The company is moving Brian Sikes into the role of chief executive officer.
Sikes has worked for the company for 31 years and was responsible for growing the meat protein side of the business.
Last year, he was appointed chief operating officer.
Sikes replaces David MacLennan (January 1st) who becomes executive chair.
The industry feels the move signifies Cargills plans to diversify and grow its business options putting more emphasis on the meat processing sector.
