Do not adopt strange dogs and do not pet dogs.
Before eating fruit or raw vegetables, wash and peel them unless picked from the tree by yourself.
Do not eat food that is spoiled, smells or tastes badly or is flyblown or maggoty or full of bugs.
Do not eat food which is not sufficiently cooked. All smoked, dried or salt meats or fish, such as ham, bacon, sausage, dried beef, bloaters, salt mackerel or codfish, must be well cooked, as they may contain "Measles" or other worm eggs. Cooking kills the egg.
Do not eat food exposed on public stands to dust, flies, dirty hands, dirty water, dirty cans, or dirty glasses and buckets.
Do not allow flies to breed in dirt or other filth around the house, nor allow them to walk on your food. This is possible by burning, burying or otherwise removing the dirt or filth, and by using fly traps, "swatters" and fly paper.
Do not wet lead pencils with your spit.
Do not wet your fingers with spit when you deal cards or turn over pages of books or magazines.
Keep the teeth brushed and the mouth clean. Have decayed teeth repaired at once. Decayed teeth drop out and they cause abscesses, which may destroy the jaw bone or cause brain fever. Old snags give the stomach the germs of rotting, which cause dyspepsia.
