Food Poisoning

What is Food Poisoning?

Food poisoning is a common, yet distressing and sometimes a life-threatening problem for millions of people. It occurs most often from:

  • meat, especially undercooked mince and rolled, formed or tenderised meats
  • raw or undercooked poultry such as chicken, duck and turkey
  • raw or lightly cooked eggs including foods made from raw egg such as unpasteurised mayonnaise
  • smallgoods such as salami and hams
  • seafood
  • cooked rice not kept at correct temperatures
  • cooked pasta not kept at correct temperatures
  • prepared salads such as coleslaw, pasta salads and rice salads
  • prepared fruit salads
  • unpasteurised dairy products

People infected with foodborne organisms may be symptom-free or may have symptoms ranging from mild intestinal discomfort to severe dehydration and bloody diarrhea. Depending on the type of infection, people can even die as a result of food poisoning.

Food poisoning, also called food-borne illness, is an illness caused by eating contaminated food. Infectious organisms — including various bacteria, viruses and parasites — or their toxins are the most common causes of food poisoning.

Infectious organisms or their toxins can contaminate food at any point during its processing or production. Contamination can also occur at home if food is incorrectly handled or cooked.

Food poisoning symptoms often include headaches, stomach cramps, nausea, vomiting or diarrhea, which can start just hours after eating contaminated food. Most often, food poisoning is mild and resolves without treatment. But some cases are severe, requiring hospitalization. Other symptoms include fever, dehydration and occasionally, blood in the feces


Food Poisoning

Food poisoning is an adverse reaction to a particular substance, usually bacteria in contaminated food or water that attacks the stomach and intestines, resulting in gastrointestinal upset. Salmonella, Campylobacter jejuni, and Staphyloccocus, which affect poultry, raw meat, untreated milk, and duck and hen eggs, are some of the more common types of food poisoning. E-coli, found in undercooked meat, untreated milk, and contaminated water, is a slightly rarer cause. Norwalk virus, found in raw shellfish, salads, and contaminated water, is a common viral cause of food poisoning. In more serious cases, the bacteria may enter the lymph tracts, which carry water and protein to the blood, and the blood itself. Children, pregnant women, the elderly, and people who are already ill or have weakened immunity are particularly vulnerable to food poisoning and may get a serious infection. The symptoms of food poisoning vary quite markedly in intensity, and can range from slight to life-threatening. Most attacks are mild, with symptoms lasting between one and three days.

Please contact your doctor if diarrhea due to food poisoning continures for more than 24 hours, you have severe stomach cramps, there is blood in the feces, there is a fever of 100 degrees F or higher, or there are any signs of dehydration.


Your doctor will make a diagnosis based on the length of time elapsed between eating the contaminated food and the first sign of symptoms. Determining whether a fever is present also aids in diagnosing the type of bacteria causing the food poisoning and therefore influences the treatment.

Post-infection problems are associated with some types of food poisoning. See your doctor regarding any new onset of symptoms following an episode of food poisoning. Anyone with a compromised immune system suffering should seek medical treatment at the onset of food poisoning symptoms.

Oral rehydration solution

A home oral rehydration solution can be mixed with sugar, salt, and baking soda. This makes a solution very similar to the intravenous fluids administered at the hospital for dehydration. Mix 1 liter of filtered water, 2 tbsp of sugar, ½ tsp of salt, and ½  tsp of baking soda. Sip the solution throughout the day until urine is a normal color and urination occers four to five times a day.

Natural Treatment

  • Stay hydrated: Drink 8-12 glasses of water throughout the day to prevent dehydration. When vomiting and diarrhea occur together, make sure that water is drunk, at frequent intervals. If vomiting is a particular problem, avoid the temptation to gulp down a long glass of water quickly, however thirsty you may feel. Instead, take small sips to give yourself the best chance of keeping it down. In acute situations do not eat solid foods if you do not feel like them, but stay hydrated with water, soups, freshly pressed fruit juices, sports drinks with electrolytes, and chamomile or peppermint tea mixed with a little nutmeg. Miso broth or other hot clear broths help restore proper fluid and electrolyte balance. Give a child with food poisoning an oral electrolyte formula such as Pedialyte, availavle over the counter. Drink barley or rice water, made from 1 cup of raw grain added to 1 quart of boiling water, to soothe an inflamed stomach or intestine. Let the grain steep for 20 minutes, strain the liquid, and drink throughout the day.


  • Do not take charcoal right away: It is not wise to take charcoal immediately to stop diarrhea as this will prevent the contaminants from being excreted. You can protect yourself by taking 1 drop of eucalyptus oil in the morning and 1 drop of savory oil in the evening, both diluted in tea or juice. Charcoal has the ability to absorb substances such as parasites and bacteria, preventing them from being reabsorbed by the body. It may also be used for relieving indigestion, nausea, vomiting, diarrhea, and intestinal bloating. Take ½ cup of charcoal powder mixed with a glass of water.



