On-farm necropsy trends should be reviewed at least monthly to effectively catch subclinical disease, although in intensive production systems (such as poultry or young pig units), weekly or real-time reviews are preferred.

On-farm necropsy trends should be reviewed frequently and systematically to catch subclinical disease early, with specific analyses occurring weekly, monthly, and quarterly/annually depending on the goal.
Review Frequencies
Weekly: Noteworthy signs from post-mortem examinations are shared and discussed at least weekly among specialists to allow for rapid initial assessment and follow-up on potential issues. This helps in quickly identifying unusual cases that might require immediate investigation.
Monthly: Data derived from all monitoring components, including necropsies, are often combined and assessed monthly in interdisciplinary sessions with a team of specialists (pathologists, microbiologists, etc.). This allows for a more comprehensive look at current farm health status and emerging signals. Some early detection systems also apply algorithms to public health surveillance data on a monthly basis.
Quarterly/Annually: Data are formally analyzed on a quarterly and annual basis to monitor long-term trends, assess changes in the levels of unexplained disease compared to previous years, and evaluate the overall effectiveness of surveillance systems. Annual reports are often published and shared with stakeholders.

On-farm necropsy trends should be reviewed regularly, ideally monthly, to catch subclinical diseases early. Consistent monitoring allows for timely identification of patterns that may indicate underlying health issues in the flock.
