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 1099123 was satisfactory 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.A sample of plates are incubated at 25 degrees c and at 35 degrees c for approximately 72 hours.All physical attribute and bioburden testing performed on this batch was satisfactory per bd internal procedures.Affected product does not have any sterility claims; the product is tested for bioburden prior to release to ensure that it conforms to product specifications.However, this does not ensure that the end-user will not receive a contaminated plate.The complaint history was reviewed, and other complaints have been taken on batch 1099123 from other customers.Retention samples from batch 1099123 were not available for inspection.Two photos were received for investigation.One photo shows two stacks of bi-plates in a plastic bag.Some microbial growth is visible on at least two plates in the bag.The other photo shows a sleeve from batch 1099123 and a stack of bi-plates.There are at least three plates with microbial growth visible in the photo.No return samples were received for investigation.This complaint can be confirmed for contamination in batches 1099123 and 1106174 by the photos provided.However, media splash over has been confirmed in batches 1099123 and 1106174 from photos in other complaints taken on these batches.Due to the number of complaints taken for contamination for material 222239, a capa (corrective and preventative actions) has been initiated to determine the root cause and corrective actions of the contamination.Bd will continue to trend complaints for these defects.
