Food safety requires cleanliness, cooking the food thoroughly, refrigeration, and watching for dates of expiration on foods that will go bad.

The three keys to food safety are: proper hygiene practices (such as handwashing), thorough cooking of food to kill harmful bacteria, and safe storage temperatures to prevent spoilage and contamination.

Safe food would be food that does not contain physical, chemical or biological contaminants at levels that would be detrimental to health when consumed.
