Food hygiene and sanitation are two interrelated concepts that refer to the measures taken to ensure the safety and quality of food throughout its production, processing, storage, distribution, preparation, service, and consumption. They aim to prevent food contamination, spoilage, deterioration, adulteration, poisoning, infection, and intoxication that can cause harm to human health.
What is food hygiene and sanitation?
According to the World Health Organization (WHO), food hygiene is "the conditions and measures necessary to ensure the safety of food from production to consumption". It involves following good practices of personal hygiene, cleaning, disinfection, pest control, waste management, temperature control, cross-contamination prevention, allergen management, labeling, traceability, recall, etc.
Food sanitation is "the application of a system of measures designed to protect public health by preventing or reducing hazards that may arise from food". It involves applying scientific principles and methods to control microbial growth, chemical hazards, physical hazards, natural toxins, etc. It also involves complying with legal requirements and standards set by authorities.
Why is food hygiene and sanitation important?
Food hygiene and sanitation are important for several reasons:
They protect consumers from food-borne illnesses that can cause diarrhea, vomiting, fever, abdominal pain, dehydration, malnutrition, organ damage, disability, or even death.
They protect food businesses from legal liabilities, penalties, lawsuits, reputation damage, loss of customers, loss of revenue, or even closure.
They protect the environment from pollution, waste, resource depletion, or biodiversity loss caused by improper food handling and disposal.
They contribute to food security, food safety, food quality, food diversity, food availability, food accessibility, and food affordability for all.
