FIG. 8 shows a view of a common source and associated units in accordance with one aspect of the present invention.200, and additional transponder devices 211 a-b associated with units 210 a-b as they are split from the common source as shown in FIG. 8. The codes of the transponder assemblies corresponding to units split from the common source will preferably be associated with the code of the first transponder unit in a database 220. When the units are redistributed, the transponders may or may not be removed from the units. If the transponders are removed from the units, preferably the transponder codes are electrically associated with an identification of the individual units prior to distribution. In any event, each of the units split from the common source will preferably have a transponder code associated therewith and a user will preferably be able to utilize the database to track all of the units split from the common source once the user identifies either a package into which any of the units from the common source was provided for distribution, or a transponder code associated with any of the units split from the common source.

As is apparent from the discussion above, for purposes of the present invention a common source can be a plurality of separated units in a single container or an animal carcass, and in either event considered as comprising a plurality of units physically joined together (the meat carcass can be considered a union of individual meat units).

In compliance with the statute, the invention has been described in language more or less specific as to structural and methodical features. It is to be understood, however, that the invention is not limited to the specific features shown and described, since the means herein disclosed comprise preferred forms of putting the invention into effect. The invention is, therefore, claimed in any of its forms or modifications within the proper scope of the appended claims appropriately interpreted in accordance with the doctrine of equivalents.
