What Is Food Safety? Understanding the Essentials
Food safety refers to the systems, rules, and daily practices used to ensure food is safe to eat. For food businesses, this means controlling hazards at every stage.
Food safety is about preventing foodborne illness by controlling hazards. For a clear overview of why food safety matters worldwide, the WHO has an accessible fact sheet.
If you’re new to food hygiene, our introductory guide to Food Hygiene | Training | Regulations is an excellent starting point.
The 4 Cs of Food Safety
The 4 Cs are the core principles recognised by the Food Standards Agency (FSA):
Cleaning – Effective cleaning and disinfection prevent harmful bacteria from spreading.
Cooking – Food must be cooked to safe temperatures to destroy bacteria.
Chilling – Correct refrigeration slows bacterial growth. For more details, see our article on Food storage temperatures.
Cross-contamination prevention – The number one cause of food poisoning. Our in-depth guide on Which colour chopping board? explains how to separate raw and ready-to-eat food effectively.
Understanding these basics helps you reduce risks, protect customers, and meet legal standards.
