How to Prevent Dirt from Getting Into your Milk when Milking
Even though a milker may be careful, small particles of dirt, hairs, etc., will fall into the milk pail. It is true that the milk is strained afterward, but a large percentage of the dirt dissolves and passes through the strainer along with the milk.
The best way to prevent this dirt from falling into the milk is to put a piece of cheesecloth over the pail opening, securing it there by slipping an open wire ring, over the rim. The milk will readily pass through the cloth without spattering.
