Every year, the presence of Listeria monocytogenes in food remains one of the leading causes of product recalls in France and Europe. Behind every recall is a production site that must react quickly, a product pulled from shelves, and constant vigilance to protect consumers. This is precisely the challenge that Loop Dee Science, a biotech company based near Caen, helps address every day.
International recognition for a method designed for the field
Loop Dee Science announces it has earned AOAC Performance Tested Methods℠ 082603 certification, issued by the AOAC Research Institute, for its LoopDeetect Listeria monocytogenes detection kit. This recognition validates the reliability of a method capable of delivering a result in under 90 minutes, directly in the field, with no enrichment step and no lab expertise required.
“This certification rewards years of work by our teams on a technology designed for the field. It is an immense source of pride to see a method conceived and developed here, in Normandy, validated against one of the most demanding standards in the world.”
Louis-Marie Rocque, President of Loop Dee Science
What this means in practice for quality teams
In a food processing plant, a Listeria monocytogenes check is never trivial: the wait for a result can halt a production line, delay a shipment, or strain stock management. By bringing this turnaround down to under 90 minutes, LoopDeetect lets quality and hygiene managers decide sooner, using a method that on-site teams can operate directly.
This speed and reliability also fit into a broader picture: during an IFS (or BRC) audit, a site’s ability to demonstrate rigorous, well-documented control of its pathogen checks is a key point of scrutiny. Having a fast, reliable method validated by an internationally recognized standard such as AOAC PTM provides concrete support for meeting these requirements, beyond simple regulatory compliance.
An innovation that protects
To the general public, AOAC PTM certification may not mean much. Yet it’s precisely this kind of invisible but rigorous control that helps ensure a product is pulled from shelves before it reaches a consumer, rather than after. Faster, more reliable methods mean decisions made earlier in the production chain, less prolonged doubt over a batch, and ultimately, better protection for everyone.
Expertise developed in Normandy
This certification builds on Loop Dee Science’s in-house expertise in molecular biology and microbiology, developed within its own equipped laboratories and cleanrooms. It reflects the work of a team whose solution design remains constantly guided by real-world field needs.
Building on this recognition, Loop Dee Science aims to accelerate its commercial growth among French and European manufacturers, and is now opening its capital to new investors to support this growth.
