What is Agricultural supply system traceability, Part II: Implications of packhouse processing transformations about?

This paper describes four such concepts for horticultural packing operations: precision of traceability; packs per bin for tracking; bins per pack for tracing; and purity to describe the likely sampling accuracy of packs in an audit or monitoring system. Three major factors influence these measures: splitting the cupstream into a number of outputs during packing; any mixing that occurs before splitting; and any mixing that occurs after splitting. At low percentage cupstream, pack size, and packing lane mixing have marked influence over a broad range of traceability precision. Infeed mixing has a relatively minor effect. At high percentage cupstream, pack size, and packing lane mixing have minor effects and only a narrow range of traceability precision is dependent on these. Infeed mixing is the major determinate of traceability precision. Improvements in the precision of tracing gained from a change in granularity will always have an associated counter effect on the precision of tracking. Improvements to the precision of traceability achieved through reductions in mixing or output splitting improve the precision of both tracing and tracking. The traceability metrics investigated in
