A dairy cow from a Hokkaido farm has tested positive for mad cow disease, making it Japan's 11th case of the brain-wasting disease if formally confirmed, farm ministry officials said Sunday.
An expert panel under the Agriculture, Forestry and Fisheries Ministry will review the test data at a meeting Tuesday and issue a formal conclusion.
The National Institute of Animal Health in Tsukuba, Ibaraki Prefecture, conducted a second test on tissue from the dead cow after a preliminary analysis by a Hokkaido institute came back positive Friday.
