NewsTrace levels of food pathogen do not always translate to health risk, says study
Ultra-sensitive food safety tests may drive food waste and unavailability with limited public health benefit, according to a study. These food safety measures and ultra-sensitive tests may drive edible food being thrown away, excessive packaging, and extra costs for consumers.

NewsNew study fills research gap in food safety to better protect pregnant women from Listeria
Researchers developed new biologically plausible dose-response models — one for maternal infection and one for stillbirth — built on data from guinea pigs and gerbils, which share key biological traits with humans relevant to listeria pathogenesis.

News‘Bugs delivering drugs’ – new approach to colorectal cancer treatment using common food-borne bacteria
Researchers have published a novel approach to fight colorectal cancer, using modified bacteria as a courier to deliver potent cancer-killing proteins into tumor cells.

NewsBasic research on Listeria bacteria leads to unique cancer therapy
After nearly 40 years of research on how Listeria bacteria manipulate our cells and battle our immune system to cause listeriosis, researchers have discovered a way to turn the bacteria into a potent booster of the immune system — and a potential weapon against cancer.

NewsNew AI model improves accuracy of food contamination detection
Researchers have significantly enhanced an artificial intelligence tool used to rapidly detect bacterial contamination in food by eliminating misclassifications of food debris that looks like bacteria. Current methods often require specialized expertise and are time consuming — taking several days to a week.

NewsNew research finds crosstalk inside cells helps pathogens evade drugs
Biologists have uncovered a new mode of communication inside cells that helps bacterial pathogens learn how to evade drugs. Their findings describe how these mechanisms drive antimicrobial resistance in Listeria monocytogenes, the foodborne bacteria that causes listeriosis.

NewsAI predicts bacterial resistance to cleaning agents
With the help of artificial intelligence and DNA decoding, a new method can predict how well disease-causing bacteria such as Listeria tolerate disinfectants. This research may become a valuable weapon in the fight against harmful bacteria.

NewsTwo different sequence types of Listeria monocytogenes strains used for veterinary vaccines in Russia
Live whole-cell vaccine AUF (LWCV AUF) is used for the prevention of listeriosis in farm animals in Russian regions. A new study investigated whether the two strains used might belong to the same phylogenetic lineage and possess identical sequence types (STs).

NewsNo more antibiotics? Scientists pioneer a safer way to protect cultured meat
A new study explores the use of Random Antimicrobial Peptide Mixtures (RPMs) as a safe and effective alternative to antibiotics in cultured meat production. These synthetic peptide cocktails eliminate bacterial contamination without harming stem cell viability or contributing to antibiotic resistance.

NewsPathogens that cling to microplastics may survive wastewater treatment
Wastewater treatment fails to kill several human pathogens when they hide out on microplastics in the water, reports a new study.
-
NewsResearchers unravel mystery of dormancy in food pathogens for more effective elimination
The detection tests commonly used to check for the absence of microbes in hospitals or the agri-food industry are based on microbial growth, i.e. the laboratory cultivation of microorganisms from a sample to be checked. If no micro-organisms appear during culturing, the sample is considered safe. Source: INRAE ...

NewsNew pasteurization method wipes out pathogens on buckwheat sprouting seeds, study shows
A new pasteurization technique uses plasma, vacuum packaging and hot water to inactivate food pathogens on buckwheat seeds, cutting the risk of food poisoning outbreaks without preventing the seeds from sprouting. The technique, which reduces the total time for seed pasteurization,was developed by scientists at Kyonggi University ...
