Staphylococcal food poisoning occurs after food such as meat products, cold meats, milk, custard and egg products becomes contaminated before or after cooking, usually through incorrect handling by humans who carry S. aureus. The bacteria produce an ENTEROTOXIN which causes the symptoms of food poisoning 1–8 hours after ingestion. The toxin can withstand heat; thus, subsequent cooking of contaminated food will not prevent illness.
Heat-resistant strains of Cl. perfringens cause food poisoning associated with meat dishes, soups or gravy when dishes cooked in bulk are left unrefrigerated for long periods before consumption. The bacteria are anaerobes (see ANAEROBE) and form spores; the anaerobic conditions in these cooked foods allow the germinated spores to multiply rapidly during cooling, resulting in heavy contamination. Once ingested the bacteria produce enterotoxin in the intestine, causing symptoms within 8–24 hours.
Many di?erent types of Salmonella (about 2,000) cause food poisoning or ENTERITIS, from eight hours to three days after ingestion of food in which they have multiplied. S. brendeny, S. enteritidis, S. heidelberg, S. newport and S. thompson are among those commonly causing enteritis. Salmonella infections are common in domesticated animals such as cows, pigs and poultry whose meat and milk may be infected, although the animals may show no symptoms. Duck eggs may harbour Salmonella (usually S. typhimurium), arising from surface contamination with the bird’s faeces, and foods containing uncooked or lightly cooked hen’s eggs, such as mayonnaise, have been associated with enteritis. The incidence of human S. enteritidis infection has been increasing, by more than 15-fold in England and Wales annually, from around 1,100 a year in the early 1980s to more than 32,000 at the end of the 1990s, but has since fallen to about 10,000. A serious source of infection seems to be poultry meat and hen’s eggs.
Although Salmonella are mostly killed by heating at 60 °C for 15 minutes, contaminated food requires considerably longer cooking and, if frozen, must be completely thawed beforehand, to allow even cooking at a su?cient temperature.
Enteritis caused by Campylobacter jejuni is usually self-limiting, lasting 1–3 days. Since reporting of the disease began in 1977, in England and Wales its incidence has increased from around 1,400 cases initially to nearly 13,000 in 1982 and to over 42,000 in 2004. Outbreaks have been associated with unpasteurised milk: the main source seems to be infected poultry.
ESCHERICHIA COLI O157 was ?rst identi?ed as a cause of food poisoning in the early 1980s, but its incidence has increased sharply since, with more than 1,000 cases annually in the United Kingdom in the late 1990s. The illness can be severe, with bloody diarrhoea and life-threatening renal complications. The reservoir for this pathogen is thought to be cattle, and transmission results from consumption of raw or undercooked meat products and raw dairy products. Cross-infection of cooked meat by raw meat is a common cause of outbreaks of Escherichia coli O157 food poisoning. Water and other foods can be contaminated by manure from cattle, and person-to-person spread can occur, especially in children.
Food poisoning associated with fried or boiled rice is caused by Bacillus cereus, whose heat-resistant spores survive cooking. An enterotoxin is responsible for the symptoms, which occur 2–8 hours after ingestion and resolve after 8–24 hours.
Viruses are emerging as an increasing cause of some outbreaks of food poisoning from shell?sh (cockles, mussels and oysters).
The incidence of food poisoning in the UK rose from under 60,000 cases in 1991 to nearly 79,000 in 2004. Public health measures to control this rise include agricultural aspects of food production, implementing standards of hygiene in abattoirs, and regulating the environment and process of industrial food production, handling, transportation and storage.... food poisoning
For the diagnosis of true food allergy, it is necessary to demonstrate that there is a reproducible intolerance to a speci?c food; also, that there is evidence of an abnormal immunological reaction to it. Occasionally the allergic response may not be to the food itself but to food contaminants such as penicillin, or to food additives such as tartrazine. There may also be reactions to foods which have pharmacological effects, such as ca?eine in strong co?ee or histamine in fermented cheese, or such reactions may be due to the irritant e?ect on the intestinal mucosa (especially if it is already diseased) by, say, highly spiced curries.
Testing blood and skin for food allergy is beloved of some alternative practitioners but, in practice, the results of tests do not necessarily agree with what happens when the food is taken. Therefore, a careful history is as useful as any test in making a diagnosis.... food intolerance
Symptoms. Tremors, restlessness, nausea and sleep disturbance. The greater potency of the drug, the higher the rebound anxiety. Many drugs create stress, weaken resistance to disease, tax the heart and raise blood sugar levels.
Drugs like Cortisone cause bone loss by imperfect absorption of calcium. Taken in the form of milk and dairy products, calcium is not always absorbed. Herbs to make good calcium loss are: Horsetail, Chickweed, Slippery Elm, Spinach, Alfalfa.
Agents to calm nerves and promote withdrawal may augment a doctor’s prescription for reduction of drug dosage, until the latter may be discontinued. Skullcap and Valerian offer a good base for a prescription adjusted to meet individual requirements.

Notes. “Do not withdraw: insulin, anticoagulants, epileptic drugs, steroids, thyroxin and hormone replacement therapy (the endocrine glands may no longer be active). Long-term tranquillisers e.g., Largactil or any medicament which has been used for a long period. Patients on these drugs are on a finely-tuned medication the balance of which may be easily disturbed.” (Simon Mills, FNIMH)

opiates such as cocaine and morphine, amfetamine drugs, and barbiturate drugs. controlled trial A method of testing the effectiveness of new treatments or comparing different treatments. In a typical controlled drug trial, 2 comparable groups of patients suffering from the same illness are given courses of apparently identical treatment. However, only one group receives the new treatment; the second control group is given a placebo. Alternatively, the control group may be given an established drug that is already known to be effective. After a predetermined period, the 2 groups are assessed medically. Controlled trials must be conducted “blind’’ (the patients do not know which treatment they are receiving). In a “double-blind’’ trial, neither the patients nor the doctors who assess them know who is receiving which treatment. contusion Bruising to the skin and underlying tissues from an injury. convalescence The recovery period following an illness or surgery during which the patient regains strength before returning to normal activities.... controlled drug
The interaction may take place:
(1) Prior to absorption or administration – for example, antacids bind tetracycline in the gut and prevent absorption.
(2) By interfering with protein binding – one drug may displace another from binding sites on plasma proteins. The action of the displaced drug will be increased because more drug is now available; for example, anticoagulants are displaced by analgesics.
(3) During metabolism or excretion of the drug – some drugs increase or decrease the activity of liver enzymes which metabolise drugs, thus affecting their rate of destruction; for example, barbiturates, nicotine, and alcohol all activate hepatic enzymes. Altering the pH of urine will affect the excretion of drugs via the kidney.
(4) At the drug receptor – one drug may displace another at the receptor, affecting its e?cacy or duration of action.... drug interactions

Preservatives, such as sodium nitrate, are added to food to control the growth of bacteria, moulds, and yeasts. Other additives, such as antioxidants, improve the keeping quality of food by preventing undesirable changes (they stop rancidity in foods containing fat, for example). Additives that improve texture include emulsifiers, stabilizers, thickeners, and gelling agents. Appearance and taste are improved by the use of colourings, flavourings, sweeteners, and flavour enhancers. Artificial sweeteners, such as saccharin, may be used instead of sugar, especially in products for diabetics or slimmers.
Certain additives may produce an allergic reaction in some people, and some are thought to be a factor in behavioural problems in children.... food additives
