Tyson's chief financial officer Wade Miquelon has left the company to take up a similar position at the US's largest pharmacy chain Walgreens.

Miquelon has accepted the post of CFO at Walgreens.

"We will miss the passion and strategic approach Wade brought to his job here at Tyson, but realize the move to Walgreens is a great opportunity for him and his family,'' said Dick Bond, president and CEO of Tyson Foods.

Tyson management will now begin the process of finding a replacement for Miquelon, who left Proctor & Gamble to join Tyson in April 2006.

Dennis Leatherby, who is Tyson's senior vice president of finance and treasurer, will assume Miquelon's responsibilities until the job is filled.

Miquelon will remain with Tyson until mid-June, completing his work on some strategic objectives and assisting with the transition process, the company said.
