New bird flu case found in Friesland

A new case of avian influenza was discovered on a 22,000-hen poultry farm in Tzummarum, Friesland. The influenza is most likely a mild H7 variant, the Dutch government says. 

Because the low pathogenic, mild H7 variant can easily mutate into a high pathogenic variant, which is more contagious and deadly for chickens, European rules state that both virus possibilities need to be eliminated by culling the current hen population. The so-called depopulation will be performed by the Dutch Food and Consumer Product Safety Authority (NVWA).

A ban on transporting eggs, poultry, poultry manure and used bedding is in effect for all businesses within a one-kilometer radius of the farm. There is one other poultry farm within the isolated area and it is also being tested for the virus.

. The influenza case was quarantined on time and it did not spread on other poultry farms.
