World-leading microbiology brand Oxoid
has launched the AFNOR-validated Salmonella Precis
rapid culture method. This method provides results in just two days – up to
three days faster than standard Salmonella culture methods used in food
testing laboratories.
Recently validated and approved by AFNOR to ISO 16140 standard,
the Salmonella Precis method can be used with food,
animal feed and environmental samples. The procedure is carried out in three
simple steps – enrichment, plating and confirmation – and requires no specialised equipment.
The single 18-hour enrichment is achieved using Oxoid
ONE Broth-Salmonella, a highly nutritious medium that promotes recovery and
growth of the target organism while inhibiting competing organisms. The
growth promoter in the medium allows the recovery of stressed Salmonella
cells, even when present in very low numbers.
Plating is undertaken on Oxoid Brilliance
Salmonella Agar, the first in a new class of chromogenic
media that incorporates Inhibigen technology. The Inhibigen selective agent improves the recovery of
Salmonella by reducing background flora. Chromogens
in the medium aid easy identification and differentiation by producing
brightly coloured colonies.
Cheryl Mooney, product manager at Oxoid, said:
“This simple method is validated by AFNOR to ISO 16140 standard and offers
significant time savings compared to standard culture methods. The Oxoid Salmonella Precis method
is, therefore, extremely valuable to food testing laboratories where a quick
result is required. In addition, the fact that technicians only have to use a
single broth and plate for each sample minimizes handling,
saves on lab space and reduces the volume of waste.”
