MOUSE IN THE HOUSE
Them darn rodents still seem to be getting everywhere. They apparently love to reside in the insulation of a mushroom house. Then for recreation they scamper about among the bags or along shelves when no one's around – spreading disease all the while. If you're seeing green mould or Verticillium, or any of a number of diseases – then suspect a furry culprit. They are vicious little vectors.
