History
Peg Coleman began serving as a medical microbiologist and microbial risk assessor in the US federal government in 1992, and continued that work as founder in 2010 of the woman-owned small business Coleman Scientific Consulting (CSC). Peg’s assessments all address the extensive gaps in scientific knowledge of microbial risks and benefits in health and disease. She is recognized as a trusted adviser, invited expert, educator, and peer-reviewer for methodology to assess microbial risks, including attendant uncertainties due to limited data that is often ambiguous, fragmented, and indirect. Her unique knowledge and collaborative style supports development of coherent models that reflect not just statistical correlations, but more importantly the complexities of biological systems and underlying causal mechanisms.
Many assessments incorporate her insights from environmental and food chain exposures to pathogens from scenarios for intentional biothreat attacks and natural farm-to-fork systems. CSC work continues to raise challenges to use of outdated conservative assumptions that overestimate risk, underestimate uncertainty, and poorly reflect pathogen interactions in complex biological systems like the gastrointestinal tract. Recent manuscripts in the prestigious journals Human and Ecological Risk Assessment and Risk Analysis challenge the outdated assumptions of simple, convenient, but unfortunately, biologically implausible non-threshold models with low-dose linearity as the default for microbial dose-response assessment. These simple models exaggerate risk and underestimate uncertainty, misleading both policy makers and consumers.
CSC work on issues related to the microbiota of milks began in 2014 with a presentation entitled Exploring Disagreements Regarding Health Risks of Raw and Pasteurized Human and Bovine Milk at the Society for Risk Analysis (SRA) annual meeting. Since then, Peg has invested time and energy into leadership of a multi-year international project on the Microbiota of Milks, prepared seven manuscripts (five published to date), and presented on the microbiota of milks at events with SRA Past-President Warner North, Cornell University Emeritus Professor Rod Dietert, independent mathematical statistician Nick Azzolina, and database expert Michele Stephenson.
Peg and Warner presented a 2017 SRA webinar entitled Preparing to Deliberate Evidence on Benefits and Risks Posed by the Microbiota of Milks and a 2018 SRA symposium entitled Communicating Evidence for Benefits and Risks of Raw Milks.
Peg and Rod presented at a 2018 Upstate NY SRA event at the Cornell University College of Veterinary Medicine entitled Microbiome Benefits and Risks in Neonatology and Later Life.
Peg and Nick prepared a presentation for the 2019 SRA annual meeting entitled Data and Analysis Debunk Speculations about Raw Milk Risks.
Peg contributed to the 2019 poster entitled Producing Hygienic Raw Milk: Standards, Testing, and Farmer Education at the 16th International Symposium on Milk Genomics conference, Copenhagen, Denmark
Peg prepared and presented a 2021 SRA webinar entitled Resilience and the Human Superorganism: Give Us this Day our Daily Microbes
Peg presented on Recent Evidence for Benefit-Risk Analysis of Raw and Pasteurized Milks for 8th World Congress on Targeting Microbiota 2021 sponsored by the International Society of Microbiota
Peg and colleagues in SRA Applied Risk Management specialty group organized, presented, and facilitated dialogue in a workshop and two round table panel symposia on the Risk Analysis Quality Test (RAQT) and applications to risk assessments at the SRA annual meeting in Tampa, FL.

Peg presented recent lectures at three Universities:
o Microbiome and Immunology: Interactions for Risk Assessors from 21st Century Science at SUNY College of Environmental Science and Forestry at Syracuse (2018 to 2023, ENS 470, Environmental Risk Assessment)
o Considering Risk Management for Complex Systems at Ohio State University (2 lectures in PUBHEHS 7375 Quantitative Microbial Risk Analysis Modeling)
o Incorporating Food and Gut Microbiota into 21st Century Risk Analysis at University of Liverpool, Institute for Risk and Uncertainty, UK

Margaret (peg) Coleman
From her work developing Quantitative Microbial Risk Assessment (QMRA) methods for the US federal government to launching her own independent consulting firm in 2010, Peg has published in QMRA and food safety for more than two decades. In the past 7 years, she has published 9 microbial risk manuscripts in the prestigious journals Risk Analysis, Human and Ecological Heath Assessment, Applied Microbiology, and PLOS ONE. Peg is a natural leader and collaborator in multidisciplinary environments, providing a balance of expert knowledge, intellectual curiosity and people skills that clients trust. Connecting with the expanding literature on the microbial communities (microbiota) in foods and humans that relate to microbial risks and benefits is Peg’s sixth sense.
