The USDA Animal and Plant Health Inspection Service has lifted the quarantines on two Central California dairies associated with that BSE-positive cow found April 24th at a rendering plant.
APHIS says tests performed by World Organization for Animal Health labs in Canada and England confirmed the cow had atypical BSE, a rare, spontaneous form of the disease. USDA has reiterated: This animal was never presented for slaughter for human consumption, so at no time presented a risk to the food supply, or to human health in the United States.”
“In addition, investigation of the feed records at the index dairy premises has found no anomalies, and audits of all the feed suppliers to the index premises have shown them to be in compliance with the regulations.”
On May 2nd, APHIS announced they had traced two calves of the infected cow, one had been stillborn, the other was slaughtered and tested for BSE, and it was negative. The agency “Of several hundred potential birth cohort cattle, the focus of the tracing is on a small number (10-12) of cattle which may still be alive and have records that might allow them to be located. The remaining potential cohorts are no longer alive or have otherwise been ruled out.”
