist, Chair of the Standing Committee on Microbiological Hygiene, International Dairy Federation

Microbiological monitoring is often regarded as a regulatory mandatory and an adequate fail/pass approach to ensure safe food production. However, this is not what is expected from the evolution of the concept and the guidelines from the Codex Alimentarius on establishing microbiological criteria (CAC GL 21/1997 Modified 2015).

Apart from statistical considerations, there are a lot of technical details to be considered, not to mention the role of the criterion within the global food safety management system (FSMS) in place. The following presentation from the bioMerieux EDQC Event in Fall 2022 addresses the following considerations:

  • Always start with the WHY: Why do we test? (Risk Assessment)
  • What / How do we test? (Microbiological organism of concern, analytical method)
  • Where do we test? (Sampling point along the production process)
  • And how should we react to a result?

It is important to switch from a reactive to a proactive monitoring scheme, establishing sampling points where contamination and/or deviation can occur. Not at the end of the process where the only solution remaining is discarding eventually the noncompliant production.

The International Dairy Federation has published a dedicated bulletin on the practical considerations for sampling (IDF Bulletin #525). The bulletin is available at:

From the Field Series #1: Practical Tools for Membrane Process Monitoring and Filter Verification

Subject Matter Expert: Chris Pundmann, Process Engineer and Project Manager at Statco-DSI Process Systems

In this first From the Field presentation, Chris provides an understanding of the issues facing membrane hygiene and what can be done to develop an ongoing plan to monitor the performance and cleaning of your filtration systems.
