H6 investigation summary: during manufacturing of material 221267, 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 reviews for batches 2196578, 2196579, and 2206453 were satisfactory and no quality notifications were generated during manufacture or 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 histories were reviewed and no other complaints have been taken on batches 2196578, 2196579, and 2206453 for contamination, uneven fill, or warped dishes.No retention samples from batches 2196578, 2196579, and 2206453 were available for inspection.There were seven pictures received for investigation.The first picture shows a plate with contamination on the agar surface (batch number and time stamp not visible).The second photo shows a plate from batch 2206453 (time stamp 1550) with split agar.The third photo shows a plate from batch 2206453 (time stamp 1550) with a melted or warped plate.Photos four through seven contain screenshots from a plate reader showing growth on chocolate agar compared to other agar plates.Due to the chocolate agar plates present in these photos being used, it can not be concluded that the growth present on these plates is due to the media (batch numbers and time stamps not visible.No returns were received for investigation of this complaint.This complaint can be confirmed for split agar and warped dish in batch 2206453.This complaint can not be confirmed for contamination in batches 2196578 or 2196579 with the photos received for investigation and lack of batch number verification.No complaint trends for these defects have been identified; no actions are indicated at this time.Bd will continue to trend complaints for defects.See h.10.
