Pilgrim’s Pride is bidding for Hain Celestial’s protein business. Hain, run by CEO Irwin Simon, is in the process of selling Hain Pure Protein, its chicken and turkey division, to make its remaining snack food company more attractive to a buyer. Pilgrim’s Pride has made a preliminary offer for the business, which sells to Chipotle and Panera Bread. Final bids in the auction for the unit of the natural foods company are due in mid-July.
