Tyson Foods Falls After Report of Suspected Bird Flu in Arkansas

Tyson Foods Inc., the largest U.S. chicken producer, fell the most in nine months after a report that a suspected case of bird flu had been found in the company’s home state of Arkansas.

Tyson fell 5.1 percent at 10:19 a.m. in New York, after declining 6.1 percent, the most since June 9. JBS SA unit Pilgrim’s Pride Corp., the second-biggest producer, fell as much as 9 percent and Sanderson Farms Inc. dropped as much as 5.3 percent.

A suspected case of avian influenza has been identified in poultry in Arkansas, Reuters reported citing the U.S. Department of Agriculture.

“No flocks grown for Tyson Foods have been diagnosed with avian influenza,” spokesman Worth Sparkman said in an e-mailed statement. “There are always biosecurity measures in place on poultry farms and we’ve been even more diligent since AI has been in the U.S. this winter.”
