Event Surveillance
Livestock health-event surveillance connects weak and strong signals over time: animal or group identity, sensor and production changes, staff observations, housing or pasture context, movements, qualified examination and testing, response and outcome. Its job is to organize attention and preserve evidence—not to let an algorithm declare disease.

Visual explanationA diagram or operating scene makes the relationship visible.
Structured modelA flow, comparison, capability set, or boundary map organizes the idea.
Guided explanationOriginal prose connects the concept to its operating context.
01 / Overview
Watch for change,
then verify reality.
USDA research programs investigate on-animal and other sensor technologies as inputs to precision livestock management. APHIS traceability explains why animal, place and time connections matter during animal-disease investigations. Together they support a systems architecture, not a validated universal disease detector.
Useful surveillance keeps measurements, model outputs, alerts, staff observations, production events, environmental evidence, movements, veterinary findings, laboratory results and official classifications as separate evidence types with named authority and timestamps.
02 / Evidence flow
Detect, qualify, observe,
escalate, learn.
01DETECT / 01Receive a bounded signalAnimal or group, device or source, variable, timestamp, baseline, model or rule version, priority, latency, gaps and original alert
02QUALIFY / 02Check identity and system stateAssignment, attachment, power, coverage, sensor quality, production event, housing or pasture, weather, feed, water, handling, movement and recent change
03OBSERVE / 03Use trained physical reviewAnimal, group and environment observations recorded separately; immediate welfare action; veterinary or official escalation through the current plan
04CLOSE / 04Preserve outcome and feedbackQualified findings and tests, decision authority, action, movement controls where directed, outcome, unresolved status, false or missed event and model or workflow review

04 / Practice
Keep the event timeline
auditable and correctable.
Retain context and change
Keep individual and group baselines, sensor and software versions, feed, water, weather, housing, handling, reproduction, movement and other management events visible.
Separate alert from case
Record who opened, reviewed, escalated and closed an event; preserve observations, tests, authority, actions, uncertainty and outcome without rewriting earlier evidence.
Review false and missed events
Examine data gaps, delayed messages, identity faults, threshold changes, alert burden, response time, unresolved cases and change-driven validation with veterinarians and vendors.
05 / Boundaries
Early warning is not
early diagnosis.
No diagnosis, case definition, test interpretation, treatment, isolation action, movement restriction or reportability conclusion is provided.Use the current veterinarian-led herd plan and applicable animal-health and public-health authorities.
Never delay urgent animal care while waiting for a sensor, model or dashboard.Physical observation, trained people, safe handling and established emergency escalation remain primary.
Performance does not transfer automatically.Species, age, production stage, device, attachment, behavior, housing, pasture, climate, management, software version, outcome definition and validation population matter.

Qualified, time-series activity or position estimates can support attention inside health-event surveillance when device quality, model version, management context and physical verification remain visible.
observe / Precision livestockLivestock Housing Environmental Monitoring ↗adds occupied-environment context to
Housing zone, weather, ventilation, water, bedding, equipment and animal observations can add context to a health event without establishing its cause.
connect / Precision livestockElectronic Livestock Identification and Traceability ↗adds animal, premises and movement identity to
Authorized animal, group, premises and movement records can help bound surveillance and investigation while farm alerts and official traceability remain distinct systems.
connect / Farm operationsFarm Biosecurity Movement Records ↗can trigger authorized movement review in
A qualified health concern can prompt review of related animal, person, vehicle, equipment and material movements only through the current veterinary and official response plan.
act / Precision livestockPrecision Livestock Feeding Systems ↗adds ration, delivery, refusal and behavior context to
Feeding evidence can support surveillance but never turns a change in intake into a diagnosis.
decide / Livestock feed assuranceAnimal Feed Nonconformance and Recall Coordination ↗adds bounded animal observations and qualified findings to
Animal evidence can initiate or refine review but must remain separate from feed-cause conclusions.
