The invention provides a method and system having a computer system and imaging sensors that capture image data of an object, such as a carcass, as it moves through a processing facility and is converted into individual food products. The computer system analyzes the image data to produce a blob for the object being monitored. Source information that is referenced with the object being monitored can be associated with the object's blob. The blob can be used to track and identify the object, and to determine when one or more additional objects have been converted from the object being monitored. The computer system can create blobs for the additional objects and associate the referenced information with the new blobs. In one embodiment, the computer system is capable of continuously associating the source information for a particular source unit of food with converted food products that are converted from the source unit.
