ISO/TS 22002-1 Prerequisite Programmes on Food Safety

Technical Specification ISO/TS 22002-1 Prerequisite programmes on food safety — Part 1: Food manufacturing was first published in 2009. This technical specification effectively replaced Publically Available Specification (PAS) 220 Prerequisite programmes on food safety for food manufacturing which was published by BSI in 2008. Technical Specification ISO/TS 22002 is used in association with ISO 22000:2005 Food safety management systems - Requirements for any organization in the food chain by food manufacturers wishing to achieve FSSC 22000 certification. ISO/TS 22002-1 specifies the expected standard of prerequisite programmes which food manufacturers should implement in order to comply with ISO 22000 Clause 7 which requires prerequisite programmes to be established in order to assist in controlling food safety hazards.



  • Construction and layout of buildings and utilities
  • Layout of premises and workspace
  • Utilities
  • Supporting services including waste disposal
  • Suitability of equipment
  • Management of purchased materials
  • Measures for the prevention of cross-contamination

ISO 22002-1 specifies internal layouts should facilitate good manufacturing practices which provide protection against potential sources of contamination. There should be a logical flow of materials, products and personnel and segregation of raw and finished products. Walls and floors should resistant and capable of being cleaned. Ceilings and overheads shall be designed to prevent contamination. Openings should be screened. Equipment should be designed to facilitate good hygiene practices. Laboratory facilities should be sited and controlled to prevent product contamination. Microbiology laboratories should be away from manufacturing areas. Temporary structures should not encourage pests or pose a risk of product contamination. Storage facilities should allow segregation and provide protection from dust, condensation, drains, waste and minimize the risk of product contamination.


ISO 22002-1 section 6 covers utilities including air, water and energy in 6 subsections; general requirements, water supply, boiler chemicals, air quality and ventilation, compressed air and other gases, and lighting. The supply and distribution of utilities should minimize the risk of product contamination. Supplies should be monitored to ensure they are of adequate quality. An adequate supply of potable water should be available to ensure hygienic operation and adequate cleaning. Contamination of the supply with non-potable water should be prevented. Boiler chemicals should be approved and controlled. Air quality and ventilation should be controlled to prevent product contamination. As necessary air quality should be monitored. Compressed air and other gas systems should be constructed and maintained so that the gas filtered to remove dust, oil and water and is of adequate quality and to prevent product contamination. Lighting should be sufficient to facilitate hygienic operations and protected to prevent product contamination.


ISO 22002-1 section 7 covers waste disposal in 4 subsections; general requirements, containers for waste and inedible or hazardous substances, waste management and removal, and drains/drainage. Waste control systems should in place to ensure that waste is identified, handled, segregated, stored and disposed of in a manner which prevents contamination of products or production areas.


ISO 22002-1 section 8 covers equipment suitability, cleaning and maintenance in 6 subsections; general requirements, hygienic design, product contact surfaces, temperature control and monitoring equipment, cleaning plant, utensils and equipment, and preventative and corrective maintenance. ISO 22002-1 specifies the requirements for food contact equipment including the need for a hygienic design and construction which ensure that the equipment can be adequately cleaned and maintained. Food contact surfaces should be of compatible materials that are not affected by cleaning chemicals or the product. Thermal processes equipment should be designed to and meet the required process parameters in addition adequate monitoring equipment should be installed. All plant, utensils and equipment should be subject to a documented cleaning programme. Corrective and preventive maintenance programmes should be in place, particularly for equipment monitoring and/or controlling food safety hazards.


ISO 22002-1 section 9 covers the management of purchased materials in 3 subsections; general requirements, selection and management of suppliers and incoming material requirements. The purchase of materials which impact food safety must be managed to ensure that materials meet an appropriate specification. Supplier should be subject to approval and monitoring based on risk. Incoming materials should be checked to verify conformity prior to acceptance or use.


ISO 22002-1 section 10 covers measures for prevention of cross-contamination in 4 subsections; general requirements, microbiological cross-contamination, allergen management and incoming material requirements and physical contamination Measures to prevent physical, allergen and microbiological contamination should be in place. Areas with the potential for microbiological cross-contamination should be controlled and adequate segregation applied as determined by the risk. Allergens should be controlled and managed to prevent the cross-contamination of non-allergen products with allergens. Allergens when present in the product should be declared. Measures such as the control of glass and brittle materials, filtration and/or metal detection should be in place to prevent physical contamination.


ISO 22002-1 section 11 covers cleaning and sanitizing in 5 subsections; general requirements, cleaning and sanitizing agents and tools, cleaning and sanitizing programmes, cleaning in place (CIP) systems and monitoring sanitation effectiveness. Effective cleaning and sanitizing programmes should be implemented, validated and monitored to ensure that equipment and environment are maintained in a hygienic condition.
