    INVESTIGATION SUMMARY: EVENT DESCRIPTION: CUSTOMER COMPLAINS THAT SOME MICROORGANISMS¿ COLONIES GROW INDISTINGUISHABLE BETWEEN SPECIES ON PRODUCT NUMBER 254078. ACCORDING TO THE CUSTOMER, SPECIES OF SERRATIA, PROVIDENCIA, S. MALTOPHILIA AND MORGANELLA ALL LOOK COLORLESS WITH THE SAME MORPHOLOGY AND SIZE AND CANNOT BE DIFFERENTIATED ON THE AGAR PLATE. COMPLAINT HISTORY REVIEW: THE COMPLAINT TRENDS WERE REVIEWED. THERE WERE NO SIMILAR COMPLAINTS RECEIVED DURING THE PAST 12 MONTHS FOR LOT NUMBER 3073397. A TREND COULD NOT BE IDENTIFIED. BATCH HISTORY RECORD (BHR) REVIEW: THE BATCH HISTORY REVIEW DID NOT INDICATE ANY DISCREPANCIES AND ALL RELEASE TESTING WAS SATISFACTORY. SAMPLE ANALYSIS: AN ANALYSIS OF GROWTH PROMOTION FOR THE MEDIA WAS PERFORMED ON RETAIN SAMPLES FOR LOT 3073397. VISUAL INSPECTION OF THE RETAIN SAMPLES WAS WITHIN SPECIFICATION WITH THE MEDIUM HAVING A LIGHT PINK, SLIGHTLY OPALESCENT APPEARANCE. THE PERFORMANCE TEST WAS CONDUCTED ACCORDING TO OUR QC RELEASE TESTING PROCEDURE USING E. COLI ATCC 25922 AND P. MIRABILIS ATCC 12453 AND ADDITIONALLY USING S. MALTOPHILIA ATCC 13637. GROWTH OF ALL STRAINS WAS SATISFACTORY WITH COLONY COLORS BEING PINK FOR E. COLI AND COLORLESS / BEIGE FOR P. MIRABILIS AND S. MALTOPHILIA. RETURN SAMPLES WERE NOT PROVIDED. HOWEVER, THE CUSTOMER SHARED PICTURES ILLUSTRATING THE ISSUE. EVALUATION RESULTS: AT THIS STAGE OF THE INVESTIGATION, ANY SYSTEMIC FAILURE IN THE MANUFACTURING PROCESSES CAN BE EXCLUDED. NO DEVIATION COULD BE FOUND DURING THE QC PERFORMANCE TEST DURING INITIAL RELEASE TESTING AND DURING THE RETAIN SAMPLE TESTING. GROWTH OF E. COLI ATCC 25922, P. MIRABILIS ATCC 12453 AND S. MALTOPHILIA ATCC 13637 WAS SATISFACTORY. WITH MACCONKEY II AGAR, DIFFERENTIATION OF ENTERIC MICROORGANISMS IS ACHIEVED BY THE COMBINATION OF LACTOSE AND THE NEUTRAL RED PH INDICATOR. COLORLESS OR PINK TO RED COLONIES ARE PRODUCED DEPENDING UPON THE ABILITY OF THE ISOLATE TO FERMENT THE CARBOHYDRATE. AS STATED IN THE IFU, E. COLI AS A LACTOSE-FERMENTER IS EXPECTED TO GROW WITH PINK COLONIES WHEREAS NON-LACTOSE-FERMENTERS LIKE P. MIRABILIS GROW WITH COLORLESS / BEIGE COLONIES. THE SAME WOULD BE EXPECTED FOR OTHER NON-LACTOSE-FERMENTERS LIKE, PROVIDENCIA SPP., MORGANELLA SPP. AND S. MALTOPHILIA. SERRATIA SPP. ARE CATEGORIZED AS LATE LACTOSE FERMENTERS. THEREFORE, DUE TO SLOW FERMENTATION, COLONIES MIGHT INITIALLY APPEAR COLORLESS, HOWEVER, MAY BECOME RED-PIGMENTED, ESPECIALLY IF THE PLATE IS LEFT AT 25°C. IN OUR RETAIN SAMPLE TESTING USING E. COLI ATCC 25922, P. MIRABILIS ATCC 12453 AND S. MALTOPHILIA ATCC 13637, COLONY MORPHOLOGY AND COLOR WERE SATISFACTORY FOR ALL TESTED STRAINS AND A PROBLEM WAS NOT DETECTED. SINCE NO TREND WAS IDENTIFIED, NO CORRECTIVE PREVENTIVE ACTION WILL BE IMPLEMENTED THIS TIME. PLEASE NOTE THAT THE MEDIUM COLOR OF CATALOG NO. 254078 IS SPECIFIED AS ¿LIGHT PINK, SLIGHTLY OPALESCENT¿ ON THE CERTIFICATE OF ANALYSIS. COLOR OF THE MEDIUM CAN BE AFFECTED BY TEMPERATURE CHANGES DURING TRANSPORT OR STORAGE AND FUNCTIONALITY OF PLATES CAN BE IMPAIRED IF MEDIUM COLOR IS NOT WITHIN SPECIFICATION. WE RECOMMEND NOT TO USE ANY PREPARED PLATED MEDIA THAT DOES NOT MEET THE APPEARANCE AND PERFORMANCE SPECIFICATION AS IT IS DESCRIBED ON THE CERTIFICATE OF ANALYSIS. INVESTIGATION CONCLUSION: BASED ON THE RESULTS OF THE PERFORMED GROWTH PROMOTION TEST USING THE RETAIN SAMPLES, WE CANNOT REPRODUCE THE COMPLAINT ISSUE. BASED ON THE LAB RESULTS, THE COMPLAINT CANNOT BE CONFIRMED. A DEFINITE ROOT CAUSE HAS NOT BEEN ESTABLISHED. THIS MDR IS BEING SUBMITTED AS PART OF A RETROSPECTIVE REVIEW OF RECORDS DATING APRIL 2023-2025, UNDER CAPA 11910483.
