17-Dec-2008 (17 years 5 months 21 days ago)“The 840 animal identification solution is an individual animal ID option with an added punch,” says Cindy Smith, Animal Plant Health Inspection Service administrator. “Not only can it improve the ability of U.S. animal-health officials to quickly respond to a disease outbreak, but the 840 AIN also helps producers simplify recordkeeping and reduce the number of animal identification systems they use. The 840 AIN is truly one number with many uses.”
