Danish media say at least four containers have washed ashore and there may be 42 remaining in the North Sea.
The cleaning of Danish beaches has started. Refrigerators, medical supplies and other goods lost by a Maersk ship in the North Sea have washed up on the shore in recent days.
46 containers would have tipped overboard during a storm just before Christmas.
Danish media claim that at least four containers ran aground on the shore and there are perhaps 42 left in the North Sea.
The containers are drifting at sea on the stretch between Hanstholm and Skagen off the coast of the northern Jutland peninsula, according to the press.
For their part, local fishermen fear coming across containers or other debris.
Danish authorities did not clarify the circumstances of the event but confirmed that it took place during thestorm Pia.
