Other concerns in Wisconsin and other states (who contract with WLIC) is that the system is not maintained by state government, but instead relies upon the Wisconsin Livestock Identification Consortium (WLIC) to maintain the database of Premises ID registrants. This is currently continuing with the RFID tagging database as well. The WLIC is a private interest group made up of Big Agribusiness, including Cargill, Genetics/Biotech Corporations, like ABS Global, and RFID tagging companies such as Digital Angel, and many of these members parallel NIAA membership. There are also in fact only 6 RFID tags that are approved by WLIC/NAIS at this time: 2 manufactured by Allflex, 2 by Digital Angel, one by Y-Tex and 1 by Global Animal Management. All four are WLIC members.
