Food Safety Requirements

Because much of HACCP was included in ISO 22000, it’s important to understand a little bit of what HACCP is. HACCP could be defined as the system used to formally identify, evaluate, and control hazards that are significant to food safety.

HACCP activities require 12 very logical and straightforward steps: 
  1. Assemble the HACCP team that will ensure that the HACCP plan is properly completed and implemented. 
  2. Describe the product associated with the specific HACCP plan; organizations that produce multiple products may have several HACCP plans. 
  3. Identify the intended use of the product. 
  4. Construct flow diagrams showing the flow and steps associated with the product and process steps. 
  5. Confirm the flow diagram by direct investigation or observation, list all potential hazards associated with the flow, and conduct a hazard analysis to determine which hazards need to be controlled. 
  6. Identify and consider control measures that can be undertaken to prevent the hazard. 
  7. Determine the critical control points where controls will be put in place to ensure food safety. 
  8. Establish critical limits for each critical control point where acceptable levels are clearly defined. 
  9. Establish a monitoring system for each critical control point. 
  10. Establish corrective actions to be taken when critical limits have been exceeded. 
  11. Establish verification procedures to monitor results. 
  12. Establish documentation and record keeping to provide evidence of control. 

One of the differences between HACCP and ISO 22000 is the ISO standard’s emphasis of the use of prerequisite programs (PRPs). PRPs are generic controls used by any food business operation to maintain hygienic conditions in the processing environment. PRPs stipulate the preconditions necessary for producing safe food. Depending on the type of activity involved, the following defined requirements should be considered: 
  • Good Agricultural Practice (GAP) 
  • Good Hygienic Practice (GHP) 
  • Good Production Practice (GPP) 
  • Good Distribution Practice (GDP) 

Additional components of prerequisite programs include, for example, cleaning and sanitizing; pest control; personnel hygiene; construction and layout of buildings and associated utilities; supplies of air, water, energy, and other utilities; supporting services such as waste and sewage disposal; supplier control; employee training; and more. 

Organizations should consider adoption of ISO 22000 for three principle reasons: 
  1. Benefits in the marketplace. Customers receive confidence through the demonstrated implementation and ongoing maintenance of the system. As organizations along the supply chain adopt ISO 22000 or become subject to customer controls along the food supply chain, the market achieves assurance that there are no weak links in the food chain. 
  2. Benefits to the organization producing the food. The organization has confidence that it has done the right things to provide control over activities that affect food safety. The system is well-planned, monitored, audited (internally and externally), and measured, and feedback is provided in a timely manner to decision makers. 
  3. ISO 22000 goes well beyond regulatory requirements. ISO 22000 includes -but goes beyond- existing HACCP programs. HACCP programs are excellent and work very well to prevent food safety problems, but they are not supported by an overarching systematic approach that includes many of the components extracted from ISO 9001.

What Potential Users Should Know About ISO 22000

ISO 22000 works for all organizations regardless of their size. The standard outlines best practices that deliver results and convey confidence to the organization as well as its stakeholders. This confidence is demonstrated by the internal audit process and, in particular, the external audit process through ISO 22000 registration.

Failures in food safety practices are dangerous and expensive. It is obviously easier, less dangerous, and less expensive to prevent these problems before they occur.

ISO 22000 harmonizes various industry and national standards for food safety. Increasing requirements from customers and other stakeholders within the food chain demand increased rigor and demonstrated results. There is an increasing need to provide evidence of conformance to an internationally accepted and approved set of requirements.

If your organization participates in any part of the food industry, you will likely want to consider learning more about ISO 22000. A brief list of organizations that may need to consider ISO 22000 may include: 
  • Food manufacturers 
  • Producers of food ingredients 
  • Agricultural producers 
  • Transporters of raw or finished food products 
  • Storage facilities for raw or finished food products 
  • Packers 
  • Subcontractors within the food chain 
  • Retailers 
  • Wholesalers 
  • Producers of animal feed 
  • Food equipment manufacturers 
  • Food packaging manufacturers 

For a successful implementation of ISO 22000 you will need to create a clear project plan including the identification of responsibilities, tasks, and an associated timeline. Wherever possible, make use of what you are currently doing related to quality or food safety. It doesn't make sense to change something that’s working. 

You will need to communicate the purpose and benefits of ISO 22000 to employees. Be prepared to overcome the arguments, which are the same arguments encountered by any standards implementation: There’s too much paper, there’s too much complexity, it’s not appropriate for a small business, and/or the bar is set too high for the organization. 

Educate people on the technical aspects of ISO 22000 (i.e., auditing, creation of effective documents, food safety specific tasks, biological contamination, etc.).

Very good post, I was really searching for this topic, as I wanted this topic to understand completely and it is also very rare in internet, that is why it was very difficult to understand.
