Answer 2

Food preservation, any of a number of methods by which food is kept from spoilage after harvest or slaughter. Such practices date to prehistoric times. Among the oldest methods of preservation are drying, refrigeration, and fermentation. Modern methods include canning, pasteurization, freezing, irradiation, and the addition of chemicals. Advances in packaging materials have played an important role in modern food preservation.

Food protection methods are measures taken to protect food from being contaminated by any agent. All food must be protected at all times during storage and preparation from the following contaminants:

• any water that is not known to be safe, including overhead leaks and drips
• dirty hands
• coughing and sneezing
• dust and soot
• flies, rodents and other vermin
• insecticides and other chemicals
• unclean utensils and work surfaces
• cigarette smoke.

These factors either affect the food directly to make it unsafe (such as cigarette smoke or soot), or, like coughs and sneezes or insects, contaminate the food with microorganisms.

The same principles also apply in domestic situations. The importance of promoting good food handlers’ hygiene is:

• To prevent food contamination and spread of disease.
• To ensure the good health of people eating the food.
• To protect the health of the food handler.
