France's largest poultry producer, LDC, warned on Friday that an upsurge in bird flu cases in the southwest might lead to the virus spreading to the country's major producing regions that were ravaged by it last year.
Avian influenza, commonly called bird flu, killed hundreds of millions of birds globally last year, disrupting supplies. Though there have been no documented cases of human-to-human transmission, countries must prepare for any change in the H5N1 virus's behaviour, the World Health Organization has said.
