COMPASS® Bacillus Cereus Agar: Reliable Detection and Counting of Bacillus Cereus

COMPASS® Bacillus Cereus Agar is a solid medium designed for the detection and enumeration of spores and vegetative forms of Bacillus cereus in products intended for human and animal consumption. This medium allows direct detection and enumeration without additional purification steps or biochemical confirmation.

Key Advantages:

1. Reliable: Validated by AFNOR Certification according to NF EN ISO 16140.
2. Performance: Excellent recovery of vegetative and spore form, with specific detection of Bacillus cereus.
3. Easy: Characteristic green colonies and inhibition of secondary flora.
4. Fast and Economic: Detection and counting within 24 hours on 1 plate without fixing.

Detection technology:

1. Prepare a 10% dilution of the food sample in Peptone water.
2. Homogenise the sample for 1 minute.
3. Apply dilutions to the surface of COMPASS® Bacillus cereus Agar plates.
4. Incubate the plates at 37°C for 24 hours.
5. Examine for typical Bacillus cereus colonies and confirm identification.
6. Report the results as the number of colonies per gram of food sample.
