For food safety, the CDC recommends proper fruit handling and preparation to reduce the risk of food contamination and foodborne illness.
Fresh fruits and vegetables should be carefully selected.
At the store, they should not be damaged or bruised and pre-cut pieces should be refrigerated or surrounded by ice.
All fruits and vegetables should be rinsed before eating.
This recommendation also applies to produce with rinds or skins that are not eaten.
It should be done just before preparing or eating to avoid premature spoilage.
Fruits and vegetables should be kept separate from raw foods like meat, poultry, and seafood, as well as utensils that have come in contact with raw foods.
Fruits and vegetables, if they are not going to be cooked, should be thrown away if they have touched raw meat, poultry, seafood or eggs.
All cut, peeled, or cooked fruits and vegetables should be refrigerated within two hours.
After a certain time, harmful bacteria may grow on them and increase the risk of foodborne illness.

There are special blessings for fruits, vegetables, bread and wine.
() There is also an all-inclusive blessing that can be used if one is unsure of what blessings to say.
The all-inclusive blessing should be used for all things which do not directly come from the earth, such as milk, fish and eggs.
If one has many different kinds of food of a given type to say blessings for, he or she may choose one food to say the blessing oven and the blessings said will suffice for all of the rest of the foods of that kind. 
 Pasteurization of milk and chlorination of drinking water destroy the organism.
Treatment with antibiotics can reduce fecal excretion.
Infected health care workers should not provide direct patient care.
Separate cutting boards should be used for foods of animal origin and other foods.
After preparing raw food of animal origin, all cutting boards and countertops should be carefully cleaned with soap and hot water.
Contact with pet saliva and feces should be avoided.
Following are recommendations of the World Health Organization.
Recommendations for the public and travellers Your food should be properly cooked and hot when served.
Consume only pasteurized or boiled milk and milk products, never raw milk products.
Make sure that ice is from safe water.
If you are not sure of the safety of drinking water, boil it, or disinfect it with chemical disinfectant.
Wash hands thoroughly and frequently with soap, especially after using the toilet and after contact with pets and farm animals.
Wash fruits and vegetables thoroughly, especially if they are to be eaten raw.
Peel fruits and vegetables whenever possible.
Recommendations for food handlers  Food handlers, professionals and at home, should observe hygienic rules during food preparation.
Professional food handlers should immediately report to their employer any fever, diarrhea, vomiting or visible infected skin lesions.  
William Hay contracted Bright's disease (or what modern medicine refers to as Nephritis).
Heart-dilated and near death, Hay began eating only natural foods; his calorie intake dropped and his health improved.
Hay spent the following decade studying naturopathy and food combining to reduce the acid end-product of digestion.
He found that fruits and vegetables produce an alkaline end-product when they are fully metabolized, while processed and refined foods left a high acidic environment after digestion.
His theories went on to encompass food-combining; whereas incorrect combination would cause even alkaline foods to leave a less desirable acidic digestion end-product.
The Hay System promoted the practice of eating three meals per day with meal one being alkaline foods only, meal two protein foods with salads, vegetables and fruit, and meal three comprising starchy foods with salads, vegetables and sweet fruit.
There should be an interval of 4.0 to 4.5 hours between each meal.
However, in 1935, Stewart Baxter showed that the pancreas secretes digestion enzymes simultaneously regardless of whether the food eaten is carbohydrates or protein.
The theory that carbohydrate and protein rich foods should be eaten separately is considered "unfounded" because it ignores the fact that carbohydrate rich foods all contain significant amounts of protein.
Eating protein separately from carbohydrates also tends to cause the body to burn the protein as an energy source rather than to build muscle.
American artist Man Ray was a notable follower of the Hay Diet.
