NEW YORK -- Tyson Foods(TSN) - Get Report has dropped on bird-flu worries, but option traders are looking for the poultry producer to bounce. 

OptionMonster's Heat Seeker system detected the purchase of 7,500 March 37 calls on Friday, most of which priced for 85 cents to $1. Volume was above the previous open interest in the strike, which indicates that new money was put to work. 

Long calls lock in the price where investors can buy stock. That lets them gain from a rally with limited cost and benefit from potentially significant leverage if shares move higher.  

Tyson fell 0.37% to $37.42 on Friday and has lost 8% of its value in the last week. Most of that drop came after the U.S. Agriculture Department reported avian flu in the company's home state of Arkansas. Management said none of its birds were affected. 

Friday's total option volume in the name was triple its daily average for the last month. Calls outnumbered puts by a bullish 10-to-1 ratio.
