StrainTrace delivers rapid Listeria strain tracking that tells food producers not just whether a strain is present — but where it came from and whether it's been there before.
Listeria monocytogenes can survive refrigeration and persist in plant environments for years. Knowing a strain is present is only the beginning — food producers need to know its origin, its history, and whether it's been seen before.
Standard environmental monitoring can't tell you whether a detected strain is a persistent resident or a one-time introduction from incoming materials or personnel.
Genome sequencing can generate data that links a facility's strain to a past or future outbreak — a significant liability that has made the food industry resistant to adopting it.
PFGE takes 2–3 days and requires specialized equipment. Other older platforms have been discontinued. No modern, accessible commercial solution exists for routine strain typing.
Sequencing-based platforms require large capital investments and are only cost-effective at high volumes. Small and mid-size labs have been priced out of strain tracking entirely.
A targeted molecular assay that generates a unique strain fingerprint from a set of genetic markers — delivering actionable results in hours, with no capital investment and no sequencing risk.
AmpliTyping uses single-use consumables compatible with equipment most food safety labs already have in place — eliminating upfront cost as a barrier to adoption.
Unlike batch-dependent platforms, AmpliTyping can run a single presumptive positive immediately. No waiting days for a full batch to accumulate.
Strain fingerprints are generated without producing genome sequence data. Client-specific databases are private, with no connection to regulatory body databases.
Pattern databases track recurrence of strains by date and location, helping producers identify persistent harborage sites and distinguish resident from transient strains.
AmpliTyping is designed to be accessible to third-party labs of all sizes — with per-test pricing comparable to what the market has historically accepted for strain typing.
From presumptive positive to strain pattern — same day.
Swab or sponge sample taken from facility surfaces as part of routine environmental monitoring.
Standard pathogen screening flags a Listeria positive. The same sample lysate is used directly — no further processing required.
A targeted set of genetic markers is analyzed. Presence or absence of each target generates a unique binary fingerprint for the strain.
The fingerprint is compared against the facility's private history. New strains are logged; recurring strains are flagged with location and date data.
Results enable rapid response — confirming a persistent harborage site or clearing a transient introduction.
StrainTrace was founded by scientists with deep, hands-on experience in diagnostic microbiology and molecular pathogen detection for the food industry. Our team has led R&D, validation, and commercialization of the assay platforms that food safety labs rely on every day.
We recognized a critical gap left by the discontinuation of the only commercial Listeria strain tracking platform on the market — and set out to build a better, more accessible solution. AmpliTyping is designed from the ground up to fit into existing lab workflows, reduce barriers to adoption, and give food producers the longitudinal strain data they need to make faster, more confident decisions.
Whether you're a testing lab, a food manufacturer, or a potential partner, we'd love to connect and tell you more about AmpliTyping.
