The move follows similar news in the UK that Unilever is moving the creative duties on Hellmann's mayonnaise out of Lowe and into O&M without a pitch, as well as reviewing its Knorr business out of JWT.
Bill Gray, the co-chief executive of O&M, said in a statement: "Ragu is a great brand with terrific potential. It is especially rewarding for us to be given additional assignments based on our work for other Unilever brands."
