We give sufficient conditions on Banach spaces E and F so that their projective tensor product $E ⊗ _π F$ and the duals of their projective and injective tensor products do not have the Dunford-Pettis property. We prove that if E* does not have the Schur property, F is infinite-dimensional, and every operator T:E* → F** is completely continuous, then $(E ⊗ _ϵ F)*$ does not have the DPP. We also prove that if E* does not have the Schur property, F is infinite-dimensional, and every operator T: F** → E* is completely continuous, then $(E ⊗ _πF)* ≃ L(E,F*)$ does not have the DPP.
