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 con- 

 ditions 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 ^1 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.

BOTTLE AND CAP— PERFECT SCORE, 5. 

 Bottles should be made of clear glass and free from attached metal parts. Caps should 

 be sealed in their place with hot paraffin, or both cap and top of bottle covered with parch- 

 ment paper or other protection against water and dirt. Deduct for tinted glass, attached 

 metal parts, unprotected or leaky caps, partially filled bottles, or other conditions permitting 

 contamination of milk or detracting from the appearance of the package.
