Researchers have evaluated a handheld DNA sequencing device for use in environmental monitoring at food factories.

The study, by researchers from the Teagasc food research program and APC Microbiome Ireland’s Science Foundation Ireland Research Centre, tested portable DNA sequencers as a routine microbial monitoring tool in food production facilities. It

Researchers say they believe they have found a cheap method to identify bacteria in a few hours on a mobile-phone-sized device.

The bacterial identification method, called ON-rep-seq, examines strain-specific fragments of the bacterial genome, allowing results that earlier required DNA sequencing of the whole bacterial genome. The method also returns

Scientists are urging government officials to consider helping to develop an international database to share and analyze DNA sequences.

Such a system is a platform for storing whole genome sequencing (WGS) data on the full genomes of investigated microorganisms such as bacteria, viruses and parasites, providing quick characterization and treatment

University of Georgia food scientist Xiangyu Deng has created a system that can identify subtypes of foodborne pathogens in a fraction of the time taken by traditional methods.

Quick detection and pathogen fingerprinting can save lives by helping to identify foodborne illness outbreaks and their victims, thereby making it easier
