DES MOINES, Iowa (AP) — Bird flu has infected two more farms in Iowa, forcing the killing of 5.3 million hens and 88,000 turkeys, officials said Friday.
The new cases mean that across the nation, farmers have had to kill about 22 million birds, mostly egg-laying chickens but also including 1.8 million broiler chickens, 1.9 million pullet and other commercial chickens, and 1.9 million turkeys. Iowa accounts for many of those cases, with operations having to kill about 13 million chickens and 305,000 turkeys since the outbreaks began a month ago.
Iowa is the nation’s leading egg producer and had 46 million chickens on farms in February, according to U.S. Department of Agriculture data. Iowa raises about 11.7 million turkeys annually.
The latest cases were at an egg farm in Osceola County and a turkey farm in Cherokee County, both in northwest Iowa. Earlier this week, state officials also confirmed the virus on a turkey farm with 35,500 birds in Buena Vista County.
Because the virus is so infectious and deadly for commercial poultry, entire flocks are destroyed and composted on the farms when they are infected.
USDA data shows 23 states have confirmed cases in commercial or backyard flocks.
Spread of the disease is largely blamed on the droppings or nasal discharge of infected wild birds, such as ducks and geese, which can contaminate dust and soil. Infected wild birds have been found in at least 26 states, and the virus has been circulating in migrating waterfowl in Europe and Asia for nearly a year.
The Centers for Disease Control and Prevention said the cases in birds do not present an immediate public health concern. No human cases of the avian influenza virus have been detected in the United States. It remains safe to eat poultry products. Cooking of poultry and eggs to an internal temperature of 165 ˚F kills bacteria and viruses.
This story has been updated to correct the total number of birds killed in the U.S. to 22 million including all types and to correct the number killed in Iowa to 13 million instead of 18 million.
