In an industrialized society, every industry has a system of standards developed by experts to ensure the quality and safety of products. In the restaurant industry, QS is a certification that guarantees food quality and safety. The certification usually covers everything from the purchase of raw materials to all aspects of the production process, as well as storage and transportation, which are professionally tested and monitored to ensure food safety and health for consumers.

QS certification in the restaurant industry is not only a legal requirement, but also a reflection of the quality management of the enterprise itself. For the enterprise, the certification can improve customer trust, increase the attractiveness, and thus improve market competitiveness. For consumers, the certification means higher quality assurance, so that consumers can enjoy the food with confidence.

QS certification is a rigorous process with very high standards of scrutiny, regulating both health and safety and business activities. Typically, QS certification standards include: environmental hygiene in the kitchen, hygiene of waiters, quality of raw materials, and storage and processing of food. If a catering business wants to obtain QS certification, it needs to adjust to the standards and fully implement them into its actual operations. Subsequently, companies need to find the appropriate authority to review and certify in order to qualify for QS certification.
