...loganberry (http://www.specialtyproduce.com). The sprouting process encourages the rapid growth of microorganisms that reach very high numbers in the finished product (Fu et al., 2000). Seed sprouting provides an excellent environment for the growth of many types of organisms. The release of nutrients from the sprouting seeds, the moisture resulting from the irrigation process, the aerobic conditions, pH and temperatures favorable to mesophiles all contribute to the rapid expansion of microbial population, including food pathogens, during sprouting. Population as high as 109 CFU/g have been reported in sprouts obtained from retail stores (Patterson et al, 1980, Prokopowich et al, 1991). Many published studies have shown that pathogenic bacteria not only survive but can also grow on sprouts under favorable conditions (Portnoy et al., 1976, Harris et al., 1986, Steinbruegge et al., 1988, Abdoul-Raouf et al., 1993, and Farber et al., 1998).

...Bad Bug Book Handbook of Foodborne Pathogenic Microorganisms and Natural Toxins Introduction Food safety is a complex issue that has an impact on all segments of society, from the general public to government, industry, and academia. The second edition of the Bad Bug Book, published by the Center for Food Safety and Applied Nutrition, of the Food and Drug Administration (FDA), U.S. Department of Health and Human Services, provides current information about the major known agents that cause foodborne illness. The information provided in this handbook is abbreviated and general in nature, and is intended for practical use. It is not intended to be a comprehensive scientific or clinical reference. Under the laws administered by FDA, a food is adulterated if it contains (1) a poisonous or otherwise harmful substance that is not an inherent natural constituent of the food itself, in an amount that poses a reasonable possibility of injury to health, or (2) a substance that is an inherent natural constituent of the food itself; is not the result of environmental, agricultural, industrial, or other contamination; and is present in an amount that ordinarily renders the food injurious to health. The first includes, for example, a toxin produced by a fungus that has contaminated a food, or a pathogenic bacterium or virus, if the amount present in the food may be injurious to health. An example of the second...

Pien, MD, MPH,† and Jon B. Suzuki, DDS, PHD, MBA‡ isphosphonates (BPs) are a pharmacologic class of synthetic analogs of inorganic pyrophosphate that has an affinity for calcium.1 They are used in the treatment of various malignant and benign metabolic conditions, such as hypercalcemia of malignancy; Paget’s disease of bone; multiple myeloma; and metastases from distant sites such as breast, thyroid, prostate glands, and lung. The oral form of BPs is indicated in the management of osteoporosis, fibrous dysplasia, and most recently, osteogenesis imperfecta in the pediatric population.2,3 Currently, there are 5 bisphosphonates in clinical use: alendronate (Fosamax; Merck, Whitehouse Station, NJ), risedronate (Actonel; Proctor & Gamble Pharmaceuticals, Cincinnati, OH), ibandronate (Boniva; Roche Pharmaceuticals, Nutley, NY), zoledronate (Zometa; Novartis Pharmaceuticals, East Hanover, NJ), and pamidronate (Aredia; Novartis Pharmaceuticals). All 5 medications differ in their binding affinity to bone, potency, and duration.2–5 B Osteonecrosis of the jaws (ONJ) is a condition characterized by necrotic exposed bone in the jaws of patients receiving intravenous or oral bisphosphonate therapy. A review of the medical and dental literature reveals that the pathoetiology of ONJ remains...

...own right, as a light which has served to illuminate man’s place in the uni-verse, and as the source of understanding of man’s own nature” —John F. Kennedy (1917–63) The President of America The bacterium Escherichia coli INTRODUCTION AND SCOPE MICROBIOLOGY is a specialized area of biology (Gr. bios-life+ logos-to study) that concerns with the study of microbes ordinarily too small to be seen without magnification. Microorganisms are microscopic (Gr. mikros-small+ scopein-to see) and independently living cells that, like humans, live in communities. Microorganisms include a large and diverse group of microscopic organisms that exist as single cell or cell clusters (e.g., bacteria, archaea, fungi, algae, protozoa and helminths) and the viruses, which are microscopic but not cellular. While bacteria and archaea are classed as prokaryotes (Gr. pro-before+ karyon-nucleus) the fungi, algae, protozoa and helminths are eukaryotes (Gr. eu-true or good+ karyon-nucleus). Microorganisms are present everywhere on earth, which includes humans, animals, plants and other living creatures, soil,water and atmosphere. Microorganisms are relevant to all of our lives in a multitude of ways. Sometimes, the influence of microorganisms on human life is beneficial, whereas at other times, it is detrimental. For example, microorganisms are required for the production of bread, cheese, yogurt, alcohol, wine, beer, antibiotics (e.g., penicillin, streptomycin, chloramphenicol), vaccines, vitamins,...

