Most people around the world have heard about the medicinal benefits of Chinese herbal remedies. These time tested traditional potions have maintained the one of the worlds largest and indeed greatest cultures for thousands of years. Today, few would dispute the benefits of herbal medicines in the hands of experienced and reputable practitioners.

In the advent of the computer age Chinese traditional medicine has gained a great deal of exposure through the Internet. Now there are a great many companies which sell herbal medicines over the Internet. Herbs, like all other organic substances are susceptible to all sorts of microbial infestations which can greatly compromise the quality of the plant and hence the product which you buy. Herbs infested with moulds, viruses or any of the many types of bacteria can loose most if not all of their beneficial medicinal properties and can even become dangerous to consume.

Herbs which are used in traditional Chinese medicine, like any other other cash crop are grown in fields or collected from the wild, they are then harvested, graded,cut to size,dehydrated, checked by quality control (hopefully), packed, stored in warehouses and finally shipped to the store where you buy them or sent directly to you if you buy via direct marketing routes. As you can see, plants used in traditional medicine go through many handling processes before they become the final product which you but. Every time the plant is handled, something of it’s original integrity and quality is lost. This is inevitable in any industry and each stage presents opportunities for cross contamination if the product is handled improperly. As with any product good manufacturing procedures (GMP) are an absolute necessity. Unfortunately, not all people who market traditional Chinese herbs are reputable manufacturers and great care must be taken in choosing which company to buy from.

Usually, the more high tech the facilities of a factory are, the higher product standards will be. Today, a number of Chinese companies are offering medicinal herbs in freeze dried form The advantages of freeze drying are that the raw materials used have to be of a high standard to ensure a stable end product. Secondly, freeze drying is a great way of preserving as many of the original qualities of the plant as possible. Thirdly, because freeze drying is a very quick process, there is no tome for bacterial or mould spores to form and oxidization is prevented. This means that from a food hygiene standpoint you are safeguarded against such micro organisms forming during usage. Fourthly, Freeze dried products deteriorate at a much slower rate than with other methods that are in use, among other things this means that the anti oxidizing properties of the plant(s) are preserved.

Freeze drying also permits the manufacturer to be very inventive during the manufacturing process. He can make blends that are intended to ensure that you the customer get a guaranteed strength of active ingredient and he can also blend different types of herbs to formulate products to make ready to use infusions for specific medical conditions. In addition, ingredients which make a product more palatable can also be added.

Some of these companies claim to have hundreds of blends in their product range which cover a great many medical requirements. If you intend to use traditional Chinese medicine I would strongly recommend that you investigate the possibilities offered by freeze dried technology.

The world continues to watch in despair as the honey industry continues to tale huge knocks. In recent weeks vast quantities of honey imported from China to the USA were stopped at US ports after checks showed that the honey contained low to moderate quantities of Chloramphenicol, an antibiotic which is not approved for ingestion.

Food spoilage is really nothing more than a natural deterioration of organic matter. Everything in nature has to be broken down so that it can once again become part of the composition of soil. All of the various natural processes that participate in the spoilage of organic material are ultimately directed toward this aim.

What is listeriosis?
Listeriosis is a bacterial infection caused by the bacterium Listeria monocytogenes. Until several years ago it was thought that this bacteria only infected animals but it is now accepted that humans are also at risk from this disease. While many bacteria are generally seen to infect specific locations within the human body, Listeria may infect many different locations, such as the brain or the spinal cord membranes or the bloodstream.

Classification:
L. monocytogenes is a gram positive, non-spore forming, motile, facultatively anaerobic, rod shaped bacterium. It is catalase positive, oxidase negative, and expresses a Beta hemolysin which causes destruction of red blood cells. This bacterium exhibits characteristic tumbling motility when viewed with light microscopy. [6] Although L. monocytogenes is actively motile by means of peritrichous flagella at room temperature (20-25C), the organism does not synthesize flagella at body temperatures (37C). [7]

Who gets listeriosis?
Anyone can get this disease, but those at highest risk for serious illness from this bacterium are newborns, the elderly, people with weakened immune systems, and pregnant women. Healthy adults and children occasionally get infected with Listeria, but they rarely become seriously ill. Listeria Monocytogenes is classified as an intracellular paracite. This means that it invades and lives within cells of the body thereby managing to evade the body’s immune system. Infection by as few as 1000 individual bacteria is considered enough for the disease to take hold. When listeric meningitis occurs, the overall mortality may reach 70%; from septicemia 50%, from perinatal/neonatal infections greater than 80%. In infections during pregnancy, the mother usually survives.

