Embodiments of a method and system are described for tracing, for example, an animal's location history. These embodiments collect information such as a universal identifier, which uniquely identifies an animal and premise identifiers, which indicate a location or locations occupied by an animal. This collected data is transmitted to a secure data trustee that protects and screens the data so that confidential information is not released publicly. For example, when a public health issue arises, such as mad cow disease, the data trustee generates a traceback report indicating which animals have commingled with the infected animal. Based on the traceback report, other sick or potentially sick animals can be treated, quarantined, or slaughtered. As another example, the disclosed embodiments of the method and system facilitate commercial transactions by providing trace information that validates, for example, the animal health and food quality.
