The U.S. has been on the lookout for avian influenza for years, and especially since H5N1 hopped from poultry to people in 2003 and spread to 16 countries.
We have watched it spread over in Asia. It was only a matter of time before it came to us on the flyways, Shere said. It showed up last fall, first in the form of H5N8,detail jersey real madrid 2014, and a few cases of H5N1 - a different strain from the virus affecting people in Asia and the Middle East.
Shere says officials warned farmers and large producers then to double down on biosecurity.
We saw it coming,chelsea soccer jersey youth, Shere said. We saw it in Washington, we saw it in Oregon. We said you better up your biosecurity; this thing is coming. .
We saw it in Washington, we saw it in Oregon. We said you better up your biosecurity; this thing is coming. And it came.
The that spread the virus are the dabbling ducks, which get infected as they float on water and nibble on food just under the surface. They don't necessarily get sick but can spread the virus in their droppings — which are dispersed even further in water.
That made for a bad combination in Minnesota, which has nearly 12,000 large lakes and countless smaller lakes and ponds.
If you have got migratory birds and they stop at different locations on open water,football shirt culture borussia dortmund, it is pretty easy to understand, Shere said. This virus can live in the water for up to 130 days.
And once one farm was infected, lateral spread took over. That's when the virus gets spread by other means - perhaps other wild birds carrying it on their feet, rodents carrying it on their feet,chelsea fc sweatshirt india, trucks carrying it on their tires, farm workers or contractors carrying it on their boots.
So you have a double whammy,new england patriots game jerseys, Shere said.
H5N2's affected commercial or backyard flocks in Iowa, Minnesota, North Dakota, South Dakota, Nebraska, Indiana,borussia dortmund shirt xxl, Missouri, Wisconsin, Kansas, Arkansas, Oregon, California,new kit manchester city 2012, Washington and Idaho.
Sniffer tests have found the virus in the soil just yards from uninfected farms,tottenham hotspur jersey designer, Shere says, so everyone must take care. Tests in Europe have suggested the virus can survive being blown short distances in dust.
We are just guessing that it's moving that way,spain national team training kit, Shere said There are some high winds in Minnesota, especially. It moves on a wet,arsenal t shirt custom, cold wind.
But people may be the most dangerous and persistent carriers, Jagne said. People coming in have to be closely scrutinized, she said.
Shere agreed. Let's be honest. The biosecurity is good, but it may not be complete, he said.
The biosecurity is good, but it may not be complete.
Perhaps workers aren't completely educated about how important it is to wash your hands and disinfect your boots, he added. If you don't know where that feed truck has been before it comes to your farm, you should, because it may just have left an infected premise.
It's expensive to do what it really takes to keep a virus out of poultry production facilities,new england patriots elite jersey, Shere says.
I heard of a farm today where they don't even allow folks to drive onto the farm,buy juventus shirt uk, he said. Workers must park, shower in a facility provided for them, change their clothes and get on a bus. Once on the farm, they shower and change again before entering their assigned buildings.
That is pretty good biosecurity, Shere said. We have to pull out all the stops. Even with the best biosecurity, we have to do better.
And while right now the biggest threat is to agriculture and to experts of chickens, the biggest fear is that the virus will change just enough to make it infectious to people. No people have been reported infected by this strain yet, but H5N1 and H7N9 have infected hundreds of people and any new avian influenza has the potential to mutate into a form that could become a pandemic.
