An important precautionary measure consists in the supervision of the food. The abattoirs and dairies should be placed under the supervision of practical physicians, and the sale of products derived from tuberculous cattle be prohibited. This refers to the milk in the first instance. Tuberculous cows should be excluded from dairy-farms. Raw milk should be avoided as much as possible as boiled milk has the same value.
The meat inspection must be strictly conducted especially with reference to tuberculosis in the case of beef, pork and chickens. Sheep are not subject to tuberculosis.
The associations of children in school and on the play-ground should be watched; do not let them visit in strange families before making thorough investigation as to their sanitary relations.
The health of servant girls should receive greater attention than formerly, as the disease is often carried into the house by them as investigation has proven.
In the schools and kindergartens the teacher ought to insist that children do not spit on the floor or in the handkerchief; in case of necessity he should keep sick children out of school and he should especially follow these precautionary measures as regards his own person.
The cleaning of the floor of a room should always be done in a damp way.
Moving into another house it is advised to rub down the walls with fresh baked bread.
As regards societies, every society and every health resort without exception and if possible every hospital should be obliged to have its own apparatus for disinfection and to make extensive use of it. Smaller societies may unite to procure an apparatus of the kind.
Especial attention should be given to the sprinkling of the streets during the dry season.
The state and the larger congregations should make it a point to maintain institutions for consumptives, beyond the city limits if possible, a healthy location in the country preferred.
