Food Safety: Theory And Practice, Author: Paul L Knechtges - StudyBlue

Since food-related diseases can be serious, or even fatal, it is important to know and practice safe food-handling behaviors to help reduce the risk of getting sick from contaminated food. Foodborne diseases are widespread throughout the world.

Healthy, or what can be termed as safe food, is food that has not lost its nutritional value, that is clean, in physical, chemical and microbiological terms and that is not stale. The factors causing the contamination of the food may threaten the safe consumption of it and thereby make the foods harmful to human health.
