Review spotlights why cattle field necropsies still lag
Bottom line
A new scoping review in Frontiers in Veterinary Science pulls together what’s known about field postmortem examination, or necropsy, practices in cattle production systems, and the picture is familiar but important: veterinarians and producers generally see field PME as valuable for diagnosing disease, determining cause of death, monitoring herd health, and supporting surveillance, but it still isn’t routine on many operations. The review, published October 15, 2026, identified 12 eligible studies from an initial 988 references and found recurring barriers including producer reluctance, time pressure, cost concerns, carcass disposal issues, biosecurity worries, and limited standardized training or continuing education for veterinarians. (frontiersin.org)
Why it matters: For bovine practitioners, the review reinforces that the challenge isn’t convincing the profession that necropsies matter, it’s building systems that make them workable in the field. Prior research has shown that postmortems can improve herd-level decision-making and outbreak detection, while newer work suggests real-time pathologist support by telemedicine may improve the odds of reaching a final diagnosis when whole-carcass submission isn’t practical. That makes training, protocols, sampling support, and client communication central issues, not side notes. (pmc.ncbi.nlm.nih.gov)
What to watch: Expect follow-on work to focus on standardized field PME protocols, continuing education, and telepathology models that could help rural cattle veterinarians improve diagnostic yield. (frontiersin.org)

Field necropsies are widely recognized as one of the most practical diagnostic tools available in cattle practice, but a new scoping review suggests the industry still hasn’t solved the operational barriers that keep them from being used consistently. In a Frontiers in Veterinary Science review published October 15, 2026, researchers from Texas Tech University School of Veterinary Medicine and collaborators found that field postmortem examination is valued across cattle systems for disease diagnosis, cause-of-death investigation, herd health monitoring, and surveillance, yet remains underused in routine field settings. (frontiersin.org)
The review set out to synthesize evidence on knowledge, attitudes, training, and barriers tied to field PME in cattle production systems. Using searches across PubMed, Scopus, Embase, Web of Science, and Google Scholar, the authors identified 988 references, removed 328 duplicates, screened 660 records, and ultimately included 12 studies. Their conclusion was straightforward: the evidence base is limited, and the literature points to a lack of standardized procedures and training practices that would support more consistent, evidence-based use of field necropsy in herd health programs. (frontiersin.org)
The barriers highlighted in the review are the same ones many bovine veterinarians deal with in practice. The paper cites producer reluctance, time constraints, economic considerations, carcass disposal challenges, biosecurity concerns, and insufficient PME training and continuing education as recurring obstacles. That matters because the value proposition for necropsy is already well established. Earlier literature describes field postmortem work as a way to maximize diagnostic investigations in production settings, while USDA foreign animal disease guidance underscores the importance of structured necropsy technique and biosecurity in cattle examinations. (frontiersin.org)
Additional research helps explain why this gap persists. A recent Canadian study on real-time pathologist-assisted field postmortems found that remote specialist support improved the success of reaching a final diagnosis compared with unassisted field examinations. That paper also notes that large-carcass transport, distance to diagnostic labs, turnaround concerns, prior inconclusive results, and cost can all discourage full laboratory submission. The same study cites an estimate that fewer than 1% of cattle that die before slaughter undergo postmortem examination, framing the issue as both a clinical and surveillance shortfall.

Industry-facing commentary has leaned in the same direction. BeefResearch.ca, summarizing the University of Calgary tele-necropsy work, said definitive diagnosis from necropsy can help improve herd health, biosecurity, animal welfare, food safety, and public health, especially when rural veterinarians can’t easily access pathologists or diagnostic labs. Inference: that makes the Vargas review less a critique of veterinary intent than a reminder that infrastructure, workflow, and access still shape whether good diagnostics happen on-farm. (beefresearch.ca)
Why it matters: For veterinary professionals, this review highlights a practical opportunity. If field PME is already accepted as useful, then the next gains are likely to come from better implementation: clearer protocols, stronger sampling guidance, more continuing education, and better communication with producers about diagnostic value and return on investment. It also points to a broader surveillance issue. When cattle deaths go unexamined, practitioners lose case-level answers, and the industry loses population-level intelligence on endemic disease, emerging threats, and management failures. (frontiersin.org)
There’s also a workforce angle. The review’s emphasis on training gaps aligns with broader cattle-health reporting that rural bovine veterinarians are stretched thin and that specialist access is uneven. Tools like telepathology won’t eliminate every barrier, but they may help bridge expertise gaps when a full diagnostic lab necropsy isn’t feasible. For mixed and food-animal practices, that could make field necropsy a more consistent part of herd investigations rather than a last resort. (frontiersin.org)
What to watch: The next step is whether this review translates into standardized field PME training modules, clinic-ready protocols, and more pilot programs testing telepathology, remote consultation, or decision-support tools in commercial cattle practice. Given the paper’s publication date of October 15, 2026, it’s also worth watching for conference discussion and follow-up implementation studies over the next 12 to 24 months. (frontiersin.org)
