Food safety testing volumes are increasing and focus on Listeria.
Whole-genome sequencing is a common tool for outbreak detection and investigation.
No trend has been reported as being more impactful than the increase in the amount of analytical testing being conducted—especially the increase in testing for microorganisms.
A new approach for significantly improving detection probabilities and reducing the need for manual verification of foreign material contamination of food products is described.
Shiga toxin-producing Escherichia coli strains can cause foodborne illness, necessitating the expansion of testing for these organisms.
The ability to rapidly detect the presence of viable pathogens along the production chain is essential for determining intervention and control strategies.
Transgenic methods have been used for over 25 years to incorporate well-characterized genes from a foreign (different plant or nonplant species) donor into a plant host that endows it with some desirable trait.
As a result of the changing regulatory landscape, there is need for more accurate identification and quantification of contaminants in environmental and food-related samples.
Most physical contaminants of foods, such as pieces of hard plastic or wood, can cause consumers immediate injury; this includes all types of foods, including beverages, bottled water, and nutritional and functional products.
This new sensing mechanism can detect very faint traces of foodborne viruses that can help prevent epidemics and further transmission.
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.
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.
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.
With so many ingredient, flavor and preservative combinations possible, food matrices can be very complex. Bia Diagnostics can develop a customized plan to meet your specific testing needs, including evaluation and validation of the method with each specific matrix that the assay would encounter in your facility.
The Biosart® 100 Monitor system, a Sartorius Biotech product that is distributed by Weber Scientific, has been designed specifically for the detection and enumeration of microorganisms potentially present in food, beverages and water. It is a membrane filtration system that is the microbiological method of choice for many customers testing fluid product, particularly for brewing, juice, soft drink and potable water laboratories.
Survey results are presented from more than 100 food processors on their preparations for compliance with the Food Safety Modernization Act.
New devices, so-called electronic noses, have been described as both a cost-effective and a timesaving substitute for the determination of shelf life, food quality and origin.
Science continues to seek new solutions to combat an unfortunately all too common problem.
