Sir; The revelations on BBC1's Whistleblower this week about UK retail staff flouting food sell-by dates shows how easily handwritten labelling can be misused. Handwriting sell-by dates has a huge margin for error. The lack of control means that even without deliberate changes, staff run the gauntlet with possible mistakes. Advances in mobile printing technology mean food can be relabelled and prices updated quickly and efficiently with a hand-held printer. This allows consistent pricing throughout the store, and the margin for error is greatly reduced.
