...related E. coli poisoning. Until Wednesday, investigators at the CDC and the Food and Drug Administration (FDA) had only suspected that fresh, bagged spinach had caused nearly 150 people to fall ill, and led to one death, from the bacterial infection. Researchers had not been able to trace the bacteria to fresh spinach until they tested one of several opened bags of the leafy vegetable from the homes of sickened people. DNA fingerprinting confirmed not only the presence of E. coli, but also linked the bacteria found on the spinach to the same ones isolated from patients. This new information...
...originates from the feces of people or animals, a team from the FDA is inspecting sanitation procedures used both in the fields and in processing plants, and looking into water-quality logs and even weather patterns, to determine if flooding or poor drainage caused contaminated runoff to bring the bacteria into contact with produce...
...says. Depending on how long the produce remained in the ground, says Doyle, the bug stuck to the food for as long as 140 days. That's well beyond the period at which it would be harvested - meaning that if the produce isn't treated and cleaned properly, the bacteria have a good chance of hitching a ride all the way to a salad plate...
...Even more disturbing are recent studies showing that the bacteria may not be content to just live on the surface of produce, and may actually set up shop inside plant tissues, making them impossible to eliminate with a simple dousing in a chlorine bath, the current way that most fresh produce is cleaned. Eric Triplett, chair of microbiology and cell science at University of Florida, has published two studies documenting the ability of bacteria like salmonella to travel into a plant through its root system. "We just inoculate the roots and up they go, they fully colonize all over...
...carbon dioxide in the atmosphere. Thus, because carbon dioxide is a waste product, hydrogen cars recreate the same problem that they are advertised to sidestep: greenhouse gas emissions, which the balance of scientific evidence suggests lead to global warming. More environmentally friendly methods of generating hydrogen, such as coaxing bacteria to turn water alone into hydrogen, are still largely in the exploratory phase...
