A dramatic innovation in 1996 re-invigorated the rodent dairy industry. A group of Danish technicians, led by Dr S Hassel at the Copenhagen Institute of Agriculture, patented the automated rodent milking machine (ARM).
Since then rat cheese production has increased 700% worldwide, and affordable rat cheese is now within reach of many more people. Rat cheeses are made not only in France, but also in many other countries. English rat cheese is gaining popularity. And in Russia herds of Siberian udder-rats produce some of the finest cheeses outside France.
