SOURING OF MILK
Do you believe that thunderstorms cause milk to sour? It is generally believed they do. The souring of the milk is generally attributed to the electrical action between the clouds which is responsible for the lightning associated with thunderstorms. 'There is no relationship between these electrical discharges and the souring of milk. Some authorities report that electricity will, destroy bacteria or retard their growth. In such cases electrical action would cause milk to keep longer. Souring of milk is caused by a growth of bacteria which feed upon the milk sugar and convert it into an acid when the milk is held at a warm temperature. The acid sours the milk.
It is believed that the temperature conditions immediately preceding a thunderstorm cause the souring of milk. Thunderstorms usually follow a period of hot, humid weather. The heat and humidity cause the refrigerators, cellars, and cooling tanks to become warm. The milk is also made warm, stimulating a rapid growth of bacteria, which really cause the milk to sour.
