Byline: John Zarocostas in Geneva
THE return of the highly pathogenic avian flu in Asia, and findings of strains of the potentially lethal virus in pigs in parts of China, could spell trouble ahead for the multi-billion global market for poultry and pig meat, writes John Zarocostas.
On Friday, Dr Klaus Stohr, head of the World Health Organisation's global influenza programme, called on all avian flu-infected countries to step up surveillance of pigs in light of findings by researchers at China's Harbin Veterinary Institute that they isolated strains of the H5N1 virus in pigs from farms in parts of the country between 2003 and 2004.
'What is important now is not only China, but all infected countries step up surveillance in pigs,' Dr Stohr told reporters.
The WHO in a statement also warned, 'the co-circulation of avian, human and pig viruses in pigs is of significant concern because of potential genetic exchange, or 'reassortment', of material between these viruses.
'Such an occurrence has the potential to produce a new, pandemic influenza strain.'