  • Take a probiotic product containing at least four billion active organisms of Lactobacillus acidophilus and bifidus daily to help digestion and fight infection.


  • Alpha-lipoic acid is indicated in some reports as helpful in treating some types of food poisoning. Take 50 mg twice a day or 100 mg once a day.


  • Take 1,000 to 3,000 mg of L-glutamine, an amino acid that repairs the gut, three times a day.


  • Vitamin A may help the body to rid itself of salmonella, according to some studies, and those people that are vitamin A deficient may actually be more prone to salmonella infection. Take 25,000 to 50,000 IU a day. Do not take more than 10,000 IU of vitamin A if you are pregnant; children can take 5,000 IU a day.
  • Ginger is quite effective in helping ease the effects of food poisoning and decrease intestinal inflammation. Take 500 mg of ginger in capsule form or 1-2 cups of ginger tea a day.


  • Marshmallow root is soothing to the digestive tract. Take 500 mg in capsule form three times a day.


  •  Barberry has been traditionally used to treat diarrhea from infectious causes such as E. coli and V. cholera and therefore, may help ease this symptom in some people with food poisoning. Take 2-3 ml of tincture three times per day, or standardized extracts containing 5-10 alkaloids.


Homeopathic Remedies

Food Poisoning is a perfect example of an acute condition where homeopathic support can be of immense value in speeding-up recovery. The remedies listed below are some of the most commonly used. There are many others.

If you are not sure which remedy is best indicated in your particular case; ask your homeopath to choose the right remedy for you.


Homeopathic remedies that help with food poisoning

  • Phosphorus

If there is marked thirst for cold drinks that initially stay down, but are then vomited up as soon as they are warmed by the stomach, use phosphorus. There is a high level of anxiety when feeling nauseous that is eased by reassurance from a calming, soothing person. Diarrhea is painless but may be severe, especially in the evenings, when there is a real difficulty in controlling bowel movements.

  • Ipecac

For a particularly intense sensation of nausea that leads to episodes of vomiting that do nothing to relieve the awful sensation of sickness, even temporarily, use Ipecac. Nausea is aggravated by movement of any kind, or by stooping and bending forward. Although patients bring up frothy vomit frequently, there is an unusual lack of thirst when this remedy is helpful. The abdomen feels sensitive and distended with spasmodic colicky pains, and there is an unpleasant, constant urge to empty the bowels.

  • Arsenicum album

This and the remedy that follows are specific for situations where diarrhea and vomiting occur simultaneously. Classic symptoms include burning pains in the stomach and abdomen that are temporarily eased by small sips of warm drinks. Contact with warmth in general is very much desired (with the exception of the head and face), since there is a pervading sense of being chilled to the bone. Feelings of anxiety when ill do not respond to the strongest reassurance, and can develop into a feeling of being unable to recover. All symptoms are most intense at night.

  • Veratrum album

This is another strong candidate for treating vomiting and diarrhea that occur together. Symptoms include exhaustion to the point of prostration after vomiting and/or diarrhea. The skin appears exceptionally pale and feels clammy to the touch. There is also a characteristic thirst for cold water, which tends to be vomited up very soon after it has been drunk. Moving around intensifies that distress and intensity of nausea.

  • Constitutional remedy

A well-chosen homeopathic constitutional remedy that considers the person holistically, that is, not only the physical symptoms, but their mental and emotional states as well, will be very beneficial to any suffering from food poisoning, because it is the most individualized medicine you can get. Just think, out of more than 4,000 different remedies there will only be a handful or two that will be suited to the individual. This is precisely the reason why we have good results in homeopathic treatment. A remedy that resonates well with a person’s energy has the power to effectively support the body in its efforts to heal itself.

 Tips on preventing food poisoning

The best protection is to observe certain guidelines when it comes to food

Store food properly

Separate raw food from cooked food, and store raw food at the bottom of the fridge to avoid juices dripping down and contaminating other food. Make sure that the temperature of your fridge is below 41 degrees F and your freezer below 5 degrees F. Cover all food with lids, tin foil, or plastic wrap. Do not store food in opened tin cans.

Handle food carefully

Buy hot and cold foods at the end of your shopping trip, and keep them separated. Take your shopping home quickly and unpack it immediately. When eating out, check that serving staff use separate tongs when handling separate food types, such as meats and vegetables.

Cook food properly

Wash your hands in warm, soapy water for at least 30 seconds before preparing food. Cook poultry until the meat is white, cook hamburgers and sausages right through until their juices run clear, and cook white fish until it flakes easily with a fork. Do not eat food that is past its use-by date, and avoid food in swollen, dented leaking, or damaged cans, containers, or other packaging.
