How are poultry dispositions entered into PHIS?

• A. per shift
• B. per producer
• C. per lot
• D. individually

Answer: (C)

Dispositions are entered into PHIS per lot. In poultry operations, birds are tracked in batches or lots rather than individually, because a lot represents a defined group from a single origin that moves together through production and processing. Recording the disposition at the lot level is efficient and matches how data is collected and reported for traceability and recall purposes. For example, if a lot of 5,000 birds from one farm is scheduled for processing and a portion is condemned, you update the disposition for that entire lot and note how many birds were affected, rather than entering each bird separately.

Other methods would be impractical or misaligned with how PHIS tracks data: recording by shift focuses on time rather than batch, by producer would tie to the source rather than to the disposition event, and entering individually would create excessive data entry without adding value to traceability. So, per lot is the standard approach for poultry dispositions in PHIS.