When do Listeria infections occur?
Infections occur throughout the year. Although most cases occur sporadically, food-borne outbreaks of this disease do frequently occur. Poor food hygiene and poor personal hygiene conditions are responsible for many of the recently recorded outbrakes.

How is listeriosis spread?
Listeria bacteria are widely distributed in nature and can be found both in water and soil. Infected animals may also serve as sources of contamination. Unlike other organisms, Listeria can be spread through several different methods. Ingestion or food-borne transmission of the organism, such as through the ingestion of unpasteurized milk or by the eating of contaminated vegetables, is often a source of many cases. In newborn infections, the organism can be transmitted from mother to fetus in utero, or directly to the fetus at the time of birth through the contact of the fetus’ blood supply with that of the mothers. Direct contact with the organism can cause lesions on the skin.

What are the symptoms of listeriosis?
Because listeriosis can affect many different parts of the body, the symptoms vary. For meningoencephalitis, the onset can be sudden with fever, intense headache, nausea, vomiting and signs of meningeal irritation. In other body locations, various types of lesions at the site of infection are the primary symptom. In most cases, Listeria infection causes fever and influenza-like symptoms resembling a host of other illnesses.

How soon after exposure do symptoms of listeriosis appear?
Listeriosis has an extremely variable incubation period. It can range from 3 to seventy days, but symptoms usually will typically appear within a month of infection.

How is listeriosis diagnosed?
Specific laboratory tests are the only way to effectively identify this disease. Since many cases may be mild, the disease may be much more common than is realized.

Are there any unusual features of listeriosis?
Listeria infections are a significant risk for pregnant women, who may not experience obvious symptoms. Infection of the fetus can occur before delivery and can cause abortion as early as the second month of pregnancy, but more often in the fifth and six months. An infection later in pregnancy may cause exposure during birth, sometimes resulting in infection of the newborn child which may be fatal.

Does past infection with Listeria make a person immune?
Past infection does not appear to produce immunity.

What is the treatment for Listeria infection?
Several antibiotics are effective against this organism. Ampicillin, either on it’s own or in combination with other types of antibiotics, is frequently used.

What can be done to prevent the spread of Listeriosis?
Since the organism is widly distributed throughout nature, basic sanitary measures such as only using pasteurized dairy products, by only eating cooked meats and washing hands thoroughly prior to the preparation of foods offer the best protection against infection by this disease.

In addition, the following recommendations are for persons who are categorized to be at high risk of infection, such as pregnant women, the elderly and persons with compromised immune systems:

Do not eat hot dogs, luncheon meats, or deli meats, unless they are reheated until they are steaming hot.
Avoid getting the liquid from hot dog packages onto other foods sources, utensils, and food preparation surfaces, and remember to wash hands after handling hot dogs, luncheon meats, and deli meats.
Do not eat soft cheese products such as feta, Brie, and Camembert, blue-veined cheeses, or Mexican-style cheeses such as queso blanco, queso fresco, and Panela, unless they clearly state they are made from pasteurized milk written on the labelling of the product.
Do not eat chilled pâtés or meat spreads. Canned or shelf-stable pâtés and meat spreads can be eaten.
Do not eat refrigerated smoked seafood, unless it is contained in a cooked dish, such as a casserole. Refrigerated smoked seafood, such as salmon, trout, whitefish, cod, tuna or mackerel, is most often labeled as “nova-style,” “lox,” “kippered,” “smoked,” or “jerky.” The fish is found in the refrigerator section or sold over deli counters of grocery stores and delicatessens and supermarkets. Canned or shelf-stable smoked seafood may be eaten.

