The following fields were updated due to additional information: device available for eval yes, returned to manufacturer on: 2021-05-10 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 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)(6)).Retention samples from batch 1106169 were not available for inspection.Nine photos were received for investigation.One photo shows 11 unopened sleeves from batch 1106169.Four photos each shows a close up of the side of a sleeve with cracks in the sides of the lids visible.The other four photos each shows the side of a sleeve from batch 1106169 with a darkened agar bed highlighted in the medium.The darkening of the medis is presumably from growth even though colonies are not directly observed.Returns also were received for investigation.Forty plates from batch 1106169 were returned as ten loose plates held together with a rubber band in a ziplock bag and three unopened sleeves shipped in a box.A carton label from batch 1106169 (carton number 0137) also was included.Plates were inspected and surface and subsurface bacterial growth were observed in 4/40 plates returned and 25/40 plates had cracked lids (time stamps 0942, 0945, 0955, 0958, 0959) one affected plate was submitted to the id lab and pseudomonas fluoresens and serratia liquefaciens were identified.Bd ships product in temperature controlled trucks to distribution centers.Distribution centers are provided with shipping and storage guidelines.Dropping of the plates and vibrations during shipping can cause broken or cracked plates.Bd will continue to trend complaints for defects.This complaint can be confirmed for broken plates and contamination.A capa (corrective and preventative actions) 3076308 has been initiated to determine the root cause and corrective actions of the contamination.
