Real-Time PCR for Cutting-Edge Food Testing
Real-Time PCR for Cutting-Edge Food Testing

As molecular methods for pathogen detection continue to improve, emerging pathogens are being described around the world in molecular terms. The use of real-time PCR methods developed by Bio-Rad has the benefits of automation, high sensitivity, high precision and accuracy, and the flexibility to assay for more than one pathogen simultaneously.

Listeria Testing Results in under 60 Minutes
<i>Listeria</i> Testing Results  in under 60 Minutes

The Listeria Right Now™ test system detects Listeria, including the pathogenic Listeria monocytogenes, in environmental samples in under 60 minutes—with molecular-level accuracy and without the need to enrich samples. The test has also been submitted for AOAC Performance Tested certification to further validate its accuracy.

Whole-Genome Sequencing May Be Hot, But Which Rapid Micro Method Won’t Leave You Burned?
Whole-Genome Sequencing May Be Hot, But Which Rapid Micro Method Won’t Leave You Burned?

Can you tell whether whole-genome sequencing (WGS) or DNA fingerprinting is better for ensuring food safety? In truth, both are equally powerful techniques. Both have advantages and disadvantages and are realistic choices for maintaining food safety.
