One of the members of the co-operative, in the Jura region which is known for its distinctive cheese and wine, discovered the theft on Tuesday morning, when he arrived with a delivery of milk.
Police believe that a number of people must have been involved in the theft since the cheeses weigh 40 kg. And they seem to have chosen their get-away vehicle with care, ensuring that it was able to transport the booty.
The co-operative has already been robbed twice, but previously of cash rather than goods.
Police, who are trying to track down the criminals, say that there has recently been a rise in the number of robberies of cheesemakers in the Jura and Doubs region.
