GeneQuence for Listeria provides for the detection of Listeria in food and environmental samples.
This DNA hybridization test employs Listeria spp.-specific DNA probes directly labeled with HRP, and a colorimetric endpoint to detect as little as 1 cfu of Listeria in a 25 g food sample when the specified enrichment protocols are used. A sample is considered negative for the presence of Listeria if the absorbance value (A450) obtained is less than 0.10. A sample is considered positive for the presence of Listeria if the absorbance value obtained is greater than or equal to 0.10. Positive samples should be confirmed by standard culture procedures, followed by biochemical identification.
- Sensitivity: 1–5 cfu/25 g
- Testing time: 2 hours (after 24 or 48 hour enrichment)
- Tests per kit: Up to 93
- Approvals: AOAC-RI 010403, HPB Canada MLFP-13
