DIRECTIONS FOR SCORING 



BACTERIA PER CUBIC CENTIMETER PERFECT SCORE, 35 



NOTE. When the number of bacteria per cubic centimeter exceeds the local legal limit 

 the score shall be 0. 



FLAVOR AND ODOR PERFECT SCORE, 25 



Deductions for disagreeable or foreign odor or flavor should be made according to condi- 

 tions found. When possible to recognize the cause of the difficulty it should be described 

 under Remarks. 



VISIBLE DIRT PERFECT SCORE, 10 



Examination for visible dirt should be made only after the milk has stood for some time 

 undisturbed in any way. Raise the bottle carefully in its natural, upright position, without 

 tipping, until higher than the head. Observe the bottom of the milk with the naked eye 

 or by the aid of a reading glass. The presence of ihe slightest movable speck makes a 

 perfect score impossible. Further deductions should^be made according to the amount of 

 dirt found. When possible the nature of the dirt should be described under Remarks. 



FAT IN CREAM PERFECT SCORE, 20 



If 20 per cent fat or above, score perfect. Deduct 1 point for each one-half per cent fat 

 6 NOTE.' When the per cent of fat is less than the local legal limit the score shall be 0.
