• Factors influencing spinach E. coli contamination before harvest

    Researchers have identified a variety of factors that influence the likelihood of E. coli contamination of spinach on farms prior to harvest. They found that E. coli contamination of spinach on farms in Colorado and Texas was 172 times more likely if the produce field was within ten miles of a poultry farm, and sixty-four times more likely if irrigated by pond water.

  • Weather reports aid life-or-death decisions in Africa

    The people living in sub-Saharan Africa have a life-or-death dependency on information about the weather. Knowing when, where, and what to grow or graze animals can be the difference between a bumper harvest and facing starvation. Although sub-Saharan Africa depends more directly on rainfall than any other region on Earth, the region has the fewest number of rain monitoring stations. There are also significant delays in the time between measurements being made and the resulting data being made available.

  • Fukushima-derived radioactivity in seafood poses minimal health risks

    Researchers find that the likely doses of radioactivity ingested by humans consuming fish contaminated by radioactive radiation escaping from the debilitated Fukushima reactors fish, are comparable to, or less than, the radiological dosages associated with other commonly consumed foods, many medical treatments, air travel, and other background sources.

  • U.S. unlikely to meet its biofuel goals

    The Energy Independence and Security Act of 2007 (EISA) mandates that by 2022 the United States derive fifteen billion gallons per year of ethanol from corn to blend with conventional motor fuels. A new study says that if the climate continues to evolve as predicted by the Intergovernmental Panel on Climate Change, the United States stands little to no chance of satisfying its biofuel goals.

  • Improving “crop per drop” boosts global food security, water sustainability

    New study shows increasing crop water productivity could feed an additional 110 million people while meeting the domestic water demands of nearly 1.4 billion.

  • A majority on Earth will soon face severe, self-inflicted water shortage: scientists

    A conference of 500 leading water scientists from around the world, held last week in Bonn, issued a stark warning that, without major reforms, “in the short span of one or two generations, the majority of the nine billion people on Earth will be living under the handicap of severe pressure on fresh water, an absolutely essential natural resource for which there is no substitute. This handicap will be self-inflicted and is, we believe, entirely avoidable.”

  • Studying botulinum genome to understand botulism harm

    The toxin that causes botulism is the most potent that we know of. Eating an amount of toxin just 1,000th the weight of a grain of salt can be fatal, which is why so much effort has been put into keeping Clostridium botulinum, which produces the toxin, out of our food.

  • Illnesses in U.S. on the rise as a result of decline in foreign food inspections

    More Americans get sick every year as a result of food-borne pathogens. The reason: inspections at foreign food factories shipping food and food ingredients to the United States have declined in recent years, and border inspections of food coming into the country could be next to be reduced. Experts say this decline in inspections is especially worrisome since Americans consume more imported food – or food made with imported ingredients – every year, and foreign food production and processing facilities often do not meet U.S. sanitation and hygiene standards.

  • Horse meat in the human diet

    Horse long has been on menus in continental Europe, sold from shops that often advertise with a carved horse head on the store front.A chemist explains the testing for horse DNA in food products, and discusses the concerns about selling and eating horse meat in the United States.

  • New fertilizer can be used to grow food – but not build bombs

    Ammonium nitrate fertilizer is used in agriculture, but when mixed with a fuel such as diesel, it is highly explosive. It was used in about 65 percent of the 16,300 homemade IEDs in Afghanistan in 2012.About 1,900 troops were killed or wounded in IED attacks in 2012, 60 percent of American combat casualties. There have been more than 17,000 global IED incidents in 123 countries in the past two years. Timothy McVeigh used ammonium nitrate in Oklahoma City in 1995. Scientists have developed a fertilizer that helps plants grow but cannot detonate a bomb.

  • Volatility of food prices is still a mystery

    Riots, political instability, and a spike in malnourishment cases blighted the years 2007 and 2008, particularly in developing countries. The cause was a sudden surge in global food prices, with rice eventually rising several hundred per cent as importing countries simply could not get enough of this basic foodstuff.Food market volatility has yet to be understood, and there is no definite proof that it is due to speculators.

  • New detection test to improve food safety, bioterrorism defense

    Sales of chicken products in China plummeted recently during an outbreak of a deadly new strain of bird flu. From bird flu to mad cow disease, numerous food scares have made global headlines in recent years.Scientists develop new detection technique which wouldmake food contamination testing more rapid and accurate. The detection test could also accelerate warnings after bioterrorism attacks.

  • Interior Dept. releases progress report on U.S. Water Census

    The U.S. Interior Department issued released a report to Congress on the progress of the National Water Census. As competition for water grows — for irrigation of crops, for use by cities and communities, for energy production, and for the environment — the need for the National Water Census and related information and tools to aid water resource managers also grows. The Water Census will assist water and resource managers in understanding and quantifying water supply and demand, and will support more sustainable management of water resources.

  • Deadly wheat disease threats global food supplies

    Disease-resistant wheat developed over the past half century helped ensure steady world food supplies, but a global research team warns that without increased financial support for disease resistance research, new strains of a deadly fungal disease could leave millions without affordable access to food.

  • Invasive kudzu bugs pose greater threat than previously thought

    The invasive kudzu bug has the potential to be a major agricultural pest, causing significant damage to economically important soybean crops. Conventional wisdom has held that the insect pests will be limited to areas in the southern United States, but new research shows that they may be able to expand into other parts of the country.
