Swiss cheese hole mystery solved: It's all down to dirt
http://www.bbc.com/news/world-europe-32920200
Contrary to what cartoons have suggested over the years, the holes are not made by mice eating their way through the cheese.And nor are they produced by carbon dioxide released by bacteria, as popular scientific belief held.
Instead, a Swiss laboratory says they are created by flecks of hay.
Agroscope said the findings explained why fewer holes had been appearing in Swiss cheeses over the last 15 years, since more modern milking methods made it less likely for hay to fall into containers.
