• Electron beam reduces virus-related health risk in lettuce, spinach

    Current health-care costs in the United States associated with foodborne viruses are estimated at about $6 billion; scientists show that electron-beam irradiation can reduce the health risks in iceberg lettuce and spinach, but note that electron-beams are not meant to be used as a “stand-alone” or “clean-up” technology

  • Cold plasma reduces harmful bacteria on raw chicken

    Recent high-profile outbreaks of foodborne illness have involved contaminated fresh produce, but the most common source of harmful bacteria in food is uncooked poultry and other meat products; studies have shown that plasma could successfully reduce pathogens on the surface of fruits and vegetables without cooking them, and scientists demonstrates that plasma can be an effective method for killing pathogens on uncooked poultry

  • Understanding – and averting -- drug resistance in bacteria

    Bacterial resistance to antibiotics is growing exponentially, contributing to an estimated 99,000 deaths from hospital-associated infections in the U.S. annually; one reason that this is happening is that drug resistant proteins are transporting “good” antibiotics, or inhibitors, out of the cells, leaving them to mutate

  • Research collaboration to fight Campylobacter jejuni

    Campylobacter, primarily C. jejuni, is the third leading cause of death from foodborne infections in the world; in the United States alone, it affects nearly 2.4 million people, causes an estimated 58,000 illnesses and 200 deaths, and costs companies millions of dollars in recall losses each year

  • Invaders wreak havoc on U.S. ecosystems

    In the decade since the 9/11 attacks, DHS’ focus on combatting terrorism has left some of its core agencies ill-equipped to perform its other missions, namely the Customs and Border Protection’s (CBP) ability to prevent invasive plants and insects from entering the United States and wreaking havoc on crops

  • Portable device quickly detects pathogens in developing countries

    Two Cornell University researchers will combine their inventions to develop a handheld pathogen detector that will give health care workers in the developing world speedy results to identify in the field such pathogens as tuberculosis, chlamydia, gonorrhea, and HIV

  • Protein study to help in superbug battle

    Scientists have shed light on the way superbugs such as MRSA are able to become resistant to antibiotics; the researchers have done it by mapping the complex molecular structure of an enzyme found in many bacteria

  • Europe crops damaged by pollution crossing oceans, continents

    Pollution originating from North America is responsible for a 1.2 million ton annual loss of wheat in Europe; this is the biggest intercontinental ozone pollution-related impact on any food crop

  • New food-pathogen detection system

    A new food pathogen detection system is based on a combination of technologies involving isothermal DNA amplification and bioluminescence detection

  • Scientists offer new information for fighting flu

    Influenza is the world’s leading cause of morbidity and mortality; seasonal viruses affect up to 15 percent of the human population and cause severe illness in five million people a year; in the United States, financial losses caused by seasonal influenza are estimated to exceed $87 billion annually

  • Stealthy leprosy pathogen evades immune response

    Leprosy, one of the world’s oldest known diseases, is a chronic infectious disease that affects the skin, the peripheral nerves, the upper respiratory tract, and the eyes and can lead to disfigurement of the hands, face, and feet; scientists’ findings point to new treatment pathways for leprosy – and other infectious diseases

  • How new viruses evolve and become deadly

    Scientists demonstrate how a new virus evolves, which sheds light on how easy it can be for diseases to gain dangerous mutations; this demonstration follows recent news that scientists in the United States and the Netherlands produced a deadly version of bird flu

  • Scientists urge accelerated flu research

    The discovery by scientists that H5N1 virus could potentially be transmitted between mammals has led to fears both of misuse and of accidental release – and to requests of two leading science publication to edit and redact portions of two articles in which the findings of the research are reported; a leading specialist argues that H5N1 viruses circulating in nature may already pose a threat because influenza viruses constantly mutate and can cause pandemics

  • Farmers urge Congress to reject antibiotic restrictions in animals

    Pending bills H.R. 965 (House) and S. 1211 (Senate) would remove specific antibiotics and classes of antibiotics from animal feed; the purpose is to make sure that bacteria these antibiotics are aimed to combat do not become drug-resistant, thus endangering human health and lives; farmers and ranchers say the bills go too far

  • Federal court hears debate over California bio weapons research facility

    Earlier this month opponents of the bioweapons research center at Lawrence Livermore National Laboratory argued before a federal appeals court that government officials failed to heed a 2006 court ruling and recklessly went ahead with the research facility without considering terrorist threats
