“It’s not my fault”
Mice are relief, finally. For years they have been accused causing the holes from nibbling away inside wheels of Swiss cheese.
After 100 years of research, scientists at the Swiss laboratory Agroscope have announced they have discovered the real reason Swiss cheese has holes in it. The holes are caused by hay — microscopically small specks of hay — that fall into the milk pails.
They say that fewer holes have been appearing in recent years because under modern miking methods less hay falls into the milk pails.
