ABSTRACT:
Retail establishment customers are prevented from unwittingly purchasing perishable items that may have been adversely affected by being subjected to at least one predetermined factor in that an identification object, such as a label, tag or packaging material, is provided with an initially machine-scannable bar code of such a character that its scannability is at least gravely impaired when the identification object is subjected to the predetermined factor. The identification object is secured to the respective item for both of them to be subsequently exposed to the same conditions such that a failed scan of the bar code occurring at the time of purchase alerts the customer to a previous occurrence among such conditions of the predetermined factor that may have adversely affected the item being purchased. In another aspect, a non-readable bar code is rendered readable by exposure to the predetermined factor, thereby alerting the customer.
