Food safety is the set of practices to prevent harmful food contamination and foodborne illnesses.1
As a significant part of the global supply chain, food has extensive integration within a complex network of producers, distributors, and other entities before reaching consumers. Managing food safety is an essential part of the overall process to ensure public health.
Among the risks associated with food safety, foodborne illness related to microbial contamination from bacteria, viruses, and parasites represents a substantial threat to human health. Approximately 1 in 10 people worldwide become ill with contaminated food. In addition, food safety has a significant economic impact, resulting in $110 billion lost each year to productivity and healthcare costs from unsafe foods in low- and middle-income countries.2,3
Advanced sequencing technologies, such as next-generation sequencing (NGS), offer substantial improvements in food safety by providing sensitive detection coupled with high-throughput capabilities. Laboratory networks such as the GenomeTrakr Network use whole-genome sequencing to identify foodborne pathogens, including Salmonella, Listeria, E. coli, Campylobacter, Vibrio, Cronobacter, and more.4
Participating labs collect and share genomic and geographic data that can be accessed for comparison and analysis to assist in expediting public health responses.4 PulseNet is another such network that coordinates labs from all over the world using whole-genome sequencing to genomically identify foodborne illness outbreaks with known pathogens.5 These programs not only locate the source of foodborne illness but also alert the public and identify gaps in food safety systems.
