Validation of 3M's Salmonella Molecular Test
Extends to Animal Feed, pet Food and primary
production Samples
3M Food Safety has announced that the 3M™ Molecular
Detection Assay 2 - Salmonella has earned matrix extensions
from AFNOR Certification for its NF validation.
In February 2017, the test was first certified by AFNOR
(Certificate reference number: 3M 01/16-11/16) for detection
of Salmonella spp. in all human foods as well as in samples from
the food processing environment, excluding primary production
samples. The pathogen test's validation now encompasses
samples taken from primary production as well as from animal
feed and pet food.
The Salmonella pathogen test kit is part of the 3M™ Molecular
Detection System platform, award-winning technology that
combines isothermal DNA amplification and bioluminescence
detection to produce rapid, accurate results with fewer steps,
reducing costs and technician time. Enhanced with a proprietary
3M nanotechnology, the test gives processors a streamlined
workflow that enables same-day or next-day pathogen test
results and faster, more confident food safety decisions.
Comparative research shows that the 3M Molecular Detection
Assay 2 - Salmonella will process a batch of 96 samples 1.7 times

faster than the closest competitive technology. Last year, the 3M
Molecular Detection System became a primary method of the
USDA Food Safety and Inspection Service for the detection of
both Salmonella and Listeria.
"We are committed to providing a wide range of customers
with pathogen tests that have been rigorously and relevantly
validated," said Lisa Monteroso, 3M Food Safety regulatory
affairs specialist. "Salmonella is an organism that can persist in a
variety of foods - including those that are low moisture - so we
are pleased to share additional scientific support for our assay's
performance and use in these important categories."
The NF validation certification process begins with a
scientific comparison of testing methods; a single, expert lab
thoroughly tests the technology's effectiveness versus the NF
EN ISO 6579 reference method. Subsequent to that, multiple
laboratories coordinate to compare the efficacy of both the
new test method and reference method under reproducible and
repeatable conditions.

Delicate and Quiet Operation with Alfa Laval's
New Robust Twin Screw pump
Designed for handling fluids which are sensitive, abrasive, and
either high or low viscosity, the Alfa Laval Twin Screw Pump
is ideal for use in hygienic applications in the dairy, food and
beverage, and personal care industries.
"The Twin Screw Pump is the ideal choice for both high
and low viscosity liquids, all pumped perfectly with complete
reliability," says John Walker, pump portfolio manager.
Additional benefits of the Alfa Laval Twin Screw Pump are
that it is quiet and virtually pulse-free, as well as being smooth
and gentle during operation. These characteristics make the
pump an excellent choice for handling sensitive products.
Built on a robust, reliable platform that meets stringent
hygienic standards, the pump is capable of handling both
product transfer and Cleaning-in-Place (CIP). Its low pulsation
characteristics and excellent solids handling capabilities reduce
the risk of product damage, thereby improving product quality.
Maintenance is simplified and process uptime increased.
Two-in-one operation provides easy handling of process
media of varying viscosities as well as CIP fluids. This simplifies
piping and pump control, cutting costs and minimizing
contamination risks. Superior suction performance with
excellent lift capability and low NPSHR provides installation
flexibility and increases product recovery.

Quick, easy seal replacement with the pump in place is
made possible, thanks to a cartridge seal with a truly frontloading, self-setting design. This maximizes process uptime
and minimizes maintenance costs. An optional seal service kit
program adds maintenance flexibility and cuts operating costs.
The Alfa Laval Twin Screw Pump features a clean, external
stainless steel finish with profiled elastomers and mechanical
seals fully surrounded by the product. Designed for maximum
cleanability using FDA-conforming materials, the pump is both
EHEDG and 3-A certified. An optional ATEX version enables
use in hazardous zones.
