Salmonella Testing - Lateral Flow System

DuPont™ Lateral Flow System for Salmonella AD

Rapid antibody-based alternative to culture methods

LFS for Salmonella testing

The DuPont™ Lateral Flow System (LFS) for Salmonella AD uses test strips that employ a combination of optimized anti-Salmonella 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

Salmonella AD enrichment media include a proprietary base with selective supplement and a secondary media, optimized for use with the Salmonella AD test strips. The phage-based media improve sensitivity and specificity by reducing background flora and promoting the growth of Salmonella.  Enrichments are complete in as little as 22 hours for liquid eggs and processed foods and 32 hours for raw meats and carcass rinses.

Applications

The DuPont™ LFS for Salmonella AD has been tested on a variety of foods, including raw meat and poultry, processed meat, fruits, vegetables, dairy products, nuts, animal feed, and carcass rinses.

Approvals

AOAC-RI Performance Tested Method #021001 - validated on raw ground beef, raw ground chicken, liquid eggs, sliced cooked turkey and chicken carcass rinses to perform as well as the reference culture method, even at low spike levels (1-4 cfu/25g sample) Validation studies also support 98% inclusivity and 100% exclusivity.

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