Embodiments of a method and system are described for tracking and managing animals and/or food products. These embodiments can include entering into a computer system identification data for animals and location data for locations occupied by the animals. This data can be collected, for example, by a data service provider and transmitted to a data trustee. The data trustee may filter the data into official data and non-official data. The official data may be sent to an official database. When a public health issue arises, such as an occurrence of mad cow disease, the government may use an identifier for a diseased animal or a location identifier to request a trace report from the data trustee. The data trustee may then use the official data to provide a report showing, for example, which animals have commingled with the diseased animal. Based on this report, other sick or potentially sick animals can be treated, quarantined, or slaughtered. As another example, the disclosed embodiments may be used to facilitate commercial transactions by providing data that validates, for example, an animal's health and food quality.
