The number of reported incidents and recalls related to Listeria and L. monocytogenes has been increasing, and processors are making efforts to rid their facilities of harborage organisms and sites.
The way processors view their responsibilities regarding microbiological testing is changing. Regulatory pressure and a focus on food safety are causing changes in where processors do their testing.
Whether you are just setting up your environmental Listeria monitoring program or reassessing your existing program, there are basic elements that you will want to include.
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.
The Listeria Right Now™ test system detectsListeria, 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.
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.
Advancements in testing automation have allowed for the development of smaller, more flexible solutions that fit into existing laboratory configurations and workflows. BioControl System’s Assurance GDS® system utilizes the targeted isolation capabilities of immunomagnetic separation and the specificity of DNA-based detection to provide fast and accurate results for even the most challenging food samples.
