- Abstract:
- Proficiency testing (PT) results from PT schemes in Salmonella sp. detection in octopus powder (ICSM-2022-01), and in shrimp powder (ICSM-2023-01) were described. Participants’ performance was assessed based on accurate determination of presence or absence of the target organism. Reported results from all 29 participants in ICSM-2022-01 achieved 93.10% sensitivity and 86.21% specificity. Out of 29 laboratories, 23 received satisfactory evaluation while six received unsatisfactory evaluation. In ICSM-2023-01, reported results from all 28 participants obtained 96.43% sensitivity and 78.57% specificity. Of the 28 laboratories, 21 received satisfactory rating while seven received unsatisfactory rating. In both PT rounds, three laboratories had repeatedly received unsatisfactory rating mainly due to false positive results. Possible sources of errors might be from cross-contamination and/or confusion during confirmatory tests. Laboratories with unsatisfactory performance were advised to conduct root cause analysis and corrective action, if necessary.
