Ep. 36. Mike Cramer: Environmental Monitoring and Listeria Control

Michael Cramer is currently the senior director of food safety and quality assurance with Ajinomoto Windsor, Inc. The company was formed through various acquisitions (Multifoods, Specialty Brands, and Windsor Foods) and ultimately the purchase of Windsor Foods by Ajinomoto. He will celebrate his 25th year with the company in October 2018.

Mike is an SQF practitioner, ASQ-certified quality auditor, and a preventive controls-qualified individual. CRC Press published Mike's book “Food Plant Sanitation: Design, Maintenance and Good Manufacturing Practices” (2nd Edition, 2013).

Mike is a graduate of West Chester University in West Chester, PA where he earned a B.Sc. Health Science in 1977. He spent 16 years working with Swift & Company (Armour, Swift – Eckrich, ConAgra) in poultry operations, processed meats and poultry, and corporate food safety and quality assurance.

Finally, Mike has been an esteemed member of Food Safety Magazine's Editorial Advisory Board since 2001.

In this episode of Food Safety Matters, we speak to Mike Cramer about:

  • Why Listeria continues to be a challenge in food plants
  • Qualities that a food facility—and its staff—should have in order to tackle Listeria and environmental monitoring issues
  • The financial burden of setting up an environmental monitoring program, and why it's necessary
  • Implementing a program that is designed to look for Listeria spp., not just Listeria monocytogenes
  • What happens when regulatory inspectors come in to conduct swabbing
  • The pros and cons of testing in an in-house lab vs. a third-party lab
  • Testing methodologies: cultural method, polymerase chain reaction, VIDAS, lateral flow devices, etc.
  • What should happen when positive test results are confirmed
  • The Ishikawa process and how it relates to getting to the root cause of environmental problems
  • The importance of having a cross-functional team in place to attack Listeria harborage from all angles and departments
  • Implementing chemical and mechanical actions to rid a plant of biofilm
  • How the dirtiest areas of a food facility don't automatically equal Listeria contamination
  • Sanitary design and hygienic design
  • Quat, peroxyacetic acid, chlorine dioxide, silver dihydrous chloride, and other options for sanitizing
  • Taking advantage of industry conferences, events, and new technologies to hone in on what a particular food business needs to know to improve food safety operations
