Former Secretary of Agriculture Ann Veneman asked the department to create a national livestock tracking system in 2003, when the first U.S. case of mad cow disease was discovered, The Wall Street Journal reported. There is still no such system for most farm animals, including chickens and beef cattle.
The Agriculture Department, which has spent $84.7 million to develop a tracking system, told the Journal such a system will begin operating next year, but has decided not to make the tracking mandatory.
Officials told the Journal they dropped the idea of mandatory participation because of industry feedback, and, instead, plan to rely on market forces to convince livestock producers to register their animals. Only if that doesn't result in adequate participation does the agency say it would again consider making the system mandatory.
Livestock tracking might be crucial in controlling outbreaks of contagious diseases by allowing investigators to quickly locate animals that were exposed to an infection, such as mad cow disease.
