Our third processor forum in September attracted about 30 industry participants, which was a terrific result.

The focus of discussion was that testing for E.coli is critical in dairy processing for identifying process failure and, conversely, for verifying effective process controls.

The forum heard that E.coli is generally an indicator organism, i.e., there has been a process failure and it may signify a more serious pathogen (e.g., Salmonella) may be present. And, that some E. coli have mutated over time to be able to make and transmit Shiga toxin – Shiga Toxigenic E.coli (STEC), a much more serious public health concern.

Those in attendance appreciated the learnings conveyed from case studies in terms of key issues and root causes associated with E.coli detections.

The take home message was ‘identify where the contamination has come from and prevent the process failure from recurring’.

The origins of E.coli from previous case history include:

  • Build-up of trapped organic matter in equipment at joins, bends, faults (cracks).
  • Brine contamination (which can act as a transfer point).
  • Poor personal hygiene.
  • Poorly trained or supervised staff.
  • Cross contamination at packing.
  • GHP and GMP failures.
  • Tradies working in production areas without appropriate induction and PPE.
  • Insufficient hot water for cleaning.
  • Sub-par cleaning.

Save the date invitations for the next forum will be circulated soon and we’re very keen to receive your suggestions for the key theme for Forum Four.
