The accreditation of food testing laboratories is a fairly recent development in an industry that has long been involved in safety testing and characterization. The ISO/IEC 17025:2017 standard, together with optional laboratory-specific quality requirements for life sciences, helps provide critical assurance to customers and the public at large that the food, feeds, and drug product testing performed in these laboratories has been to the highest standards. The process begins with the laboratory identifying the particular tests/procedures for which it wishes to be accredited, initiating proficiency testing arrangements covering these methods, and generating the necessary quality system documentation. Once all of the quality system elements are in place, an assessor with the appropriate technical background is identified and the assessment is scheduled. After undergoing the audit and responding to the deficiencies, with objective evidence of corrective actions, the laboratory is granted accreditation. While accreditation is valid for two years, additional actions/activities are also required during this period. Thereafter, unless there are extraordinary circumstances, onsite visits are limited to performing a renewal assessment every other year.
