DNA test enables precise tracking of Salmonella outbreaks

摘要

Researchers at the University of New South Wales have developed a type of DNA assay able to accurately identify and detect several serotypes of Salmonella, a common cause of food poisoning associated with eating raw or undercooked poultry and eggs.The new test is faster and simpler to use than current testing methods, which could help food safety experts and public health investigators better trace the origin of infections when outbreaks occur."It is important to monitor and reduce Salmonella contamination at the start of the food chain to reduce human infections and outbreaks," explained Ruiting Lan, PhD, of the School of Biotechnology and Biomolecular Sciences at the University of New SouthWales.
