Microbiologics recalls KWIK-STIK Rhizopus stolonifer control kits due to contamination with Aspergillus brasiliensis. Users may see A. brasiliensis growth. No remedy specified in recall notice.
The positive control material (Rhizopus stolonifer) within the KWIK-STIK assembly was contaminated with another fungal organism (Aspergillus brasiliensis). As a result, users may observe A. brasiliensis growth when using the control material.
Microbiologics is recalling specific KWIK-STIK quality control kits because the fungal control material was contaminated with another fungus. This could cause users to mistakenly identify a different fungus when testing culture media.
The control material in the KWIK-STIK kit was contaminated with Aspergillus brasiliensis instead of Rhizopus stolonifer. When users run the control test, they might see growth of A. brasiliensis instead of the expected Rhizopus stolonifer, leading to incorrect results.
Users of the KWIK-STIK Rhizopus stolonifer control kits (REF 0209P and REF 0209K) who test culture media. Lab technicians and microbiology researchers are most at risk.
Check for the product name 'KWIK-STIK Rhizopus stolonifer (+) derived from ATCC 6227b'. The kits have model numbers REF 0209P (lot numbers 209-37-1 to 209-37-5) or REF 0209K (lot number 209-37-2).
Identify if your KWIK-STIK kit has model REF 0209P with lot numbers 209-37-1 to 209-37-5 or REF 0209K with lot number 209-37-2.
The control material in the KWIK-STIK kit was contaminated with Aspergillus brasiliensis instead of Rhizopus stolonifer, which could cause incorrect test results.
The recall notice does not specify a remedy, so no action is required beyond checking if your kit matches the described model and lot numbers.
The recall notice does not mention any safety hazard that could cause injury, only incorrect test results.
