Dr. Marshall is Chief Scientific Officer with Eurofins Microbiology Laboratories, Inc., a division of the global life sciences company Eurofins Scientific.  He is co-founder and Director of the Food Safety Institute, LLC, an integrated consulting and analytical services company affiliated with the Eurofins network of companies.  He is Technical Director for the Refrigerated Foods Association and Microbiology Task Force Chair for the American Spice Trade Association.  His former positions include the following:

  • Associate Dean and Professor of Public Health, College of Natural and Health Sciences, University of Northern Colorado
  • Adjunct Professor with the Colorado School of Public Health and Colorado State University
  • Professor of Food Science, Nutrition, and Health Promotion at Mississippi State University
  • Assistant Professor of Food Science at Louisiana State University
  • Contributing Editor for the peer-reviewed scientific journal Food Microbiology
  • Four consecutive terms on the editorial board of the Journal of Food Protection

He is a frequent volunteer and consultant to trade associations, NIH, WHO, FAO, USDA, and other government agencies and private companies.  His research and expertise has been featured in popular press venues such as Consumer’s Reports, Fine Cooking, USA Today, Fitness, Health, Men’s Health, Chemtech, Nature Science Updates, and ASM Journal Highlights.  He is a frequently invited speaker and a prolific book chapter writer. With over 250 publications, over 300 invited presentations, and over 100 workshops delivered, his scientific research and outreach interests focus on improving the microbiological quality and safety of foods, with emphasis on meat, poultry, seafoods, and produce.  Among these was the completion of the 4 volume Handbook of Food Science, Technology, and Engineering, which he Co-Edited.  He has been the recipient of a number of awards for his scholarly efforts including the Mississippi Chemical Corporation Award of Excellence for Outstanding Work, the International Association for Food Protection Educator and Harold Barnum Industry Awards.  He is a Fellow and former member of the Board of Directors of the Institute of Food Technologists, inaugural Chair of the International Food Science Certification Commission, and former member of the Board of Directors of the American Spice Trade Association. 

On a personal note, early in his career he served as a deck hand on an Alaskan fishing vessel (well before Deadliest Catch) and prefers to spend his free time lost on a trail in the Colorado Rocky Mountains.

In this episode of The Scoop, host Keren Breiterman speaks with Dave Ellingson, Director of Scientific Strategy for Eurofins Chemistry Testing Laboratories - Madison, about the role of phospholipids in infant formula and their importance in replicating the composition of human milk.


Phospholipids may be small molecules, but their impact is immense. By keeping them active and abundant in infant formula, we're taking one step closer to replicating the remarkable composition of human milk—and nurturing healthy development in every bottle. Click the link to learn how.


The use of real HMOs in infant formula is accelerating, driven by science, innovation, and a commitment to nourishing infants in the healthiest way possible. Enhanced testing methods are unlocking new capabilities—bringing us closer than ever to replicating the complexity and power of human milk. Click the link to learn more about HMOs.


In this episode of The Scoop, host Keren Breiterman speaks with Dave Ellingson, Director of Scientific Strategy for Eurofins Chemistry Testing Laboratories - Madison, about Human Milk Oligosaccharides (HMOs)—what they are, why they matter, and how they’re shaping the future of infant nutrition.


Low water activity foods (LWAFs) have historically been considered low-risk for microbiological hazards because their limited “free” (unbound) water in the formulation prevents bacterial growth. However, foodborne illness outbreaks revealed that pathogens can survive for extended periods in LWAFs, even in the absence of growth. Watch now to learn what is required to validate control measures to reduce microbial risks in LWAFs. Originally Aired on June 18, 2025.


From ancient remedies to modern lab techniques, the science of vitamins has come a long way. Vitamin analysis plays a key role in making sure we get the right nutrients, whether through supplements, food, or baby formula. Keep reading to find out how testing is becoming more precise and efficient.


California passed Assembly Bill 899, a law aimed at holding baby food manufacturers to a higher standard and mandating monthly testing of finished baby food products. As concerns grow about heavy metals in food, especially in infant formula, we must find a way to protect these vulnerable individuals. Read more about California Bill 899 by clicking the link.


Infant formula is often the sole source of nutrition for many infants, so it must be perfect. Testing standards can ensure that the nutrients in infant formula products are exactly at the level they are supposed to be and have become the guideline for measuring the quality of infant formulas. Learn what defines today’s testing standards—check it out now.


Modern infant formula is a remarkable achievement in nutritional science, meticulously designed to meet or exceed all essential dietary needs for infants. Read this editorial by Eurofins Food Chemistry Testing CSO, Darryl Sullivan to learn about the rigorous analytical testing and regulatory requirements that companies must meet to bring infant formula to market.


June 24th, 2025– In response to evolving regulatory expectations and growing public health concerns for Bisphenol A (BPA), Eurofins Food Chemistry Testing Madison, Inc. (EFCT) has expanded its advanced testing capabilities to detect and quantify BPA. Read our press release to learn more.
