Non - Alcohol drink book

The emphasis on food safety has led to the adoption of the HACCP (Hazard Analysis and Critical Control Points) system by food processors throughout the world. Adoption has been both voluntary and mandatory, as food regulatory agencies have moved to mandate the system for different prod-ucts. In the United States, HACCP has been mandated for the juice pro-cessing industry. Codex Alimentarius, the body aimed at developing guide-lines for international trade, has also adopted HACCP as part of its Code of Food Hygiene. In fact, if you talk to delegates to the Codex Committee on Food Hygiene, you will learn that HACCP literally ìsailedî through the Committee. Adoption of the system took only a few years, which is incredible when one understands that Codex is an organization in which change may take decades. HACCP is a system that was developed to ensure the safety of processed foods, so this leaves a great deal of the food supply ìuncovered.î Why do we say ìuncoveredî? We say it because HACCP is a system in which a food processor identifies potential hazards and builds ìcontrolsî into the process to eliminate, reduce, or control each hazard. With fresh produce, this is not © 2003 by CRC Press LLC realistic, as it is literally impossible to eliminate or control all potential hazards. Processes designed to destroy or control most pathogens would change fresh products so that they would no longer be fresh. Understanding this, representatives from industry, government, and academia took steps to remedy this deficiency. They developed what are now called Good Agricul-tural Practices or GAPs. The GAPs are a logical extension of HACCP into the fresh produce industry. They utilize HACCP principles and prerequisite programs to reduce the potential for product contamination and thereby ensure safety. Recent activities at the International Organization for Stan-dardization (ISO) further underscore the importance of food safety. ISO is in the process of developing food safety standards that address both HACCP and Good Agricultural Practices. 1 What is interesting is that many food processors who are buying produce are now mandating that the materials be purchased from growers who operate under GAPs. This applies even when the fresh products are being further processed. These companies operate under the theory that the application of GAPs will help to ensure the safety of their products, and thus protect their customers, business, and reputation.
