Possibly related to volcanic gases
Farmers around Höfn, on the South-East coast of Iceland, have reported numerous incidents of dead mice, that all seem to have died suddenly. This was reported by RÚV.
Farmers at Fornustekkir, a farm in the area, related the dead mice they encountered with the volcanic gases from the eruption around Bárðarbunga. Late October saw higher levels of sulphur-dioxide in the area than ever reported, shortly before the dead mice were found. Farmer Bjarni Sigurjónsson said that while herding, he and his companions ran into the mice lying around. “They were quite numerous, I have never seen as many dead mice at once.”
Interviewed by RÚV, farmer Kristín Jónsdóttir, at Hlíð, also in the vicinity, said that unusually high numbers of dead mice had been found in the area this autumn.
The Natural Research Institute of South-East Iceland says that possible explanations would include poisoned food or atmosphere. Now, they say, is too late for an autopsy to find out conclusively.
