Minnesota Declares Bird Flu Emergency

(Reuters) - Iowa Governor Terry Branstad declared a state of emergency on Friday due to a rapidly expanding avian flu outbreak, soon after state agriculture officials announced four new poultry farms had initially tested positive for the virus.

Iowa, the top egg-producing state in the United States, is the third state to declare a state of emergency because of the viral outbreak, which either has led or will lead to the extermination of up to 21 million chickens and turkeys nationwide.

Minnesota and Wisconsin declared states of emergency in April.

Iowa governor declares state of emergency due to bird flu outbreak
This undated handout image provided by Science and the University of Tokyo shows infectious particles of the avian H7N9 virus emerging from a cell. Scientists who sparked an outcry by creating easier-to-spread versions of the bird flu want to try such experiments again using a worrisome new strain. Since it broke out in China in March, the H7N9 bird flu has infected more than 130 people and killed 43. Leading flu researchers say that genetically engineering this virus in the lab could help track whether itâs changing in the wild to become a bigger threat. They announced the pending plans Wednesday in letters to the journals Science and Nature. (AP Photo/Takeshi Noda/University of Tokyo, Science)

Iowa's state of emergency is effective immediately now and will be in force until at least the end of May, depending on developments in the outbreak, Branstad told a news conference.

The measure expands the efforts of the state's emergency response plan, and authorizes various state entities access to additional resources, supplies and equipment to track and contain the influenza outbreak. It also allows for the removal and disposal of infected animals on either public or private lands and lifts weight restrictions on trucks hauling culled flocks, among other things.

In addition, the action allows the state and local law enforcement to set up checkpoints and road blocks anywhere in the state, including areas outside of quarantined farms, "in order to stop the spread of this contagious disease," according to the governor's proclamation.

Dozens of countries have imposed total or partial bans on U.S. poultry and poultry imports since the outbreak of avian influenza was discovered in December.

As of Friday afternoon, Iowa officials said, 21 farm sites in 10 Iowa counties had been identified as having either confirmed or presumed positive cases of the highly pathogenic H5 strain of bird flu.

The tally includes the nine Iowa farms that tested positive in the past 24 hours, including a commercial egg operation housing up to 5.5 million birds in Buena Vista County, and a separate egg-laying farm that houses 1 million birds in Madison County, according to Iowa's agriculture department.

So far, an estimated 16 million egg-laying chickens in Iowa are in infected or presumed infected farm facilities - meaning that at least one-quarter of the state's flock will have to be killed and disposed of, state officials said.

"While the avian influenza outbreak does not pose a risk to humans, we are taking the matter very seriously and believe declaring a state of emergency is the best way to make all resources available," Branstad said in a statement.
