REPORT OF STATE DAIRY COMMISSIONER 419 



2. The butter shall obtain a score on the quality of not less than 

 93 points, 100 being perfect, on 75 per cent or more of the scoring. 

 A creamery obtaining a score on butter below 92, or a creamery that 

 has more than 25 per cent of its scoring below 93, shall forfeit its 

 right to the use of such trade-mark until such time as the creamery 

 is again in a position to meet the necessary requirements. 



3. All butter marked with the Iowa state mark shall comply with 

 the Iowa state standards and contain not less than 80 per cent of 

 butterfat, and shall contain less than 16 per cent of moisture. No 

 preservative, neutralizer or adulterant shall be added to butter or to 

 cream from which the butter is to be manufactured. 



4. Butter sold under said mark shall be manufactured from 

 cream, which has been pasteurized, either in the form of milk or 

 cream. Pasteurization shall consist in heating the milk or the cream 

 to a temperature of not less than 140 degrees F. and holding above 

 140 degrees F. for a period of not less than 20 minutes, or heating 

 the milk or cream to a temperature of not less than 180 degrees F. 

 when flash heat is applied. 



5. If the butter is solid packed in tubs, the tubs shall bear the 

 Iowa state mark on two opposite sides, the marks shall be placed 

 immediately below the upper hoop or hoops, said mark to be three 

 inches in diameter. In addition to the markings as stated, the top 

 surface of the butter shall bear an imprint of the said mark, this im- 

 print to be five inches in diameter and the imprint into the butter 

 shall be from one-sixteenth to one-eighth of an inch in depth. But- 

 ter in boxes either solid packed or in print, shall bear similar mark- 

 ings on both ends of the boxes as those placed on the outside of the 

 tubs. A similar imprint shall be made into the butter if solid packed. 



6. The date of manufacture of the butter shall be marked on the 

 outside of the tub or box close to the state mark, in letters not less 

 than one-half inch in height, the same being placed in the following 

 manner: 12 ; 5 The figure 12 designates the number of the month 



b ° ° 



the figure 6 designates the day of the month, and the figure 5 desig- 

 nates the number of the churning on that day. Thus for the above 

 markings the reading would be that the butter was manufactured on 

 the twelfth month, sixth day and was the product of the fifth churn- 

 ing. 



7. Parchments for print butter may be marked with the state 

 trade-mark. The size of such markings shall be two inches in diam- 

 eter. At this time the board does not require the marking of the 

 date on individual prints.
