Food safety and food hygiene are not to be confused with food hygiene and food safety! These terms are misused in common language: although food security is an expression that refers to the safety of food supplies in quantity and quality. Whereas, food safety is the assurance that food does not harm the consumer when prepared and/or consumed in accordance with its intended use. Examples of means implemented for food safety: control of origins, control of composition, detection of sources of bacterial contamination, control of the chain of manufacture or processing and control of the cold chain. However, food hygiene (dietetics) is a medical term referring to the reasoned choice of food (rules of nutrition and dietetics) and food hygiene (Food Hygiene) as for it, refers to all the conditions and measures necessary to ensure the safety and wholesomeness of food at all stages of the food chain
