J. David Legan, PhD
Director of Science
David earned his Ph.D. in Food Technology from the University of Reading in the UK by modeling the ecology of mixed microbial populations, and then moved to Campden BRI in a variety of microbiological food safety research and client service roles. During that time, he was project lead for the Bacillus component of the UK’s pathogen modeling program. He moved again to Nabisco Research in New Jersey where he ran the corporate microbiology lab and developed a program of preservation technology development and microbial modeling. After the Kraft Foods acquisition, he moved to Chicago to work on Food Safety and Preservation research, and through modeling and validation studies:
- Optimized Oscar Mayer’s use of lactate and diacetate and their naturally cultured alternatives as Listeria-control agents in Ready to Eat meats
- Specified process conditions central to Oscar Mayer’s commercial launch of High Pressure Pasteurization of naturally cured RTE meats
David had responsibility for the Kraft cultures R&D group, developed a partnership to explore microwave sterilization leading to several patents, and led a program that developed an internal proprietary natural antimicrobial commercialized in several Kraft products. Technologies from his group supported approximately $4 billion in annual sales.
After years as a microbiology "client", he is now back in the "provider" role as Director of Science at Eurofins Microbiology Laboratories, Inc., by way of the Covance Food Solutions group based in Madison, WI, which he joined in 2016. In this role, he ensures appropriate method validation, explores new testing technologies, and fields multiple complicated food microbiology questions.
Products that his team has evaluated or developed and launched include:
- The 3M MDS platform in the Madison microbiology laboratory
- Flow cytometry for enumeration of probiotics
- Strain-level confirmation of probiotic identification using the polymerase chain reaction (PCR)
- Next-generation sequencing using the Oxford Nanopore Technologies GridION sequencing platform for microbial identification and microbiome analysis

The reclassification of the genus Lactobacillus into 25 different genera has direct implications for the probiotic industry. This webinar describes the rationale behind the name change, what it means for the industry, how the taxonomy update will be implemented, and why it is a good thing for the consumer.
Do your products need a nutritional label? Do you ever find yourself facing confusion around nutritional labeling requirements?
Let us help with those questions! Listen to our informational webinar presented by Mollie Hammerschmidt, Analytical Services Manager, Eurofins Nutrition Analysis Center. She answers the most common questions and pain points we receive, from customers just like you, with nutrition labeling requests.
Are you stuck on the proverbial micro testing loop? Do you submit a sample to the lab, get a non-compliant result, fill out some paperwork, visit a field and then just start right back over at step one? If so watch this webinar on how to fix those issues.
You walk the field, you pick some product, and you drop it off at the lab for testing. Not long after, you hear back your sample is presumptive. Now what?
In this presentation, USP and Eurofins Microbiology provided an overview of USP microbiology methods tests for microbial contamination in dietary supplements, CBD/hemp products, and probiotics. The session included an in-depth discussion regarding the importance of suitability testing, and a comparison of USP methodology to AOAC/FDA BAM methodology. USP also provided an update on new USP chapters and shared insight on what is on the horizon for USP methods.
This presentation is focused on potential hemp regulations and their related dietary supplement regulations. Some topics during this discussion include section 321(ff)(3)(B) of the FD&C Act and its impact on hemp ingredients, new dietary ingredient requirements and preparation to meet federal regulations for dietary supplements, including dietary supplement Good Manufacturing Practices, should FDA or Congress recognize hemp extracts as lawful dietary ingredients.
This online presentation announces the establishment of a groundbreaking partnership. Backed by a grant from the US Department of Commerce, the United Natural Products Alliance (UNPA) and National Animal Supplement Council (NASC) have partnered with the China Society for Inspection and Testing (CSIT) and Eurofins to establish a qualification program focused on high-quality botanical and nutritional ingredients from China, and to provide new direct access to the Chinese consumer market for US dietary supplements for humans and pets.
Off-flavor and off-odor issues can damage your brand reputation and even result in recall. Watch our webinar to learn how Eurofins uses gas chromatography with mass spectral detection (GC-MS) to provide solutions for off-flavors, off-odors, and flavor scalping caused by improper product packaging, or production or transportation issues. This webinar was originally recorded on October 01, 2020.
Our webinar hosted by Dr. Neal Craft, Chief Scientific Officer of Eurofins, explores the world of natural pigments, testing methods, and unique matrix challenges.
