TL;DR: These data represent the first report fully integrating WGS analysis with geographic mapping and a novel use of transmission networks, and showed that WGS vastly improves the ability to delimit the scope and source of bacterial food-borne contamination events.
Genomics of foodborne pathogens for microbial food safety.
Marc W. Allard,Rebecca L. Bell,Christina M. Ferreira,Narjol Gonzalez-Escalona,Maria Hoffmann,Tim Muruvanda,Andrea Ottesen,Padmini Ramachandran,Elizabeth Reed,Shashi Sharma,Eric L. Stevens,Ruth Timme,Jie Zheng,Eric W. Brown +13 more
TL;DR: Whole genome sequencing has been broadly used to provide detailed characterization of foodborne pathogens to develop new applications in food safety using WGS approaches such as outbreak detection and characterization, source tracking, determining the root cause of a contamination event, profiling of virulence and pathogenicity attributes.

Listeria monocytogenes in Stone Fruits Linked to a Multistate Outbreak: Enumeration of Cells and Whole-Genome Sequencing
Yi Chen,Laurel S. Burall,Yan Luo,Ruth Timme,David Melka,Tim Muruvanda,Justin Payne,Charles Wang,George Kastanis,Anna Maounounen-Laasri,Antonio J. De Jesus,Phillip Curry,Robert Stones,Okumu K'Aluoch,Eileen Liu,Monique Salter,Thomas S. Hammack,Peter Evans,Mickey E. Parish,Marc W. Allard,Atin R. Datta,Errol Strain,Eric W. Brown +22 more
TL;DR: The diversity among the outbreak-associated isolates and the inclusion of PFGE-matched, but epidemiologically unrelated, isolates demonstrate the high resolution of WGS.

Precision long-read metagenomics sequencing for food safety by detection and assembly of Shiga toxin-producing Escherichia coli in irrigation water.
Meghan Maguire,Julie A. Kase,Dwayne Roberson,Tim Muruvanda,Eric W. Brown,Marc W. Allard,Steven M. Musser,Narjol Gonzalez-Escalona +7 more
TL;DR: In this paper, the limits of detection and classification of Shiga toxin-producing Escherichia coli (STEC) by qPCR and nanopore sequencing using 24 hour enriched irrigation water artificially contaminated with E. coli O157:H7 (EDL 933) were determined.
Genome-wide methylation patterns in Salmonella enterica Subsp. enterica Serovars.
Cary Pirone-Davies,Maria Hoffmann,Richard J. Roberts,Tim Muruvanda,Ruth Timme,Errol Strain,Yan Luo,Justin Payne,Khai Luong,Yi Song,Yu-Chih Tsai,Matthew Boitano,Tyson A. Clark,Jonas Korlach,Peter Evans,Marc W. Allard +15 more
TL;DR: Using single molecule real-time (SMRT) DNA-sequencing, the complete genomes of eleven Salmonella enterica isolates from nine different serovars were sequenced and the whole-genome methylation patterns of each genome were analysed.
