2.4.2. Wholesale and Retail Horticultural Postharvest Losses

Wholesale and retail losses were determined by individually counting the number of unsaleable fruit based on a sub-sample of 3 × 10.80-kg cartons at the wholesale stage, and a subsequent 1 × 10.80-kg carton at the retail stage. Wholesale losses of the sub-sample were determined on point of arrival at market. Retail losses of the sub-sample were determined at the end of the retail period, when the last of the sub-samples was sold to consumers. For SC1, this was done using simulated conditions following a period of refrigerated storage with the retailer. The sub-sample was collected from the retailer to be held under ambient conditions for 24 h simulating the display period prior to consumer purchase in the retail store. For SC2, the wholesale and retail enterprises were combined, located within the same outlet. Wholesale losses were determined as in SC1. Retail losses were determined by the retailer using a logbook to document daily losses, consistent with the *FLW Accounting and Reporting Standard 2016* [40].
