Listeria infection could be prevented with gut bacteria, study finds

Researchers have identified four species of gut bacteria that they say could protect high-risk individuals against Listeria infection.

Study reveals listeria bacteria can hide inside tissue of romaine lettuce

A Purdue University study shows that the bacteria Listeria monocytogenes can live inside the tissue of romaine lettuce, suggesting that conventional post-harvest sanitization practices might not be…

Antibiotic resistant salad

Antibiotic-resistant strains of the food-poisoning microbe Listeria monocytogenes in unprocessed salad products is not quite as widespread as scientists originally suspected.

Pathogens in cheese – researchers follow the traces of deadly bacteria

Listeria is a rod-shaped bacterium highly prevalent in the environment and generally not a threat to human health. One species however, Listeria monocytogenes, can cause listeriosis, a very dangerous disease.

Multi-State Listeria Outbreak Deaths Continue

The Listeria scare that began with a voluntary recall 14th Sept of Jensen Farms Rocky Ford-brand cantaloupes, and followed with a recall of shredded lettuce, continues to cause deaths, and has now become an economic issue for farms across California with farmers and resellers abandoning the cantaloupes even though they are perfectly safe to eat. “We can’t sell the fruit …

Mellon Scare Spreads With Listeria Found In Romaine Lettuce

The scare from the Listeria outbreak doesn’t seem to have abated yet with 2500 cartons of pre chopped and shredded Romaine Lettuce recalled in California. Whilst the bug is more likely to affect the elderly and those with weakened immune systems its still of concern to everyone especially pregnant women…

Fluorescent Test System To Hunt For Deadly Bacteria

You can’t see them, or smell them or taste them. They can be in our water and in our food, multiplying so rapidly that conventional testing methods for detecting pathogens such as E.coli, Salmonella and Listeria come too late for the tens of thousands of Canadians who suffer the ill effects of these deadly bacteria…

Cardiac Disease Risk Increased By Heart-Targeting Listeria

Certain strains of the food pathogen Listeria are uniquely adapted to infect heart tissues and may put people at a higher risk from serious cardiac disease, according to a new study published in the Journal of Medical Microbiology. Developing new diagnostic tests to identify these potentially fatal strains could protect those most at risk, such as those with heart valve replacements…

Nanoparticle Gives Antimicrobial Ability To Fight Listeria Longer

A Purdue University research team developed a nanoparticle that can hold and release an antimicrobial agent as needed for extending the shelf life of foods susceptible to Listeria monocytogenes…
