And if you have an infection on your hand, be sure to bandage or cover it before preparing food. Keep all kitchen surfaces meticulously clean Since foods are so easily contaminated, any surface used for food preparation must be kept absolutely clean. Think of every food scrap, crumb or spot as a potential reservoir of germs. Cloths that come into contact with dishes and utensils should be changed frequently and boiled before re-use. Separate cloths for cleaning the floors also require frequent washing.
Animals frequently carry pathogenic microorganisms which cause foodborne disease.
Storing foods in closed containers is your best protection. Safe water is just as important for food preparation as for drinking. If you have any doubts about the water supply, boil water before adding it to food or making ice for drinks. Be especially careful with any water used to prepare an infant's meal. The World Health Organization regards illness due to contaminated food as one of the most widespread health problems in the contemporary world.
