Manufacturer Narrative
A biomérieux internal investigation has been completed with the following results: a review of all data registered for the manufacturing and quality control departments of the lots 1007942830 (api listeria) and 1007922470 (zym b) did not highlight any issue. A review of all complaints did not show any issue with these lots. An internal quality control investigation of the api listeria strips was conducted using the customer's lot (lot a) and a second lot for reference (lot b). The investigation used three different lots of zym b reagent. Lot c was the lot used as reference and used by the customer without issue, lot d was lot related to the customer issue, and lot e was a lot used as reference and not used by the customer when he tested api listeria lot number 1007942830. Following an internal quality control procedure, the six (6) following associations (strips + reagents) were tested. Lot a + lot c, lot b + lot c, lot a + lot d, lot b + lot d, lot a + lot e, lot b + lot e. The results of the investigation were that all six associations tested (strips and reagent) with the listeria innocua strain atcc 33090 showed compliant results compared to the theoretical profile. In addition, the results were identical between the six associations tested, especially for the dim test which showed positive results on the six associations. The color intensity of the dim test was the same between the six associations tested. The customer issue was not reproduced. The api listeria batch (reference 10300 batch 1007942830) and the zym b reagent (reference 70493 batch 1007922470) are not defective.
 
Event Description
A customer in (b)(6) notified biomérieux of a quality control failure when testing a listeria innocua atcc 33090 strain associated with api® listeria 10strips+10media ¿ (ref. 10300, lot. # 1007942830)(complaint reported separately under medwatch 9615754-2020-00183) in association with the supplemental zym b x2 reagent¿ (ref. 70493, lot. #1007922470) (present report). The present report has been created following troubleshooting information, against the zym b x2 reagent lot that was tested in association with the api listeria strip. The customer noted that their normal procedure is that when they run out of the zym b x2 reagent that comes with the api strips that they use zym b x2 from these supplemental packages (ref. 70493). The customer stated that when testing listeria innocua atcc® 33090¿ strain, the quality control failed for the dim well giving a negative result instead of a positive result, which resulted in a misidentification of the quality control strain. They obtained an identification with the api system as l. Monocytogenes species instead of the expected identification of listeria innocua. The customer tested the api strips with other atcc strains for quality control with passing results for the following: listeria monocytogenes atcc® 7644¿; listeria ivanovi atcc® 19119¿; listeria grayi atcc® 25401¿. Zym b reagent (ref. 70493) is used in conjunction with api® listeria as a qualitative standardized system for the identification of listeria. It uses miniaturized tests as well as a specially adapted database. Inoculation and reading of the strip is performed manually and the identification is obtained using an identification software. The complete list of the organisms that are able to be identified by this system is given in the technical brochure - information for identification software.
