The assay detected <em>L. monocytogenes</em> artificially inoculated on wild blueberries with specificity over other pathogens, the researchers reported.</p> 2013-04-12T16:40:00Z http://www.foodquality.com/details/article/4562771/Mutation_That_Increases_Listeria_Survival_Identified.html <p>A single-point mutation newly identified in the genome of <em>Listeria monocytogenes</em> increases the pathogen&rsquo;s ability to withstand temperature-related and osmotic stress, researchers in Ireland reported. The same group also described a previously unidentified twisting of<em> L. monocytogenes</em> cells into a corkscrew shape in response to increased stresses.</p> 2013-04-03T14:42:00Z http://www.foodquality.com/details/article/4155331/Norman_Ernest_Borlaug_Worked_Tirelessly_to_Solve_World_Hunger_Crisis.html <p>Nobel laureate and father of the green revolution was a food science innovator.</p> 2012-12-19T00:15:00Z http://www.foodquality.com/details/article/2785351/Key_Considerations_When_Selecting_a_Rapid_Detection_Partner.html <p>Dairy, food, and beverage manufacturers can achieve faster, more reliable microbial results with a full understanding of rapid microbial screening.</p> 2012-10-24T16:52:00Z http://www.foodquality.com/details/article/2370441/Why_Norovirus_Out-Pathogens_Salmonella_and_E__Coli.html <p>A recent report in the <em>Journal of Infectious Diseases</em> underscores why norovirus represents &ldquo;the perfect human pathogen,&rdquo; according to Aron Hall, DVM, MSPH, an epidemiologist with the CDC&rsquo;s Viral Gastroenteritis Team.</p> 2012-08-03T18:51:00Z http://www.foodquality.com/details/article/1913255/Gold_Nanoparticles_Can_Detect_Zap_Salmonella.html <p>By attaching pathogen-specific antibodies to vanishingly small gold nanoparticles&mdash;so minuscule that 25,000 would fit across the width of a human hair&mdash;scientists at Jackson State University in Mississippi can detect various strains of <em>Salmonella</em> with a simple five-minute test.</p> 2012-04-20T23:33:00Z http://www.foodquality.com/details/article/1789053/Ripeness_Plays_Role_in_Vulnerability_of_Produce_to_Salmonella.html <p>Foodborne pathogens attach to fruits in different ways depending on their ripeness, according to researchers from Imperial College London, who presented their work at the Society for General Microbiology&rsquo;s Spring Conference in Dublin, Ireland, in late March.</p> 2012-04-09T16:03:00Z http://www.foodquality.com/details/article/1721937/Microbiological_Tests_and_Kits_The_Latest_Advances.html <p>It&rsquo;s been almost a year since the E. coli outbreak that originated in Germany in May last year killed more than 40 people. The frenzy to identify the strain responsible &mdash; the relatively rare O104:H4 &mdash; helped point out the increasing need for rapid and reliable pathogen testing in the food industry.</p> 2012-04-02T12:57:00Z http://www.foodquality.com/details/article/1721467/Ozone-Treated_Water_Zaps_Infectious_Prions.html <p>Infectious prions, the lethal microbes that cause Creutzfeldt-Jakob disease in humans and bovine spongiform encephalopathy (mad cow disease) in animals, can be eradicated with a technique that has long been used to inactivate pathogens in drinking water.</p> 2012-03-31T04:53:00Z http://www.foodquality.com/details/article/1532131/Do_Nanoparticles_Affect_Digestion.html <p>Nanoparticles are routinely added to food products and used in food packaging, but the impact they might have on health is still not well understood.</p> 2012-03-09T01:56:00Z
