How are poultry dispositions entered into PHIS?

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

Answer: (C)

The concept here is that PHIS dispositions are tracked at the level of a defined group of birds, a lot. A lot is the unit that represents a specific, homogeneous group that moves through production together and shares the same health and processing history. Entering dispositions per lot aligns with how poultry operations are managed and how traceability is maintained, making it straightforward to monitor the fate of that entire group.

Recording by lot supports clear reporting and recall if needed. If dispositions were entered per shift, per producer, or per individual bird, data would become fragmented and harder to aggregate for a defined flock or for epidemiologic tracking. In practice, when a lot reaches a final disposition (sold, condemned, processed, etc.), that status is applied to the whole lot, not to individual birds or narrower subsets.
