380 MAN'S IMPROVEMENT OF HIS ENVIRONMENT 



Inspection of Food Supplies. — In a city certain regulations for 

 the care of public supplies are necessary. Foods, both fresh and 

 preserved, must be inspected and rendered safe for the thousands 

 of people who are to use them. All raw foods exposed on stands 

 should be covered so as to prevent insects or dust laden with 

 bacteria from coming in contact with them. Meats must be in- 

 spected for diseases, such as tuberculosis in beef, or trichinosis in 

 pork. Cold storage plants must be inspected to prevent the keep- 

 ing of food until it becomes unfit for use. Inspection of sanitary 

 conditions of factories where products are canned, or bakeries 

 where foods are prepared, must be part of the work of a city in 

 caring for its citizens. 



Care of Raw Foods. — Each one of us may cooperate with the 

 city government by remembering that fruits and vegetables can 

 be carriers of disease, especially if they are sold from exposed stalls 

 or carts and handled by the passers-by. All vegetables, fruits, or 

 raw foods should be carefully washed before using. Spoiled or 

 overripe fruit, as well as meat which is decayed, is swarming with 

 bacteria and should not be used. 



An interesting exercise would be the inspection of conditions 

 in your own home block. Make a map showing the houses on the 

 block. Locate all stores, saloons, factories, etc. Notice any cases 

 of contagious disease, marking this fact on the map. Mark all 

 heaps of refuse in the street, all uncovered garbage pails, any street 



stands that sell uncovered 

 fruit, and any stores with 

 an excessive number of 

 flies. 



In addition to food in- 

 spection, two very impor- 

 tant supplies must be ren- 

 dered safe by a city for its 

 citizens. These are milk 

 and water.
