Frequently Asked Questions

What are the key advantages of VIA methodology?
VIA provides enhanced analytical confidence through integrated positive and negative control mechanisms, easily interpretable results, accelerated product release timelines, simplified single-stage pre-enrichment, and completely ready-to-use reagent formulations.
How does TECRA VIA compare to conventional culture methods?
Conventional isolation of E.coli O157 is challenging due to competitive inhibition from other E.coli serotypes in enrichment cultures, particularly at elevated background levels. TECRA VIA provides direct screening capability and superior sensitivity while requiring only single-stage inoculation versus multi-stage subculture procedures in classical methods.
Why is TECRA VIA superior for heat-treated samples?
TECRA Visual Immunoassay demonstrates greater reliability compared to traditional methods when analyzing heat-exposed samples, where the target organism may be partially compromised.
What sample types can be analyzed?
The system is validated for food, water, environmental samples, raw food products, cosmetics, and pharmaceutical matrices including beef samples (validated on 375g matrices).
Does TECRA VIA detect non-motile strains?
Yes, TECRA methodology can detect E.coli O157:H7 serotypes that do not express the H7 antigen in culture, expanding detection capability beyond culture-based approaches.
What regulatory compliance does this system provide?
TECRA VIA methodology is fully compliant with USDA FSIS E.coli O157:H7 test directives.
