According to the reports, officials from USDA said that the herd contains a single month-old bull calf that was born to the infected cow. The precautionary measure is expected to take place this week.
The announcement of the first reported US case of mad cow disease on 23 December shook the €21 billion US cattle industry and saw more than two dozen nations immediately halting US beef imports, which accounted for about $3.2 billion in annual sales.
The European Union imports little US beef because most is reared using hormones banned on the EU market.
Also known as BSE (bovine spongiform encephalopathy), mad cow disease is linked to the deadly variant Creutzfeldt-Jakob Disease (vCJD) in humans from which about 130 people have died, mostly in Britain.
According to the US media reports, the USDA chief veterinarian Dr. Ron DeHaven said at the latest USDA briefing on BSE that none of the killed animals remains will enter the human food chain.
Dr. DeHaven said that the USDA is still looking for the whereabouts of 70 other cattle that entered the US from Canada with the infected Holstein dairy cow more than two years ago.
How this recent mad cow case will impact the global meat trade - just recovering from a fall in 2001 to its lowest levels in 13 years - but supporting a rise of 3 per cent in 2002, is as yet unclear.
