Above 200,000 0. 
Note. — When the number of bacteria per cubic centimeter exceeds the local 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 conditions 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 the 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.
