• Bacteria designed for sleuthing

    Seven Cambridge University undergraduates spent the summer of 2009 genetically engineering bacteria to secrete a variety of colored pigments, visible to the naked eye; they designed standardized sequences of DNA, known as BioBricks, and inserted them into E. coli bacteria — so the bacteria can now change its color to red, yellow, green, blue, brown, or violet; the bacteria can be programmed to do useful things, such as indicate whether drinking water is safe by turning red if they sense a toxin; other uses for the design bacterium include monitoring food additives, patenting issues, personalized medicine, terrorism, and new types of weather

  • How safe is Kansas bio lab from twisters?

    DHS officials say they are confident that the proposed bio-defense lab in Manhattan, Kansas, located in the heart of tornado alley, is capable of withstanding a direct hit from a powerful twister; engineers have hardened the $650 million National Bio and Agro-Defense Facility (NBAF) to withstand wind speeds of up to 230 miles per hour; but critics of the planned facility argue that the new standards are inadequate and that the facility must be further reinforced to ensure that in the event of a natural disaster the deadly pathogens and viruses stored there are not spread

  • Germany struggles to find source of deadly E.Coli outbreak

    German health officials struggling to find the source of deadly E.Coli outbreak suffered another setback when Spanish cucumbers were found to have been incorrectly declared the source of the infections; so far seventeen people have died and more than 1,500 Europeans have been sickened by a rare strain of enterohemorrhagic E. Coli (EHEC); eighty new cases were reported in Hamburg between Monday and Tuesday alone and hospitals are treating 110 patients critically ill with hemolytic uremic syndrome (HUS); the current outbreak has disproportionately affected women, and health officials are struggling to understand why; health officials have urged to not purchase any vegetables declared as potentially dangerous

  • Foot-and-mouth disease control measures could be reduced

    A new study of foot-and-mouth disease shows that cattle afflicted with the virus are only infectious for a brief window of time — about half as long as previously thought; this finding suggests that the controversial control measures used to halt the disease’s spread, such as killing large numbers of livestock, could be reduced

  • A "whole-system redesign" of U.S. agriculture

    Transformative changes in markets, policy, and science, rather than just incremental changes in farming practices and technology, will be critical if the United States is to achieve long-term sustainability in agriculture, according to a nationwide team of agriculturists that includes a University of California, Davis, animal scientist

  • U.S. agriculture escaped impacts of global warming -- for now

    Global warming is likely already taking a toll on world wheat and corn production, according to a new study led by Stanford University researchers, but the United States, Canada and northern Mexico have largely escaped the trend; the researchers found that global wheat production was 5.5 percent lower than it would have been had the climate remained stable, and global corn production was lower by almost 4 percent; Global rice and soybean production were not significantly affected

  • Risk of agroterrorism growing

    The United States imports so much of its food and food ingredients from other countries, that terrorists have many more opportunities to harm Americans and damage the U.S. economy; a high FDA official said that increased U.S. attention to the issue and questions over whether hostile actors have the technical capacity to mount such an attack notwithstanding, the likelihood of being poisoned by intentionally contaminated food is growing

  • Information sharing seen as public health "game changer"

    Public health officials are pushing for the creation of shared databases that contain electronic health records (EHRs) to help combat infectious diseases and stop epidemics; a CDC official pointed to the positive impact that electronic health information exchanges (HIE) have on public health; during the 2003 SARS outbreak, Milwaukee helped establish a four-state network that automatically detected new cases of SARS based on electronic reports from local hospital emergency rooms; manual reporting of test results is a slow process, but with the use of electronic reporting public health officials can now quickly identify epidemics and pandemics as they occur

  • Drug resistant salmonella found in recalled turkey burgers

    Last week the Centers for Disease Control and Prevention (CDC) announced that investigators have determined that ground Jennie-O turkey burgers have been contaminated with a drug resistant strain of Salmonella; the infection from the contaminated burgers was first detected on 27 December 2010 and has infected twelve people in ten states; a recall has been issued for nearly twenty-seven tons of the infected burgers; the Hadar strain of Salmonella, is resistant to most antibiotics complicating treatment options and increasing the chances of hospitalization; CDC investigators say they are still examining the case and may issue further recalls on raw turkey products

  • UN warns of potential food crisis

    A UN Food and Agriculture Organization official warned that countries are not doing enough to increase food production to meet rising demand and that the world could be headed for a global food crisis; global food production must rise by 70 percent in order to meet the estimated demand for food; food prices have already soared in recent months and in 2010 food prices increased by 25 percent; rising prices sparked food riots in Egypt and Tunisia, which contributed to the overthrow of their governments; large disasters and droughts have significantly reduced crop yields across the world; as supply has fallen, demand has spiked due to population growth and increased use of food to manufacture biofuels

  • Border agents intercept "destructive" Pakistani insects in Oakland

    The Khapra beetle, which is native to India, can eat its way through up to 70 percent of grain stores to which it has access; it was eradicated in the United States in 1966, and has been subject to federal quarantine since then; U.S. border agents in the Port of Oakland discover — and destroy — the larva in a shipment from Pakistan

  • Countries closely monitor Japanese food for radiation

    On Saturday, Japan announced that radiation was detected in spinach and milk produced near the Fukushima nuclear plant; the levels were low enough to not pose a long-term threat to human health, but they were above the national safety level, so the Japanese government has stopped sales of food products from near the damaged plant; countries importing food products from Japan are on alert

  • Climate change linked to food safety, cost

    Changing climate could make food more dangerous, add to the malnourishment of millions, and change even what we eat; for every degree the ambient temperature rises above 6 degrees Celsius — or 43 degrees F — temperature in an area, the occurrence of food-borne salmonella poisoning increases by 12 percent; drought can cause a loss in plant vigor, making plants more susceptible to disease; floods and heavy rains favor the growth of fungal pathogens on leaves, and many disease-causing organisms can spread in changing wind currents

  • Common clam to help clean oil-filled waters

    Clams are bottom-dwelling filter feeders, obtaining nutrients by filtering the water around them; researchers at Southeastern Louisiana University are studying the lowly Rangia clam to determine whether the organism can contribute to helping clean oil-polluted waters

  • Drought in China threatens wheat crop and send global prices soaring

    UN Food and Agriculture Organization (FAO) warned that a severe drought was threatening China’s wheat crop and could result in shortages of drinking water; analysts fear that wheat prices could soar even higher if China were to begin importing large quantities of food to feed more than a billion hungry mouths; wheat prices are already at record highs and have sparked food related protests around the world; surging prices are partially responsible for Egypt and Tunisia’s recent mass uprisings; China’s Shandong province, a major agricultural region, has only received fifteen percent of its normal rain levels; in dire terms Chinese state media reported that “land is drying out, and the crops are dying”
