H.6.Investigation: this statement is to summarize findings on the recent complaint (b)(4) for bbl¿ chromagar¿ mrsa ii, catalog number 257435, lot number 1126698.Event description: it was reported that after a long hot transport mrsa and mssa strains did grow on the plates.Complaint history review: the complaints trends were reviewed for a period covering 12 months.There were no confirmed complaints received during that period on this product.Therefore, a trend could not be identified.Batch history record (bhr) review: the batch history review did not indicate any discrepancies.All release testing was satisfactory, and no deviations were observed.Sample analysis: pictures were provided showing plates with growth.An analysis of growth promotion for the media was performed on retention samples for batch 1126698.The performance tests on retention samples of the above mentioned batch resulted in excellent growth of the following strains: staph.Aureus mrsa atcc 33592, incubation time 20-22 hours at 35-37°c in aerob atmosphere.Staph.Aureus mrsa atcc 43300 incubation time 20-22 hours at 35-37°c in aerob atmosphere.The following strains resulted in complete inhibition, as expected: staph.Aureus mssa atcc 25923, incubation time 48 hours at 35-37°c in aerob atmosphere.Staph.Aureus mssa atcc 29213, incubation time 48 hours at 35-37°c in aerob atmosphere.Staph.Aureus mssa atcc 43387, incubation time 48 hours at 35-37°c in aerob atmosphere.No deviation could be detected on the retention samples regarding the performance of the media.Evaluation results: at this stage of our investigation, we have excluded any systemic failure in our production process.No deviation could be found during the qc performance test.Investigation conclusion: based on the evaluation of the report and based on the qc test results, the complaint was not confirmed.A corrective and preventive action will not be implemented as a trend could not be identified.We would suggest that to aside, and not use, any prepared plated media that does not meet the appearance specification as it is described on the bd certificate of analysis.This is consistent with industry recommendations for inspection of culture media prior to use (e.G.¿good practices for pharmaceutical microbiology laboratories¿, who technical report series, no.961, 2011, annex 2; chapter 1117 ¿microbiology best laboratory practices¿ the united states pharmacopeia; and the difco & bbl manual).
