Microbial Challenge Studies Overview

February 24, 2022, 1pm EST

Challenge studies are a valuable way to determine whether a specific food requires time-temperature controls for safety or is suitably formulated.  Various challenge studies such as shelf life, process, product, growth, and inactivation studies can be used to do this.  This webinar will discuss the reasons and needs for the different types of studies, and when best to perform each kind.



Target Audience:

  • Food Product developers
  • Factory or Laboratory Quality Technicians and Specialists


Learning Objectives:

  • Knowing why and when a Challenge Study is necessary
  • Differences between a Shelf life study and a Challenge study
  • Different types of challenge studies and what type is best for different situations
  • How we perform Challenge studies at NQAC


Course Length: 1 hour 

Instructors: Edith Zambrana-Santos, Sr. Microbiologist and Ryan Hartpence, Sr. Microbiologist, NQAC Dublin

Environmental Monitoring: Next Steps

ON DEMAND: Recorded previously

The strategic application of an environmental monitoring program (EMP) gives valuable insight into the hygienic state of a facility. It verifies that good manufacturing processes and pre-requisite programs work as intended.  When done well, an EMP recognizes when line health or the manufacturing environment begins to stray.  Often, associates are unsure of how to use root cause analysis (RCA), apply investigational sampling techniques, and drive sustainable actions for mitigating the source of contamination.

This webinar discusses an efficient approach, using real scenarios, for leading investigations when out-of-specification (OOS) quantitative and qualitative microbiological results occur in your facility.


Target Audience:

  • Factory or Laboratory Quality Technicians and Specialists


Learning Objectives:

  • Using a corrective action process for OOS EMP results
  • Creating an investigational plan
  • Tools for managing an RCA
  • Driving sustainable actions and collaboration


Course Length: 1 hour 

Instructor: Andrea Chmelar, Microbiology Operations Supervisor, NQAC Dublin

Andrea Chmelar is a Microbiology Supervisor and Environmental Monitoring Specialist at Nestle Quality Assurance Center and works directly with external factories to evaluate, improve, and design customized and effective Environmental Monitoring (EM) Programs.  Before that, Andrea worked exclusively as a Microbiology Operations Supervisor, where she specialized in leadership development and Lean process improvements.  Andrea’s strength lies in empowering and enabling associates through training and development of EM to build a more positive and proactive food safety culture. When Andrea is not in the lab or a factory, which isn’t often because pathogens don’t take vacations, she enjoys traveling to scenic destinations.  In addition to her food science education, she is also a certified culinarian.

Veterinary Drug Testing in Food: Analytical Approaches, Challenges, and Pitfalls

ON DEMAND: Recorded previously

Laboratory testing can offer critical information and peace of mind regarding the safety and compliance of your food, but the limits of testing can be overlooked or misinterpreted. Understanding how the test works and what the reported results tell you (and what they don’t) is an important step in identifying any blind spots that could lead to a false sense of security. Choosing the appropriate test, asking the right questions, and interpreting the report will help ensure the testing meets the needs of your business.

This webinar discusses the advantages and disadvantages of different analytical approaches for veterinary drugs in food and what the laboratory can and cannot assure you from the test result.


Target Audience:

  • Laboratory Staff and Quality Managers


Learning Objectives:

  • Technologies used in veterinary drug testing and what they bring to the table
  • Quantitative versus qualitative results
  • The importance of test validation for the food being tested
  • What questions to ask the laboratory to ensure the results will meet your needs

Foreign Body Materials: Management Principles and Root Cause Investigations

ON DEMAND: Recorded previously

While zero defects is the ultimate goal, nearly every food business will experience a foreign body incident at some point. Most businesses focus on microbiological hazards as they are the most well-known food safety risk, but foreign bodies also pose a risk and should not be ignored. While food manufacturers put controls in place to prevent foreign bodies from entering products, but even with safeguards in place consumers still find them on a frequent basis. A foreign body incident can have a huge impact on consumers and can even lead to product recalls.

This webinar discusses foreign body principles and introduces two fast and effective tools, FTIR and XRF, which are used to assist in the root-cause investigation and identification.

Key learning objectives:

  • Food safety impact of foreign bodies
  • Foreign body principles: build awareness, promote best practices and develop prevention plans
  • Analytical tools with a focus on XRF and FTIR to assist in root cause investigations
  • Real factory-level case study examples
