Dutch authorities have said they are considering whether come quarantined poultry farms could resume operations in July.

Farms in the central Gelderland province, where the recent outbreak of avian influenza first emerged, would be the first to reopen as no new cases have been reported there since 7 April, Agriculture Ministry spokeswoman Martine de Haan told Reuters.

“We have to be careful because the manure is still on the infected farms, we are afraid there is still virus there…any repopulation would be in July at the earliest,” De Haan said.

Inspectors were also still tracking down and culling chickens on smallholdings, which had been responsible for some of the most recent cases.

Authorities were also considering whether or not to destroy stocks of animal feed on infected farms, De Haan said.
