Connect epidemiological evidence, food or animal sources, diagnostic isolates, sequencing results and response actions across organisations. The BioChain doesn’t determine causality — it preserves the provenance of the evidence used to investigate it.
A single suspected outbreak can generate evidence across agriculture, food production, diagnostics, genomics, epidemiology and public-health response, often within days: a farm, flock or crop record; a processor or distributor record; a diagnostic sample and isolate; a sequencing run; a genomic analysis comparing it against reference data; an epidemiological case investigation; and, eventually, a recall or control action.
Each of those pieces is usually generated by a different organisation, using a different system, under a different legal basis for holding the data. During an active investigation, that fragmentation is manageable through direct coordination between the people involved. Afterwards — when the investigation is reviewed, challenged, or used to inform the next one — reconstructing exactly which evidence supported which conclusion, and when it became available, is often much harder.
The BioChain does not investigate outbreaks, and it does not determine causality. It preserves the provenance of the evidence used in the investigation: which isolate came from which sample, which sequence came from which isolate, which epidemiological finding was available at which point, and how those pieces connected to the eventual response. Each participating organisation continues to operate its own systems, under its own governance, sharing only the provenance relationships needed to reconstruct the investigation later.
Once an outbreak investigation closes, can anyone reconstruct exactly which evidence supported which conclusion, and when it became available?
That question matters for after-action review, for legal or regulatory scrutiny, and simply for institutional memory the next time a similar event happens somewhere else.
The five steps are the same everywhere. Here is what each one connects in this context.
No. Interpretation and causal reasoning remain with the epidemiologists, laboratories and public-health teams involved. The BioChain preserves the evidence trail connecting the data they work with.
Often, yes — because what is shared is the provenance relationship between records, not necessarily the underlying data itself. The right arrangement depends on the organisations and data involved, and is worth discussing directly.
That depends on the governance arrangement agreed between participating organisations before the investigation begins. The BioChain does not impose a default ownership model.
It works best when the connections are already in place before an outbreak occurs, which is why we recommend establishing this ahead of an active investigation rather than during one.
