BSE case confirmed in British Columbia
Ottawa -- The Canadian Food Inspection Agency (CFIA) has confirmed the diagnosis of bovine spongiform encephalopathy (BSE) in a mature dairy cow from British Columbia. The animal's carcass is under CFIA control, and no part of it entered the human food or animal feed systems.
Preliminary information indicates that the age of the animal (66 months) falls well within the age range of previous cases detected in Canada and is consistent with the recognized average incubation period of the disease. Medical News Today Link
No danger from young cows infected with BSE, Japanese experts say
Japanese experts have concluded that their tests failed to demonstrate that young cows infected with bovine spongiform encephalopathy posed any danger to humans, according to what Kyodo News called "informed sources."
Representing Japan's Health, Labor and Welfare Ministry, the team injected 11 mice with brain fluid extracted from two young BSE-infected cows in Japan and discovered that the rodents had not developed the disease up to 927 days after the injection, the sources said.
The 21- and 23-month-old cows were found to have been infected with BSE in 2003, prompting Tokyo to limit imports of U.S. beef to meat from cattle younger than 21 months old. FSnet Link
