The extensive use of antiseptics or chemical preservatives in foods 

 and beverages is an evil that has for the past few years demanded the 

 attention of food officials. 



The knowledge that we have of the effect of these preservatives on 

 digestion and health tends to show that they are deleterious and that 

 their effect on the health of the consumer depends upon the quantity 

 and frequency of the dose. 



An investigation by the Bureau of Chemistry, United States De- 

 partment of Agriculture, has shown conclusively that the use in foods 

 of at least three of these chemical preservatives, viz., boric acid or 

 borates, salicylic acid or salicylates, sulphurous acid or sulphites, is 

 deleterious and dangerous to health. 



The investigation showed that boric acid or borates, when taken 

 into the body with food to the amount of four or five grains per day, 

 continued for some time, results in most cases in loss of appetite and 

 a feeling of fullness and uneasiness in the stomach, which in some 

 cases results in nausea, with a general tendency to produce a dull and 

 persistent headache. 



Regarding salicylic acid, the investigation showed that it is, when 

 used in foods, at first a stimulant, increasing the solubility and ab- 

 sorption of food elements from the alimentary canal. It soon, how- 

 ever, loses its stimulating effect and becomes a depressant, tending to 

 break down the tissues faster than they are rebuilt, to diminish the 

 weia'ht of the bodv and in some cases to result in illness. 



The results of the investigation were very decidedly unfavorable
