110 MODERN DAIRY PRACTICE. 



clothes properly clean for a whole week, no matter how 

 careful a person may be. The only sensible rule in regard 

 to the changing of wearing apparel is that clothes ought 

 to be replaced by clean ones as soon as they become slightly 

 soiled. It is in my opinion necessary that factory hands 

 should have clean clothes every day and every hour in the 

 week, and not only at the beginning of the week. 



A great difference may, as a rule, be observed between 

 men and women working in creameries in regard to out- 

 ward appearance. We often find that the men are negli- 

 gent as to cleanliness in wearing apparel, etc., a condition 

 which not seldom has led to sad results as regards the 

 butter and cheese product. It is of course true that the 

 fact that neatness in outward appearance is observed is no 

 guarantee for cleanliness in general; but, on the other hand, 

 it is always difficult, almost impossible, for a person 

 negligent about his looks to observe cleanliness in other 

 directions. It does not involve so much expense for factory- 

 hands always to appear in white and clean aprons, sleeves, 

 and caps, for while laundry expenses are increased, the rest 

 of the clothes are protected by their use. 



Necessity of Clean Hands. The attention of dairy and 

 factory workers may furthermore be called to the necessity 

 of keeping their hands carefully clean, as these very often 

 come in contact with the milk, cream, and especially the 

 butter. I found the following custom prevailing at a 

 margarine factory in France: Before beginning work in 

 which the men came in near contact with the milk or 

 its products they had to present themselves before the 

 superintendent, who then strictly examined them as to 

 cleanliness, especially their hands.
