Research -High technology is the key to detecting foodborne outbreaks over space and time

Lex Blog

Most people think of foodborne illness outbreaks as spanning a few days or weeks. But, with current technology, disease detectives can find patients of a single outbreak spread across several years and multiple states.

That is the case with an ongoing outbreak of Listeria illnesses linked to fresh peaches that began in 2018. So far, 11 patients have been identified, most recently found in August this year. One of the patients died. Recent recalls of peaches, nectarines, and plums have been initiated while public health officials continue investigating the outbreak.

The links between people sickened in the outbreak this year and the initial patient in 2018 were made possible using whole genome sequencing (WGS). Whole genome sequencing has been likened to fingerprinting used in criminal investigations, but WGS allows the Centers for Disease Control and Prevention to look at millions of pieces of data.

“WGS examines more than 4.5 million ‘letters’ of the genetic code in disease-causing bacteria such as Salmonella. Bacteria closely related by WGS are more likely to have originated from the same source than more distantly related bacteria,” said John Besser, who retired in 2019 as Deputy Chief of the Enteric Diseases Laboratory Branch at the CDC. He continues to work on CDC-related projects through the Association of Public Health Laboratories.

“Ill persons in a WGS cluster will likely have shared exposure, such as a contaminated food product. By focusing on WGS clusters, investigators can detect outbreaks when they are small, even if cases are dispersed over multiple states or widely separated in time.”

Research – New sanitiser kills Salmonella in seconds

Adelaide Edu

Food poisoning outbreaks caused by bacteria such as salmonella could be significantly reduced if a new sanitiser is proven to be successful in the next stage of trials.

University of Adelaide researchers are developing plasma-activated water as an environmentally friendly food sanitiser that can kill foodborne superbugs in seconds.

“The results of our prototype trials are really exciting and showed that our sanitiser destroyed salmonella on chicken meat and eggs in just five seconds,” said lead researcher Dr Katharina Richter, a Future Making Fellow from the University of Adelaide’s Institute for Photonics and Advanced Sensing and Adelaide Medical School.

“We envisage that this sanitiser could be used as a spray or dip for at-risk foods such as eggs, meats, poultry and plant-based products during the manufacturing process, potentially providing a chemical-free alternative to current sanitisers and preventing disease.”

More than four million cases of foodborne disease are estimated to occur in Australia each year. Symptoms can range from mild to severe and include diarrhoea, vomiting, fever, aches, and pains.

“Vulnerable people such as young children, the elderly, pregnant women and people with weakened immune systems are most at risk of severe consequences and could even die of foodborne illnesses,” said Dr Richter.
