>> A strain of bird flu detected on a Tennessee chicken farm used by Tyson foods, the biggest chicken producer in the United States. The company saying on Sunday that it's working with state and federal officials to contain the virus, sorting through the more than 70,000 birds there and euthanizing some to stop the virus from entering the food system.
>> This particular virus that we've identified is, carries a high death rate or mortality rate in poultry. And it has little, if any, known risk to humans.>> In 2014 and 2015, the US killed nearly 50 million birds, mostly egg laying hens, during an outbreak of bird flu.
The losses pushed US egg prices to record highs and prompted international trading partners to ban imports of American poultry. On Monday, South Korea doing just that. Its agriculture ministry announcing it will cut off shipments from the U.S., its main chicken supplier, even during a current egg shortage as it deals with its own and worst ever bird flu outbreak.
The US Department of Agriculture saying the Tennessee discovery represents the first confirmed case of highly pathogenic H7 Avian flu in commercial poultry in the US this year. And it's the first time it's been found in that state. The last time this strain of bird flu was found in the US was in a commercial turkey flock in Indiana, in January of last year.
