Medical device brand name: bd bbl¿ chromagar¿ orientation and bbl¿ trypticase¿ soy agar w/5% sheep blood (tsa ii)-i plate¿.Investigation summary: during manufacturing of material 222239, media is formulated and sent through a high temperature short time sterilizer to remove bioburden.The petri dishes are subjected to uv radiation to decrease bioburden.The petri dishes are filled in a positive pressure hepa filtered environment.The filled plates are cooled and immediately wrapped into sleeves to decrease the introduction of microbes.Sleeves are then packaged into cartons and then transferred to a refrigerated truck (2 to 8 degrees c) for shipment to the distributor.Bd distributors are provided with the storage guidelines for the shipping and handling of bd media of 2 to 8 degrees c in a dark place.The main component of prepared plated media is purified water.The purified water is held in an agar matrix in the media.Release of the purified water as the matrix contracts during temperature cycling and progression through shelf life is referred to as exudation.As media progresses through shelf life, some condensate will appear inside the sleeves, dishes or on the agar surface.This condensate or excessive moisture occasionally presents upon removal from storage and packaging.Plates can be inverted over the lid and allowed to dry before inoculation when condensate/excessive moisture is noted.It is best to do these 2 to 3 hours directly before you inoculate the plates (see warnings and precautions section of your product insert where applicable).Control of the temperature cycling that our product experiences while in your possession may help reduce the amount of free moisture seen.Pooling of water inside the sleeve is not considered a normal amount of excessive moisture.If this is observed at your site, please contact technical services and document the occurrence with photographs as soon as possible after it is noticed.The batch history record for batch 1106169 was satisfactory at time of release and no quality notifications were generated during manufacturing and inspection.The release testing that is performed on this product does include physical attribute and bioburden testing.Sample plates are incubated at 25 degrees c and at 35 degrees c for approximately 72 hours.They are tested for physical attributes prior to release to ensure that they conform to typical levels.All physical attribute and bioburden testing performed on this batch was satisfactory per our internal procedures.The plates in question are not sterile.They are tested for bioburden prior to release to ensure that they conform to typical levels.However, this does not ensure that the end-user will not receive a contaminated plate.The complaint history was reviewed, and three other complaints have been taken on this batch for contamination including two others from this customer for different shipments ((b)(4)).Retention samples from batch 1106169 were not available for inspection.One photo was received for investigation of this complaint.The photo shows three sleeves from batch 1106169 with one sleeve that has blue in the chromagar orientation medium of one plate presumably due to growth in the medium.No condensation or free moisture is seen in the sleeves in the photo.Returns from batch 1106169 were received for (b)(4) and contamination was observed and identified as pseudomonas fluorescens and serratia liquefaciens.Excess moisture was not observed in those returns.Bd will continue to trend complaints for defects.The complaint can be confirmed for contamination.Capa # (b)(4) (corrective and preventative actions) has been initiated to determine the root cause and corrective actions of the contamination.
