ISO 22117 discusses proficiency testing in the microbiology of the food chain. ISO 22117 is an international standard for guidance in proficiency testing by interlaboratory comparison for the microbiology of the food chain.
ISO 22117 specifies requirements and guidelines for the organization of proficiency testing (PT) schemes for microbiological examinations of food and beverages, feeding animals, environmental samples from food and feed production and handling, and primary production stages.
ISO 22117 deals only with areas where specific or additional details are necessary for PT schemes dealing with microbiological examinations for the specified area.
ISO 22117 also applies to the microbiological examination of water where water is either used in food production or is regarded as food in national legislation.
ISO 22117 on guidance for proficiency testing is relevant to:
Proficiency testing is the determination of laboratory testing performance by means of interlaboratory test comparisons.
ISO 22117 guidelines assist in proficiency testing to meet certain criteria and testing programs (frequency, number of samples, number of repeats, etc.) to meet the requirements of the type of method used and commodity tested, to achieve the level of control required.
ISO 22117 assists in aiding laboratory accreditation in a general framework of quality management.
By adopting ISO 22117 the user can enhance the process of proficiency testing using interlaboratory comparison.
