Advances in molecular biology could transform the investigation of foodborne disease outbreaks, enabling faster and more accurate identification of the organisms responsible, according to the UK Food Standards Agency (FSA).
The Agency noted that DNA sequencing techniques, such as next generation sequencing, are one the most powerful laboratory tools to help tackle foodborne disease, such as E.coli and Salmonella.
With next generation sequencing, scientists can rapidly identify the complete DNA sequence of an organism. When used in combination with traditional epidemiological investigations, this can improve outbreak investigation and also provide clues to the likely origin of the strain involved.
FSA chief scientist Andrew Wadge said the Agency is fully committed to explore the potential of molecular biology tools, such as next generation sequencing, in the fight against foodborne disease.
"By using these techniques, outbreaks could be investigated more quickly and effectively than ever before. This could shape the way we respond to incidents in the future and, ultimately, save lives," Wadge added.
An estimated one million people a year in the UK suffer from foodborne illness, with 20,000 receiving hospital treatment and causing about 500 deaths. This costs the UK economy approximately £1.5bn every year, FSA said.