...Lichen /A lichen is a composite organism that emerges from algae[->0] or cyanobacteria[->1] (or both) living among filaments of a fungus[->2] in a mutually beneficial (symbiotic[->3]) relationship.[1][2][3] The whole combined life form has properties that are very different to properties of its component organisms. Lichens come in many colors, sizes, and forms. The properties are sometimes plant-like, but lichens are not plants. Lichens may grow like a tiny, leafless, branching shrub (fruticose[->4]), like it has leaves (foliose[->5]), like a crust of paint on a surface (crustose[->6]),[4] or have other growth forms.[5] A macrolichen is a lichen that is either bush-like or leafy. A microlichen is everything else.[1] Here, "macro" and "micro" do not refer to size, but to the growth form.[1] Common names for lichens[->7] may contain the word "moss" (e.g., "Reindeer moss[->8]", "Iceland moss[->9]"), and lichens may superficially look like and grow with mosses, but lichens are not related to mosses or any plant.[3]:3 Lichens don't have roots that absorb water and nutrients like in plants.[6]:2 Instead they produce their own food from sunlight, air, water, and minerals in their environment.[7] They are not parasites[->10] on the plants they may grow on, but only use them as a substrate to grow on or in. Lichens occur from sea level[->11] to high alpine[->12] elevations, in a very wide range of environmental conditions, and can grow on almost any surface.[7] Lichens are abundant...

...What is Microbiology? Microbiology is the study of organisms too small to be seen with the naked eye. Originally, emphasis was placed on harmful micro organisms which cause disease or spoilage of beverages and food, but it is now recognized that many microbes have essential roles in our ecosystem or can be used to accomplish beneficial tasks. Human history is full of examples of major devastations caused by bacteria and viruses. Some of these historically important diseases still occur, such tuberculosis and yellow fever. Microorganisms are evolving to cause new infectious disease problems such as Lyme disease and AIDS, which capture public attention. Control and eradication of infectious diseases remain important goals of many microbiologists. The recognition that microorganisms were responsible for what was earlier thought to be "spontaneous generation" opened the door to industrial (pharmaceutical, chemical, energy) and food microbiology, technologies which contribute substantially to today's way of life. Microorganisms in soil and water are essential in the transformation of carbon, nitrogen, oxygen, sulfur and iron to products needed by plants and animals. In various ways, microbes participate in environmental cycling and degradation and global change. In the last few decades, microorganisms have been recognized as ideal model systems for the study of basic biological processes. More recently, microbiologists have brought an exciting dimension to the study of biology...

...http://cls.casa.colostate.edu/transgeniccrops/what.html What Are Transgenic Plants? A transgenic crop plant contains a gene or genes which have been artificially inserted instead of the plant acquiring them through pollination. The inserted gene sequence (known as the transgene) may come from another unrelated plant, or from a completely different species: transgenic Bt corn, for example, which produces its own insecticide, contains a gene from a bacterium. Plants containing transgenes are often called genetically modified or GM crops, although in reality all crops have been genetically modified from their original wild state by domestication, selection and controlled breeding over long periods of time. On this web site we will use the term transgenic to describe a crop plant which has transgenes inserted. Image:Results of insect infestation on Bt (right) and non-Bt (left) cotton bolls. Source: USDA | Why Make Transgenic Crop Plants? A plant breeder tries to assemble a combination of genes in a crop plant which will make it as useful and productive as possible. Depending on where and for what purpose the plant is grown, desirable genes may provide features such as higher yield or improved quality, pest or disease resistance, or tolerance to heat, cold and drought. Combining the best genes in one plant is a long and difficult process, especially as traditional plant breeding has been limited to artificially crossing plants within the same species or with closely related...

EFSA Scientific Report (2009) 231, 1-107 © European Food Safety Authority, 2009 Review of the potential health impact of β-casomorphins and related peptides SUMMARY Proteins are a very diverse family of large organic compounds involved in many important biological processes. Following their enzymatic hydrolysis during food processing or digestion, proteins may release fragments from their primary amino acid sequence. These fragments are called peptides, and many of them are known to be physiologically active. The possible beneficial effects of bioactive peptides have attracted increasing interest in recent years. On the other hand, there are also reports suggesting that some food-derived peptides might adversely affect human health. Among these, β-casomorphin-7 (BCM7), a peptide sequence present in the milk protein β-casein, has been suggested to...
