And it might be heading east.
It's not a pretty sight.
Mounds and mounds of carcasses have piled up in vast barns here in the northwestern corner of Iowa, where farmers and officials have been appealing for help to deal with disposal of such a vast number of flocks. Workers wearing masks and protective gear have scrambled to clear the barns, but it is a painstaking process. In these close-knit towns that include many descendants of the area’s original Dutch settlers, some farmers have resorted to burying dead birds in hurriedly dug trenches on their own land, while officials weighed using landfills and mobile incinerators.
Iowa, where one in every five eggs consumed in the country is laid, has been the hardest hit: More than 40 percent of its egg-laying hens are dead or dying. Many are in this region, where barns house up to half a million birds in cages stacked to the rafters. The high density of these egg farms helps to explain why the flu, which can kill 90 percent or more of a flock within 48 hours, is decimating more birds in Iowa than in other states.
