LONDON, England -- A new wave of suspected bird flu cases was reported across Europe and Asia Wednesday as EU officials geared up to prepare for any human pandemic. Tests confirmed the deadly H5N1 bird flu strain in a second location in Romania's eastern Danube Delta region, a govenment official said Wednesday. The tests were carried out at an internation expert laboratory in Britain where most of the suspected samples from around Europe are being sent for verification. Romanian authorities have killed all farm birds in the area and finished disinfecting the areas, including people's houses and yards.Preliminary tests detected the H5N1 strain of bird flu in samples taken from a region south of Moscow where hundreds of birds died suddenly, the Russian Agriculture Ministry said Wednesday.If confirmed, the discovery in the Tula region, 200 kilometers (125 miles) south of Moscow, would mark the first time the lethal H5N1 strain decimating flocks in Asia has appeared in European Russia, west of the Ural Mountains. (Full story)The Chinese government reported that some 2,600 birds have been found dead of the H5N1 strain of bird flu in northern China's grasslands, according to The Associated Press.In Brussels, a European Union official said there is a suspicion of bird flu in Macedonia. The disease has already affected birds in at least two other European countries, Romania and Greece, as well as neighboring Turkey.Meanwhile, a U.N. agency warned that the risk of bird flu spreading to the Middle East and Africa has markedly increased following the confirmation of the Romanian and Turkish outbreaks.In Russia, hundreds of birds have died suddenly in a region south of Moscow, local media reported Wednesday, raising fears of a new outbreak of bird flu there. If confirmed, the discovery in the Tula region, about 125 miles south of Moscow, would mark the first time that the deadly virus has appeared in European Russia, west of the Ural Mountains.The dead birds in China were found in a breeding facility in Tengjiaying, a village near Hohhot, the capital of the Inner Mongolia region, the official Xinhua news agency reported. They were infected by the deadly H5N1 strain of the virus, Xinhua said. It did not give any further details."The epidemic is under control," Xinhua said.European Union officials said they were preparing to extend a ban on imports of pet birds and feathers from Siberia because of the bird flu.EU spokesman Philip Tod also said the EU executive would send experts to Greece to help identify bird the bird flu strain there. Health officials said they will also hold a simulation exercise of a flu pandemic by end of year to improve preparedness.However, the EU's disease control agency downplayed fears of bird flu spreading to humans on the continent. The agency gave two tips for people to minimize the risk of infection: do not touch dead or sick birds, and only eat well-cooked eggs or poultry. "The risk of infection for most people in Europe is close to zero," said Zsuzsanna Jakab, head of the European Center for Disease Prevention and Control. "If they follow these guidelines the risk is basically nonexistent," Jakab said at a news conference in Stockholm. Greek authorities began Wednesday the systematic disinfection Wednesday of a farm on a remote Aegean Sea island where a lone turkey was found to be infected with the deadly H5N1 strain.Tests on the Greek bird are being carried out at the European Union's laboratory in Weybridge, England, to determine if it was infected with the H5N1 strain, which has destroyed flocks and killed 60 people in Asia since 2003.The sample was sent to Britain late Tuesday and the full results are expected to be ready in about a week, though an announcement could come sooner.Late on Tuesday, Bulgaria banned the imports of live fowl, poultry products and eggs from Greece, as well as the transit transportation of poultry loads that have passed through the territories of Turkey, Greece, and Romania. A ban on poultry imports from Turkey and Romania was introduced October 10.Greece has banned the export of live birds and poultry products from Aegean Sea islands neighboring Oinouses, and said it would keep the measures in force until the results from the British laboratory were known.Union foreign ministers on Tuesday declared the spread of bird flu from Asia into Europe a "global threat" requiring international action. (Full story)The meeting issued a statement saying bird flu posed a serious, global health threat if it shifted from birds to humans and one that required "a coordinated international reaction." European Health Commissioner Markos Kyprianou told reporters that because the flu may be carried by migratory birds, other European countries could experience outbreaks.He warned that the 25 EU member countries do not have enough anti-viral drugs on hand to fight a human pandemic.The World Health Organization recommends that governments hold in reserve sufficient anti-viral drugs to treat 25 per cent of their populations. Kyprianou said "more than half" of the EU countries are not yet prepared. EU ministers met as 12 new cases of bird flu were discovered in Romania.(Full story)And samples from a dead bird were sent from Macedonia to London for testing after a large number of birds died in the city of Bitola near the border with Greece, a member of Macedonia's parliament said Tuesday.A U.N. agency warned Wednesday that the risk of bird flu spreading to the Middle East and Africa has markedly increased following the confirmation of outbreaks in Romania and Turkey. "One of our major concerns is now the potential spread of avian influenza through migratory birds to northern and eastern Africa," Joseph Domenech, Chief Veterinary Officer at the Rome-based U.N. Food and Agriculture Organization, said in a statement. "There is a serious risk that this scenario may become a reality," he said. The statement also mentioned the increased risk that bird flu could spread to the Middle East. Swiss drug maker Roche, pressed to raise output of antiviral flu drug Tamiflu, said it would consider allowing rival firms and governments to produce it under licence for emergency pandemic use. A Dutch company said it was working on a vaccine. Besides the human danger, countries visited by bird flu in its various forms can face face grave economic losses. The milder H5N7 strain struck the Netherlands in 2003, prompting slaughter of 30 million birds and losses estimated at 500 million euros.CNN Producer Stephanie Halasz contributed to this report Copyright 2005 CNN.
