Japan reports 24th mad cow case
A 14-year-old female cow raised for beef in Japan's southern Nagasaki prefecture has been confirmed to have contracted the mad cow disease, a panel of the Japanese Ministry of Health, Labor and Welfare said Friday.
This is the first mad cow case in Japan with a cow raised for food. Former 23 cases of bovine spongiform encephalopathy (BSE) have all be found with diary cows aged 1 to 9 ages, Kyodo News quoted ministry officials as saying.
The cow, of domestic Japanese breed, was raised in a farmhouse in Nagasaki and had given birth to ten cows before it was sent to a meat processing plant.
The cow was suspected to have infected the disease on Monday. Its sample was later sent for re-examination and the result was positive.
On Wednesday, Japan reported its 23rd mad cow case, as a 68- month-old diary cow on a farm in northern Hokkaido was confirmed to have contracted the brain-wasting disease.
Japan discovered its first mad cow case in September 2001. The government later started introducing measures to screen every cow slaughtered for consumption.

O.K. we now have atypical BSE/TSE in Japan, of which we know does NOT look like nvCJD, but looks exactly like sporadic CJD, WE now know that BSE/TSE infectivity is showing up in atypical BSE cases in Japan, WE now know that the first case of nvCJD in Japan seems to be atypical as well, more like sporadic CJD.

A detailed description of the first case of variant Creutzfeldt-Jakob disease (vCJD) in Japan, originally reported in February 2005, has just been published [1,2]. The patient was a 51 year old man, who had spent around 24 days in the United Kingdom in 1990, during the bovine spongiform encephalopathy (BSE) outbreak. He is known to have eaten mechanically recovered meat during his visit, and although exposure in other European countries he visited, including France and Japan, cannot be excluded, it is thought that he may have been exposed to the BSE agent during his UK visit. If exposure in the UK was the source of his infection, then the incubation period to illness onset was 11.5 years.
It is also noted that the patient's illness duration was unusually long, at 42 months, and that periodic synchronous discharges (PSD), which have not been reported in other vCJD cases, appeared on the patient's electroencephalogram, 12 months before death. The working group reporting on the case suggest that the World Health Organization vCJD case definition [3] be revised to state that PSD does not exclude the possibility of vCJD.
