In accordance with ISO 15213-1:2023, “ASR bacteria” is used if no confirmation step of characteristic colonies is carried out. If characteristic colonies are confirmed, the “Clostridium spp. sulfito-reducing agents” term is then applied.
- We draw your attention to the fact that we don’t contaminate our samples with collection strains but with strains isolated from dairy food matrices. Therefore, it is possible that some of them present unexpected phenotypic characteristics on some culture media.
enumeration of Listeria spp.♦, Listeria monocytogenes♦, enterobacteria♦ (at low rate) and detection of Salmonella♦
For Listeria and Salmonella: free choice methods. For Enterobacteria: a MPN method is recommended. For the enumeration on dishes, do not use ready-to-use rehydratable medium.
→ 5 samples containing between 0 and 10 000 Listeria/ml
→ 5 samples for the detection of Salmonella in 25 ml of milk
→ 5 samples containing between around 0 and 100 enterobacteria/ml
→ 1 vial of water to control the temperature of the samples at reception
- five 30 ml vials for the enumeration of Listeria spp. including Listeria monocytogenes and/or enumeration of Listeria monocytogenes
- five 60 ml vials for the detection of Salmonella
- five 30 ml vials for the enumeration of enterobacteria
All come in screw-capped vials with airtight seals
storage at 3 (±2) °C, with a bacteriostatic mixture preventing any bacterial growth in the milk, but rendered inactive upon dilution
CAUTION no bacterial growth occurs in the undiluted sample with ready-to-use rehydratable medium (because of the bacteriostatic mixture). Therefore do not use this type of medium for enterobacteria.
