The »ready-to-use« Compact Dry X-BC plate from HyServe combines the properties of chromogenic dry media and gel contact plates. It is used for the quantitative detection of Bacillus cereus in food samples. The bacterium Bacillus cereus produces grampositive spores and is commonly found in soil and water. Therefore, it enters the food processing chain relatively easily. Bacillus cereus can contaminate foods; furthermore, its emetic and diarrhoeagenic enterotoxins cause vomiting and diarrhoea after consumption. Routine testing procedures for Bacillus cereus are thus recommended. A simple and certified method for this is: Compact Dry X-BC. After applying the sample (1 ml), the dehydrated Compact Dry X-BC plate becomes gel-like. The sample self diffuses evenly. Further steps, for example manual spreading, are not required.
Compact Dry X-BC has been validated to ISO 16140 against the reference method (EN ISO 7932:2004) for the detection of Bacillus cereus. Compact Dry X-BC is also MicroVal (No. 2011-LR41) and NordVal (No. 045) approved. The ready-to-use plate can therefore be routinely applied by certified users.
