Listeria Testing - Lateral Flow System

DuPont™ Lateral Flow System for Listeria

Rapid antibody-based alternative to culture methods

LFS for Listeria testing

The DuPont™ Lateral Flow System (LFS) for Listeria uses test strips that employ a unique combination of anti-Listeria antibodies and colloidal gold conjugate coated on the surface of a membrane. After enrichment, drop the test strip into an aliquot of enriched sample broth, and read the results 10 minutes later. One control line is built into the lateral flow strip so you know the test has worked correctly. Two lines indicate a positive result.

Enrichment Media

LFS Listeria media provide a single-stage enrichment, with no transfers required. Simply mix the powdered media base with sterile water and add the supplement before use for results in 40 hours.

Applications

This LFS test detects Listeria on environmental surfaces and in a variety of ready-to-eat foods (such as deli meats, chicken nuggets, pepperoni, hot dogs, chicken salad and potato salad), dairy products (such as ice cream, soft cheese and milk), and fish products (such as cooked shrimp and smoked fish).  

Approvals

AOAC-RI Performance Tested Method #080501 - validated on a variety of foods including ready-to-eat, dairy, fish products and selected environmental samples, including rubber, painted concrete and stainless steel, to perform as well as the reference culture method, even at low spike levels (1-4 cfu/25g sample)  

Please note: LFS for Listeria is available outside the U.S. only.
