Check how completely a finished batch can be traced back to its raw-material lots: enter the units produced, the units traced to a source lot, and the number of lots used — the coverage a recall would rely on.
Try sample values — fills the form with the worked example below.
–
Traceability (%)
–
Average units per lot
–
Untraced units
Equation: Traceability (%) = units traced ÷ units produced × 100. Average units per lot = units produced ÷ lots used. Untraced units = units produced − units traced.
Method: Batch genealogy (traceability) per Codex CAC/GL 60-2006 (Principles for Traceability / Product Tracing) and the Safe Food for Canadians Regulations: every finished unit should link back through the production record to the raw-material lots it came from, so a recall can be scoped to the lots affected.
Assumptions: the traced figure counts units with a complete link to a source lot; the lots figure counts the raw-material lots actually used in the batch.
Limitations: traceability is a record check, not a guarantee — a 100% figure here means the records link, not that the records are correct; ingredient lots split across batches widen every recall that touches them.
Rounding: traceability to 2 decimal places; average units per lot to 2 decimal places; untraced units as a whole number; intermediates unrounded.
This is a calculation aid, not a laboratory report — confirm against your accredited method before citing a value.

Worked example: Batch of 10,000 units, 9,800 traced, 4 lots used: traceability = 98.00%; average = 2,500.00 units per lot; untraced = 200 units.
Enter values above to see results.
Anything under 100% is a gap to close before the next audit — find out why those units have no lot link. Tool 356 of 500 — GIFSQ
