GenomeTrakr Network

The GenomeTrakr network is the first distributed network of laboratories to utilize whole genome sequencing for pathogen identification. It consists of public health and university laboratories that collect and share genomic and geographic data from foodborne pathogens. The data, which are housed in public databases at the National Center for Biotechnology Information (NCBI), can be accessed by researchers and public health officials for real time comparison and analysis that promises to speed foodborne illness outbreak investigations and reduce foodborne illnesses and deaths.

Real Time Food Safety Applications of the GenomeTrakr Network

FDA/CDC Real Time Listeria Project

Further integrating the marriage of clinical, food, and environmental pathogen analysis, FDA has partnered with CDC in an effort to sequence every clinical, food, and environmental isolate of Listeria monocytogenes collected in the U.S.  CDC is primarily sequencing clinical samples while FDA and the state laboratories are sequencing food and environmental samples.  The genomic sequences and corresponding collection information for the samples are publicly available via the NCBI website.

Minn./Wash./NY/FDA Real Time Salmonella Enteritidis Project

State labs in Minnesota, Washington, and New York have paired with FDA to conduct real time sampling of Salmonella Enteritidis isolates from clinical, food, and environmental samples.  The genomic sequences and corresponding collection information for the samples are publicly available in the GenomeTrakr database maintained by NCBI.

Additional Foodborne Pathogen Sequencing

GenomeTrakr member labs initially focused their whole genome sequencing efforts primarily on Salmonella and Listeria pathogen isolates.  However, performing whole genome sequencing on other foodborne pathogens will further leverage the public health benefits that can be derived from the open sharing of the genomic information.  To this end FDA and its partners are also sequencing E. coli, Campylobacter, Vibrio, Cronobacter, etc. isolates, as well as parasites and viruses.  Many public health laboratories have pathogen isolates from past outbreaks stored in their freezers.  These isolates hold a treasure trove of genomic information waiting to be unlocked by whole genome sequencing. FDA encourages those labs to sequence those isolates and upload the genomic information to the GenomeTrakr database at NCBI.

Collaborations with Independent Academic Researchers:
In addition to state labs, university labs, federal labs, and labs located outside of the U.S., the GenomeTrakr network has collaborative relationships with a number of independent researchers, including graduate students, who supply foodborne pathogen isolates and/or perform whole genome sequencing on the isolates.

Data Curation:
Data curation and bioinformatic analyses and support are provided by the National Center for Biotechnology Information (NCBI) in Bethesda, MD.
