(CNN) - After four decades of serving its ketchup, McDonald's is cutting ties with Heinz.
The fast food giant cites "recent management changes" as the reason for the switch.
Heinz recently hired the former CEO of rival Burger King.
In a statement, McDonald's Global Media Relations Director says Heinz represents only "a small percentage" of the company's condiment and sauce business.
McDonald's says it will transition to other suppliers.
The company suggests customers won't notice the change.
