I did something similar driving from France. It was in the car a while as I had a night in a hotel before a long drive to the port. The cheese had been in the travel fridge in my boot, but of course overnight in France the fridge wasn't running. At the port my car was stopped and briefly searched by the police there. He opened the boot, was hit by the smell of cheese, laughed and said he could smell I had been cheese shopping, then closed my boot. Good job he didn't carry on to find my stash of weed and the illegal immigrant.
