Lateral Flow System

The Hygiena™ Lateral Flow System is a simple and inexpensive alternative to traditional culture methods for routinely screening foods for pathogens. This system offers optimized media, requires no capital investment and only minimal training. Low labor and material costs also help make this system a cost-effective screening tool.

 

Clear , Rapid Results 

Using a unique combination of antibodies and highly engineered colloidal gold conjugate coated on the surface of a membrane, the Hygiena Lateral Flow System yields clear, reliable results—which are available much faster than conventional, culture-based testing. After a few simple steps of preparation, the sample wicks up the test strip by capillary action. Within 10 minutes, if the target pathogen is present in the sample, two red lines are formed. If not, only the control line— which lets you know that the test has worked correctly—appears. The test can detect 1 colony forming unit (cfu) in 25 grams of sample.

 

Optimized Media

The Hygiena Lateral Flow System uses specifically designed media that facilitate the maximum recovery of both sub-lethally injured and healthy cells, while inhibiting closely related competitive flora. Using this optimized media simplifies and shortens enrichment times.

 

Full Product Line

Tests and media are available for Salmonella, Listeria and E. coli O157 (including O157:H7). Test strips have a long shelf and can be stored at room temperature, saving valuable refrigerated storage space in your laboratory. These Hygiena Lateral Flow Systems have been certified by the AOAC Research Institute as Performance Tested MethodsSM.

Performance

UltraSnap’s superior performance was validated in a third party study conducted by a large reference laboratory. In addition to superior repeatability (Diagram 1), Hygiena’s system demonstrated outstanding performance for linearity, sensitivity, and accuracy.

Hygiena™ Lateral Flow System for Salmonella AD
Tests are designed to detect Salmonella in raw ground beef and chicken, liquid eggs, sliced cooked turkey, carcass rinses and peanut butter. This second generation product uses optimized antibodies on the test strips and phage based enrichment media for improved sensitivity and specificity.
This method uses a simple two-stage enrichment and requires no sample boiling. The same protocol can be used for all food types, and the assay takes only 10 minutes –even for high– burden samples.
Hygiena™ Lateral Flow System for Listeria
Tests are designed to detect Listeria on environmental surfaces and in a variety of
ready-to-eat foods, dairy products and fish products. The specially designed Hygiena
Lateral Flow System media for Listeria reduces enrichment to a single stage and 40
hours. After a short boiling step, results are available in 10 minutes.
Hygiena™ Lateral Flow System for E. coli O157
Tests are designed to detect E. coli O157, including O157:H7, in raw beef (bonelessand ground) and processed foods, including fruit juices. When used with Hygiena Lateral Flow System media for E. coli O157, enrichment is complete in as few as 8 hours and up to 18 hours. Alternatively, you can use standard media for 20-hour  enrichment. Sample boiling is optional and will not affect results, which are available in 10 minutes.
