The 5 affected piglets died and the remainder were destroyed. An infected wild boar had been found dead nearby earlier in the month. France established a 3 km radius protection zone and a 10 km radius surveillance zone and banned exportation of pigs and wild boars from the deparments of Moselle and Meurthe-et-Moselle to the rest of France as well as to other countries. Serology tests for CSF on 10 adjacent farms were negative. The last reported case of CSF in farmed pigs in France was in 1993. The USDA does not recognize France as being free of CSF.

Republic of Korea (South Korea), May 2002 -- The Republic of Korea (ROK) reported an outbreak of Pan Asian Type 0₁ FMD in swine in two locations less than 25 km apart. The first site, Anseong, is about 60 km south of Seoul and the second site, Jinchon, is about 25 km further south than Anseong. The last outbreak of FMD in the ROK was in April 2000 and was a different FMD serotype. The ROK established an at-risk zone of 3 km radius, a protection zone of 3-10 km radius, and a buffer zone of 10-20 km radius. As of June 28 the disease had spread and about 60,733 pigs, 240 cattle, 16 goats, 95 native Korean cattle, and 9 deer had been destroyed on affected farms and a further 59,856 animals in the 3 km at-risk zone. The USDA does not recognize the ROK as free of FMD and the United States imported no relevant live animals or animal products in the last 3 years.

Newcastle Disease

Newcastle Disease in Australia, May 2002 -- Virulent Newcastle disease, almost identical to the 1999 Mangrove Mountain isolate (Australia), was diagnosed near Meredith, in western Victoria approximately 75 km west of Melbourne. Only one farm was affected and the farm was quarantined on May 8, 2002. Movement controls were implemented and a restricted area of approximately 3 km and a control area of approximately 10 km were established around the affected property. There were no other commercial poultry farms within the restricted area, and only five broiler farms within the control area, all of which showed no evidence of ND. Destruction and disposal of 249,069 birds on the infected farm was completed by May 24, 2002. Newcastle disease was last detected in Australia in 1999.

Newcastle Disease in Japan, April 2002 -- Japan reported Newcastle Disease (ND) in a commercial chicken flock in Kamikita Gun, Aomori Prefecture. Control measures included disinfection of the infected premises, destruction and burial of the chickens, and placement of all commercial flocks within a 5-km radius of the infected farms under quarantine. A hobby pigeon flock of 88 birds in Toyota Gun, Hiroshima Prefecture was later found infected and similarly destroyed. In June, additional infected flocks were found in Ihara-city (Okayama Prefecture), Kagawa Prefecture, and Karita gun (Miyagi Prefecture).

Avian Influenza

AI in Chile, June 2002 -- Chile reported an outbreak of H7N3 avian influenza on a breeding farm in the Province of San Antonio, Fifth Region. All 540,000 susceptible hens died or were slaugtered. Surveillance also revealed a serologic reaction to H7N2 in two units of grandparent breeding hens located in the Sixth Region, however, there were no signs of infection or reduced production. Testing was begun to rule out avian influenza antibody contaminated biologics. A breeding turkey farm 4 km from the first farm diagnosed in San Antonio, Fifth Region, broke with H7N3 but also had a serologic reaction to H9N2. Of a population of 51,870 breeding turkeys, 19,776 in the affected sectors died or were slaughtered. The remaining sectors are under surveillance for AI. No explanation for the presence of 3 serotypes has been developed and the hypothesis of contaminated biological products is still under investigation. AI has not been previously diagnosed in Chile.

BSE in Israel, June 2002 -- A 10 year old Holstein cow which had been raised in Israel died two days after the onset of central nervous system signs and post mortem samples were positive for BSE. The cow was part of a herd of 1300. Israel banned the importation of meat and bone meal from the United Kingdom in 1988 and from all other countries in 1990. A BSE surveillance system was introduced in 1996 which tests adult downer cattle, suspect animals and random normal animals. This was the first case of BSE identified in Israel.

C. Other Diseases

United States

Chronic Wasting Disease in New Mexico, June, 2002 -- A mule deer from White Sands Missile Range tested positive for chronic wasting disease (CWD), causing the New Mexico State Department of Game and Fish to declare an animal health emergency, closing the state to importation of deer or elk. This is the first positive test for CWD in New Mexico. CWD has previously been found in Colorado, Wyoming, Nebraska, Wisconsin, South Dakota and Saskatchewan, Canada. The United States Departments of Agriculture and Interior have delivered to Congress a national plan for assisting states, federal agencies, and Native American tribes in controlling CWD. A joint working group was also formed to ensure a coordinated federal approach to assist with CWD response efforts.
