New NordVal International certificates
NordVal International Certificate 050 issued to HyServe for Compact Dry YM RAPID has been renewed. Compact Dry are ready-to-use dry media sheets comprising culture medium and a cold-soluble gelling agent. The Compact Dry YM RAPID method contains chromogenic medium and selective agents for the detection and enumeration of yeasts and moulds after 3 days of incubation. The method is applicable for a broad range of foods with an aw of >0.95. Like the reference method, it is not intended for mould spores or for heat resistant mould species. See the certificate here.
NordVal International Certificate 049 issued to Bio-Rad for RAPID’Staph has been renewed. RAPID’Staph is based on an optimised Baird-Parker formula for enumeration of S. aureus. Some Staphylococcus coagulase positive strains can give colonies with a small or no halo after 24 hours of incubation. Additional incubation of 24 hours could be necessary to see the halo. Using RAPID’Staph the typical staphylococci produce gray to black colonies that are shiny and cover with a clear halo. The method is applicable for enumeration of coagulase-positive Staphylococcus (Staphylococcus aureus and other species) in a broad range of foods. See the certificate here.
NordVal International Certificate 022 issued to BioRad for "RAPID´L.mono" has been renewed. The principle of the RAPID’L.mono medium is a chromogenic detection of the Listeria monocytogenes grown on medium containing a selective mixture. RAPID‘L.mono detects Listeria monocytogenes in 24 hours and other Listeria species in 24 and 48 hours. The method is applicable for the enumeration of Listeria monocytogenes and for the detection of other Listeria species in a broad range of food and environmental samples. See the certificate here.
NordVal International Certificate 030 issued to Qualicon for "BAX® System PCR Assay for Salmonella" has been renewed. The Bax® System for detection of Salmonella is targeting a specific bacterial DNA fragment, which is specific for Salmonella and not present in any other bacteria, and hence is an indicator of the presence of Salmonella. The method is applicable for the detection of Salmonella spp. in a broad range of foods, animal feed and environmental samples. See the certificate here.
