New variant Creutzfeldt–Jakob disease (vCJD) was first identified in the UK in 1996, and was causally linked to bovine spongiform encephalopathy. Herein we report the first case of vCJD in Taiwan: a 34-year-old man who had lived in the UK between 1989 and 1997. The patient presented with depression, irritability, personality change, painful feet and allodynia, followed by gait ataxia and cognitive impairment. Electroencephalograms did not show the typical appearance of sporadic CJD. The cerebrospinal fluid 14-3-3 protein immunoassay was negative. Brain magnetic resonance imaging revealed high signal lesions involving bilateral caudate nuclei, left lentiform nucleus, bilateral dorsomedial thalami and pulvinar on fluid-attenuation inversion recovery, T2- and diffusion-weighted imaging. Prion protein gene analysis showed homozygous for methionine at codon 129. The patient developed akinetic mutism at 16 months and died at 28 months after onset. The clinical presentation and neuroimaging findings were compatible with the vCJD cases reported since 1996, and met the World Health Organization Case Definition for probable vCJD. In this communication, we also review two other cases of vCJD in Asia. All three cases were assumed as imported cases from the UK because of the residential or travel history of the patients.;jsessionid=F842A68523935DD3B42E17DD8D525731.d01t01?systemMessage=There+will+be+a+release+of+Wiley+Online+Library+scheduled+for+Saturday+27th+November+2010.+Access+to+the+website+will+be+disrupted+as+follows%3A+New+York+0630+EDT+to+0830+EDT%3B+London+1130+GMT+to+1330+GMT%3B+Singapore+1930+SGT+to+2130+SGT

Incidence of Creutzfeldt-Jakob disease in Taiwan: a prospective 10-year surveillance

Chien-Jung Lu, Yu Sun and Shun-Sheng Chen

Abstract This study was performed to estimate the incidence of Creutzfeldt-Jakob Disease (CJD) in Taiwan from 1998 to 2007. Suspected cases of CJD were reported to the Taiwan Creutzfeldt-Jakob Disease Surveillance Unit, a nationwide, hospital-based case report system initiated since 1996 to prospectively conduct a CJD epidemiological study. Consecutive patients who met the diagnostic criteria recommended by the World Health Organization were enrolled. The clinical information of each suspected case was collected and case ascertainment was performed by an expert committee. A total of 123 sporadic CJD were identified without any iatrogenic or new variant CJD cases. The overall annual incidence rate (95% CI) was 0.55 (0.46–0.65) cases per million person-year. There was no statistically significant difference between the calendar year of disease onset (P = 0.97). The incidence rates were not significantly different between women and men (P = 0.63). Age was the main factor for the risk of CJD (P < 0.0001). Age-specific incidence rate increased after the age of 40 years with the peak being in the 70–79 years age group. Our data showed low annual incidence rate and high frequency of methionine homozygous prion protein genotype of sCJD in Taiwan. This report provided important epidemiological data on ethnic Chinese.

Taiwan advises against import of U.S. beef tongues

AIT Director defends tongues as without risk

Taiwan News, Staff Writer 2010-04-20 02:53 PM Fonts Size:

TAIPEI (Taiwan News) – In a surprise reversal of policy, the government told meat traders Tuesday it advised them against importing beef tongues, diaphragms and testicles from the United States, despite a claim by Washington’s top representative in Taiwan that they posed no threat to health. The government said inspectors would check each case of beef including tongues, diaphragms and testicles, instead of just the first case of each batch, as it had announced earlier.

“Consumers still have doubts about the safety of tongues and testicles, so it’s best not to import them,” said Kang Jaw-jou, director-general of Taiwan’s Food and Drug Administration.

The U.S. Department of Agriculture announced last week it would allow the export to Taiwan of hanging tenders, tongues, tails, penises, testicles, tendons, and diaphragms from cattle younger than 30 months or slaughtered since the beginning of the month.

While Taiwan agreed the imports were legal under a protocol both countries signed last October, there was still widespread doubt about the new products. Tongues could still pose a risk for bovine spongiform encephalopathy or mad cow disease, consumers groups and lawmakers said.

After first approving of the new products, government officials held a news conference Tuesday to announce they advised traders against importing the products for the time being, even though they would not impose a ban.

An importer who saw his application for 453 kilograms of U.S. beef products approved on April 15 decided to cancel his order, said Huang Chih-peng, the director-general of the Ministry of Economic Affairs’ Bureau of Foreign Trade, which reviews the applications.

Huang said he had personally talked to the company, which canceled its plan in a concrete response to health doubts.

Inspectors would also test each case or box of tongues and related products, and not just one case from each batch, the government said.

American Institute in Taiwan Director William Stanton said the beef products were completely safe. Some people would bring up the subject for political purposes, but this had nothing to do with health, he said.

Tongues had never been regarded as a risky part of cattle, and the protocol never banned the product, Stanton said. He rejected a statement by Vice Foreign Minister Shen Lyu-shun to the effect that last week’s decision by the USDA to allow the export of tongues was made unilaterally without consulting Taiwan.

The Office of the United States Trade Representative said Monday it was deeply disappointed with Taiwan’s decision to toughen up inspections because it was not consistent with the protocol.

Lawmakers accused the government of going against the Legislative Yuan’s January decision to ban the import of internal organs by agreeing to allow diaphragms and testicles.

William Lai of the Democratic Progressive Party said that the beef products were included under the section for internal organs during Taiwan-U.S. negotiations and therefore also fell under the Legislative Yuan ban.

Ruling Kuomintang lawmaker Tsai Chin-lung told reporters he did not dare eat the beef tongues and testicles because they were too risky. His KMT colleague Wu Ching-chih agreed and said the products should be banned.

North Dakota Firm Recalls Whole Beef Head Products That Contain Prohibited Materials


Congressional and Public Affairs (202) 720-9113 Catherine Cochran

WASHINGTON, April 5, 2010 - North American Bison Co-Op, a New Rockford, N.D., establishment is recalling approximately 25,000 pounds of whole beef heads containing tongues that may not have had the tonsils completely removed, which is not compliant with regulations that require the removal of tonsils from cattle of all ages, the U.S. Department of Agriculture's Food Safety and Inspection Service (FSIS) announced today.

Tonsils are considered a specified risk material (SRM) and must be removed from cattle of all ages in accordance with FSIS regulations. SRMs are tissues that are known to contain the infective agent in cattle infected with Bovine Spongiform Encephalopathy (BSE), as well as materials that are closely associated with these potentially infective tissues. Therefore, FSIS prohibits SRMs from use as human food to minimize potential human exposure to the BSE agent.
