42. A radio frequency identification tag configured to track a food handling or consumption, comprising:
-
an interrogation interface; and a food-attribute-identification circuit including a memory array having one or more data elements associated with a food attribute, the one or more data elements including a make or break conductive coupling that breaks contact responsive to exposure to one or more food handling, preparation, or consumption conditions. - View Dependent Claims (43, 44, 45)

46. A radio frequency identification tag, comprising:
-
a food-attribute-identification circuit; and a decomposable interrogation interface, the decomposable interrogation interface decomposable responsive to exposure to a food handling, preparation, or consumption condition. - View Dependent Claims (47, 48, 50, 51, 52, 53, 54, 55, 57, 58, 59, 60)

61. A system for determining a food condition, comprising:
-
a radio frequency interrogator configured to interrogate one or more radio frequency identification tags carried by food; and a controller operatively coupled to the radio frequency interrogator, and configured to decode data from the one or more radio frequency identification tags to determine one or more food conditions corresponding to the data.

63. A radio frequency identification tag configured to track a food handling or consumption, comprising:
-
a radio frequency interface; and a memory array operatively coupled to the radio frequency interface, the memory array including one or more data elements having a make or break conductive coupling that change state responsive to exposure to one or more food handling, preparation, or consumption conditions. - View Dependent Claims (64, 66, 67)

71. A radio frequency identification tag comprising:
-
an edible substrate; a radio frequency transceiver integrated circuit disposed on the edible substrate the integrated circuit including programmable storage adapted for storing a unique identification code; and at least one antenna for receiving and transmitting radio frequency signals disposed on the edible substrate the antenna electrically coupled to the radio frequency transceiver integrated circuit, and having portions configured for enabling the tag to be selectively modified to adjust the receiver sensitivity of the radio frequency identification tag, wherein the receiver sensitivity is initially to radio frequency signals transmitted at a first distance from the radio frequency identification tag and after an adjustment by modifying the portions configured to be modified, the receiver sensitivity is to radio frequency signals transmitted at a second distance from the radio frequency identification tag that is less than one half the first distance.
