RPM Tuesday Night Live: DCM and Raw Safety with NICCI CAMMACK

In this live panel, hosts Dr. Conor Brady, Dr. Brendan Clarke, and guest Dr. Nikki Cammack discuss a range of topics relevant to raw and minimally processed pet nutrition. Dr. Cammack explains metabolomics— the study of all small‑molecule metabolites in biofluids such as urine— and its potential to identify disease states and dietary effects in dogs. She then describes her large international survey of raw‑fed households (5,600+ respondents from 62 countries) which found zero laboratory‑confirmed pathogenic infections, highlighting the rarity of confirmed cases despite anecdotal concerns. The conversation moves to the dilated cardiomyopathy (DCM) controversy, where the panel agrees that current data do not support a causal link between grain‑free or raw diets and DCM, noting the low overall prevalence (0.5‑1.1% of ~80 million US dogs) and the confounding influence of genetics and diagnostic misclassification. Regulatory issues are examined: the US FDA’s zero‑tolerance policy for pathogens applies to all pet‑food formats, while the NOVA classification (minimally processed vs ultra‑processed) is advocated to improve labeling consistency. The panel critiques the pet‑food industry’s lack of transparent nutrient analyses and digestibility studies, explaining how without these data the safety and nutritional adequacy of both raw and kibble products remain uncertain. High‑pressure processing (HPP) is presented as a method some manufacturers use to reduce pathogens without compromising nutrients, though opinions differ on its impact on beneficial microbes. The discussion also touches on methodological advantages of metabolomics for non‑invasive biomarker discovery (e.g., early markers for Parkinson’s, Alzheimer’s, cancer) and how such tools could advance veterinary medicine. Looking forward, the speakers highlight upcoming longevity research, the need to re‑frame raw feeding within a sustainability context, and the carbon footprint of meat‑based diets. The episode ends with plans for future guests and a call for community support via Patreon. Key take‑aways: metabolomics offers a powerful, non‑invasive window into canine health; large‑scale raw‑food surveys show negligible confirmed pathogen risk; current evidence does not substantiate a DCM‑raw‑food link; pet‑food regulation and labeling need harmonisation; transparent nutrient and digestibility data are essential; HPP can improve safety without major nutrient loss; and broader research into nutrition, longevity, and sustainability is needed.
