Ensuring the highest standard of food quality is an absolute must for any organization involved in the service of food to the public. Hotel and catering companies, fast food restaurants, large-scale kitchens, retail sector, wholesalers, butcher shops and supermarkets – they all have very stringent requirements when it comes to food quality and hygiene. When food is not transported, stored, handled and prepared under proper conditions, quality suffers and profit drops. In other words, the cold chain must always be guaranteed as it is highly correlated to food safety and quality. Uninterrupted documentation of the cold chain temperature is required to keep food fresh and comply to hygiene requirements, particularly the HACCP regulations.