Today’s blog entry is going to be a bit different from the type of article I have written up to this point but I hope that you will find it interesting nonetheless. We all need food to survive and we need a varied, balanced diet of good quality food to survive and prosper. In this modern world that we live in we tend to see food as a mere commodity, something that we need, that we can’t do without. Most of us shop very differently to the way our grandparents would have shopped not so many years ago. We scurry around supermarkets piling products into a huge metal basket on wheels. Our food is stuffed into plastic containers, tin cans, foil wrappings and waxed cardboard with little thought to what the substances that those packagings are actually doing to our food.

As a spiritual person I am very much aware that our food has within it the spirit of the beings that lived before us and now make up the matter which we call earth. Food has dynamic energy and still interacts with it’s surroundings both during it’s growth phase and after it has either been harvested of slaughtered. To my intense disappointment and distress our food is not shown the respect it deserves from many of those who grow it and process it.

One thing that we need to remember it that the energy that is held within our food goes into our bodies and is assimilated into our body tissues for energy, growth and maintenance. The quality of the food we eat in terms of energy has direct bearing as per the quality of the end product that we are able to produce. This could for structural purposes, for cognitive purposes, for defence purposes and a range of other things.

For many of us the option of owning our own private vegetable patch and private orchard is not really within the realms of possibility but farmers markets are popping up all over the place that offer produce that has been grown organically with more positive emotion, slaughtered more humanely with far less stress and packed and processed in a much more tranquil and positive surrounding by people who truly love what they do. Processed products on offer in farmer’s markets can incluse produce such as could breads,cheese, pickles, jams, cakes, pies, sausages, hams and many many other types of pre prepared produce.

Similarly, restaurants can be very stressful places, particularly in the kitchen area. Although a chef may strive to present you with a dish that is a veritable work of art, the human interaction inside the kitchen is very often very stressful and generally negative with a lot of shouting, cursing, sometimes violence, humiliation, emotional castration, jealousy, hate, resentment, exploitation, degredation, disrespect and more. Believe me, I have worked in quite a few kitchens and I have seen a few things.

The intent that the chef has in creating his dish is spoiled and cancelled out by the general ambiance with the kitchen and the restaurant. Personally I can sense these energies and I will refuse to eat in such places but in circumstances where people might get offended if I refuse point blank, I make sure that I don’t come back to the same restaurant for a very long time.

I like to research where I eat. I look at the produce they use, how it delivered, how the management treat the kitchen staff including the waiters and when I am satisfied that the energy flowing within an establishment is one with which I revere, Then I will eat there. Food with good energy feeds your spirit as well as hunger. You feel elated, not in the egotistical sense but in a way that spreads to every corner of your being.

By saying a blessing or prayer quietly to yourself before eating the food in front of you you are greatly restoring good energy within the food you eat. The energy of the spirits within the food will understand what you desire of it and will not let you down. The reason for this is that you could be helping a spirit on its journey onward into eternity by giving it direction. In this way the energy will not remain stuck and confused within you. May everything you eat feed your body soul and spirit and give your life quality and purpose.

Viruses change the structure of their cell walls through mutations. This is part of the evolutionary success of viruses. The sheer numbers by which they replicate themselves leaves every statistical possibility for viral mutations to occur.

Below you will find the link for an article which to my mind is of tremendous importance in the food hygiene world. Recent pioneering research has shown bacterial defence mechanisms at the disposal of the bacterium Salmonella Enterica which consufe the body’s defence mechanisms and causes them to recognize the bacterium as part of the “self”. These mechanisms have eluded scientists until now.

This gripping article raises many new questions. Is this a quality that the bacterium always had but remained undiscovered? Is it a new defence strategy that the bacterium has produced? Will there be new implications to the capability of this bacerium and is this the first of a new string of virulent bacterial qualities with which scientists will have to contend? Read the article by following the link below:

Have you ever seen a strawberry that looks bright red and mushy? Although it doesn’t look mouldy or rotten it is clear that the strawberry has come to the end of it’s useful life. Is the strawberry bad to eat? Personally, I think that strawberries at this stage are at the height of their flavor
