ELEVENTH ANNUAL YEAR BOOK— PART IX 481 



ADULTERATED BUTTER. 



A few Iowa creameries have been called upon to pay a license and 

 fine for the manufacture of adulterated butter since the last report 

 was issued. Agents of the Internal Revenue Department are con- 

 stantly on the watch for butter containing more than sixteen per 

 cent of moisture and any creamery caught with adulterated butter 

 can have little hope of escaping the assessment. Every manufac- 

 turer should know just what kind of a product he is placing on the 

 market and with reasonable care on the part of the one making the 

 tests no trouble will be experienced. No prosecutions have been 

 undertaken by this department even where tests made have shown 

 butter to contain more than sixteen per cent of water. The Iowa 

 law requires that butter shall contain not less than eighty per cent 

 (by weight) of butter fat. With the Internal Revenue Depart- 

 ment fixing a limit of sixteen per cent water and the state law 

 requiring not less than eighty per cent of butter fat, butter low in 

 salt may be subject to seizure under the government ruling and yet 

 come well within the limit fixed by the state law. 



OLEOMARGARINE. 



The amount of oleomargarine manufactured in the United States 

 for the year ending June 30, 1910, was far in excess of any previous 

 year, being 141,862,282 pounds. 



This is about fifty-one million pounds more than was produced 

 last year and is sixteen million pounds more than was ever reported 

 in a single year even under the two cent tax. The various manu- 

 facturers of oleomargarine have been putting forth great efforts to 

 increase the sale of their product and have advertised their goods in 

 almost every locality. 



How well they have succeeded in their purpose is revealed by the 

 figures given above and oleomargine is now on sale in nearly every 

 town in Iowa. Even in the dairy districts some of the substitute is 

 being sold. 



Little trouble has been experienced on account of dealers not 



complying with the law relating to the handling of oleomargarine 



although in a few instances inspectors from this department have 



discovered consignments that had a yellow color in imitation of but-
