SANITARY CONTROL OF TOMATO-CANNING FACTORIES. 27 



condition reported that instead of having a shortage of suitable help 

 he had on file a waiting list which enabled him to fill any vacancies 

 on his force with selected help, although some factories near by were 

 finding it impossible to get sufficient help. 



The factory might well be regarded as a cooperative institution 

 and the employees made to feel that its welfare is a part of their 

 personal concern. Clean dressing rooms, clean, sanitary toilets, and 

 simple provisions for caring for emergency accidents will be ap- 

 preciated by nearly all the employees. But in order to attain such 

 an esprit de corps the superintendent or manager himself must be 

 foremost in planning and systematizing the work of cleaning, which 

 must be begun at the opening of the season and tactfully enforced 

 throughout the entire season if it is to prove successful. 



LABORATORY CONTROL. 



From the standpoint of law enforcement, laboratory methods of 

 examination are necessary, since there is no other way by which the 

 officials on whom rests the responsibility for enforcing the law can 

 judge correctly whether the product complies with the law's require- 

 ments. Without the check afforded by laboratory methods the 

 product of insanitary factories would come into open competition 

 with sound and good products, and in such condition that the con- 

 sumer usually would be unable to detect its true, offensive nature. 



Large manufacturers who have analysts thoroughly well-trained 

 in microscopical methods have also found laboratory supervision of 

 great value as a means of checking the work of their sorters and 

 superintendents. The fact that the character of their work can be 

 determined from an examination of the finished product is a strong 

 incentive toward inducing employees to exercise a greater degree of 

 care in the various details of manufacture. It is well also for the 

 analyst to check his work from time to time with that of other reliable 

 analysts in order to keep his own operations in agreement with those 

 of others in the same line. No conscientious analyst would undertake 

 to do careful analytical work for a manufacturer before he had 

 proved himself reliable through experience with the product and 

 through checking his findings with those of other analysts, known 

 to be reliable. 



The manufacturers also may test the ability of their analysts by 

 submitting to them sterilized portions of the same sample at dif- 

 ferent times under different identifying marks. It is of the utmost 

 importance, however, that the samples be exact duplicates, for if 

 they have not been taken from the same batch after thorough mixing 

 and then kept under sterile conditions the results are utterly worth- 

 less for purposes of comparison. It is the writer's belief that some
