Minimize Food Recalls by Tracking Contaminations

DNA PathoTracker: Investigate Sources of Contamination Through Whole Genome Sequencing of Pathogens

How secure is your global supply chain? How stringent are your quality checks?

Food recalls due to pathogen contaminations and outbreaks of foodborne diseases are among the most dreaded incidents in the industry. Whole Genome Sequencing (WGS) has been globally accepted as the most accurate, high resolution method to identify pathogens. Given the greater strain discrimination compared to more traditional methods, WGS is capable of helping you identify sources of contamination and decide which sanitary or preventative checks need to be improved. Combining the genomic information with data such as the date and place of findings can help track down contaminations prior to any affected food products reaching your end consumers.

Why DNA PathoTracker?

By integrating DNA PathoTracker into your QC, you are going to

Gain improved clarity and overview on your contamination events through increased analytical resolution.

Respond much faster in the event of a contamination due to source identification at an early stage.

Identify pathogens based on DNA which is unique for each bacterial strain and is highly stable against environmental influences.

Make critical improvements in your HACCP system by finding out which preventive / QC measures may have failed.

Build a customized pathogen database helping you to compare against thousands of strains and samples globally at the same time.

Minimize costly recalls by utilizing a highly scalable solution that is able to help you throughout your entire supply chain.

Frequently Asked Questions

What is Whole Genome Sequencing?  Whole Genome Sequencing (WGS) delivers exact DNA sequence data for the entire genome of an organism. It is based on next-generation sequencing (NGS), also known as high-throughput sequencing, which is a massively parallel DNA sequencing technology that allows for the analysis of samples and systems at a level that was never possible before. NGS machines can sequence large samples more cost-effectively than traditional methods, and in the process also generate more detailed genomic information.

Can WGS be used for production strain profiling? WGS cannot only be used in the case of microbial contamination issues. It can also be a useful tool for a full characterization of valuable production strains. The knowledge of the whole genome sequence leads to a unique definition of the production strain. This can be very helpful in case of e.g. patent infringement issues.

What about microflora? Complex bacterial / fungal mixed populations can also be analyzed by WGS. Our “Microbiota Screening Services” enable an insight into the microflora of food / environmental samples as well as fermentation processes by the use of so-called barcoding regions in the microbial DNA, thus identifying the genus or species. Our “Metagenomics Service” looks at the total DNA of a complex sample containing mixed populations and allows for an identification of strains and subspecies. Both approaches include and identify even non-cultivatable microorganisms.
