Abstract

South Korea’s Ministry of Food and Drug Safety MFDS has been developing programs for the inspection and accreditation of food sanitation inspection institutions Food sanitation inspection institutions such as MFDS regional offices the Research Institute of Public Health and Environment and authorized private service providers in South Korea must participate in proficiency testing PT programs to comply with the Food Sanitation Act and MFDS Notification No 2012112 As the PT provider the MFDS annually plans various microbiological and chemical PT programs for foods cosmetics and pharmaceutical products in accordance with ISO/IEC 17043 The aim of this project was to evaluate the performance of microbiological PT programs to ensure the quality of their routine test results The test materials used were freezedried BioBalls from BTF Pty Ltd Homogeneity and stability were investigated to assess the adequacy of the selected test materials This project also contains data from interlaboratory comparisons organized by MFDS in 2011 and 2012 More than 50 laboratories attended the PT program and submitted their results Laboratory results were rated with zscores according to the international standard ISO 13528 The results from 2011 and 2012 revealed that all participating laboratories had similar levels of proficiency Most of the participants received a rating of “Satisfactory” Moreover the percentage of participants who received a rating of “Unsatisfactory” decreased from 35  in 2011 to 20  in 2012
