This Fast-Food Chain Is Linked to 40 Cases of Food Poisoning
Nov 19, †Ј Food poisoning can occur if food or water is contaminated with the stools (faeces) of infected cats, or if raw or undercooked meat from another animal carrying the parasite is eaten. The infection is known as toxoplasmosis. Symptoms of this type of food poisoning include swollen lymph glands and sometimes a skin rash. Toxins and chemicals. Apr 09, †Ј Food poisoning treatment.

During that time, the goal is to prevent zi255.comation is the loss of fluids and electrolytes (nutrients and minerals) your body needs. You should avoid solid foods and dairy products until the vomiting and diarrhea have passed.
Food poisoning is an illness caused by eating and drinking food or drink which is contaminated by germs or toxins. Gastroenteritis is a gut infection with diarrhoea, tummy ache and sometimes being sick vomiting. Diarrhoea is defined as 'loose or watery stools faecesusually at least three times in 24 hours'.
Food poisoning means getting sick from eating food with poisonous stuff in it. But not usually the kind of poisons used by the killer in an Agatha Christie story. Usually the poison comes from some type of germ.
Many types of germs can cause food poisoning, including bacteria, viruses and parasites. Common culprits include:. You are more likely to pick up food poisoning if you are not careful about how you store and handle food, and about what and where you eat or drink. If vomiting occurs, it often lasts only a day or so but sometimes longer.
Diarrhoea often continues after the vomiting stops and commonly lasts for several days or more. Slightly loose stools may persist for a week or so further before a normal pattern returns. Sometimes the symptoms last longer. The vomiting and diarrhoea usually start hours or a very few days after eating the infected food.
Afterwards, you often feel drained and washed out for a few days, while you regain your appetite and 'oomph'. Diarrhoea and vomiting may cause lack of fluid in the body dehydration.
Consult a doctor quickly if you suspect you are becoming dehydrated. Mild dehydration is common and is usually easily reversed by drinking lots of fluids. Severe dehydration can be fatal unless quickly treated because the organs of your body need a certain amount of fluid to function. Food poisoning is common and most of us will recognise the scenario. You ate something that looked or smelled a little dodgy, or you were abroad in a country where it isn't safe to drink the water, and you had a salad.

There are pet names for it in different parts of the world: Delhi belly, Kathmandu quickstep, Montezuma's revenge, Karachi crouch. But you can pick it up pretty much anywhere, including your own home.
Bacteria Campylobacter is the most common germ bacterium that causes food poisoning in the UK. Other germs bacteria that can cause food poisoning include:. Viruses Some germs virusessuch as norovirus or rotaviruscan contaminate food and cause food poisoning. Parasites These are another type of microbe. Parasites are living things organisms that live within, or on, another organism. Examples include cryptosporidiumEntamoeba histolytica and giardia parasites. Food poisoning caused by parasites is more common in the developing world.
In the UK, a common cause of food poisoning is Toxoplasma gondii. This is a parasite that lives in the bowels of a number of animals, including cats. Food poisoning can occur if food or water is contaminated with the stools faeces of infected cats, or if raw or undercooked meat from another animal carrying the parasite is eaten. The infection is known as toxoplasmosis. Symptoms of this type of food poisoning include swollen lymph glands and sometimes how to eat after food poisoning skin rash.
Toxins and chemicals Poisons toxins produced by bacteria can also contaminate food, as well as the bacteria themselves. For example, the bacterium Staphylococcus aureus can contaminate ice cream and its toxins can lead to food poisoning. The bacterium Bacillus cereus can contaminate rice. If contaminated rice is reheated and eaten, the toxins produced can lead to food poisoning. Certain types of fish including shark, marlin, swordfish and tuna contain high levels of the chemical mercury.
Eating these types of fish is not normally a problem for most people - it does not cause gastroenteritis or food poisoning. But pregnant women are advised to avoid eating shark, marlin and swordfish and to limit tuna.
This is because a high level of mercury can damage the developing nervous system of an unborn baby. Oily fish may be contaminated by chemicals called polychlorinated biphenyls. Again, this does not usually cause a problem or food poisoning for most people.
However, you should limit the amount of oily fish you eat in pregnancy because of possible effects of these chemicals on a developing baby. Public Health England recommends no more than two portions of oily fish a week. Note : this is a general leaflet about food poisoning. There are separate leaflets that give more details about some of the different microbes that cause how to set parental controls on my computer poisoning.
Contamination of food can occur because of problems in food production, storage or cooking. For example:. Water can become contaminated with bacteria or other microbes usually because human or animal stools faeces get into the water supply.
This is particularly a problem in countries with poor sanitation. In such countries, food may also be washed and prepared using contaminated water. So, for example, in countries with poor sanitation, you should always avoid:. Most people will recognise food poisoning from their typical symptoms.

It can also occur if raw meat is stored above ready-to-eat meals and juices from the meat drip on to the food below. See preventing food poisoning for information about reducing these risks. Food contamination is usually caused by bacteria, but it can also sometimes be caused by viruses or parasites. Some of the main sources of contamination are described below.
In the UK, campylobacter bacteria are the most common cause of food poisoning. The bacteria are usually found on raw or undercooked meat particularly poultry , unpasteurised milk and untreated water. The incubation period the time between eating contaminated food and the start of symptoms for food poisoning caused by campylobacter is usually between two and five days.
The symptoms usually last less than a week. Salmonella bacteria are often found in raw or undercooked meat, raw eggs, milk, and other dairy products. The incubation period is usually between 12 and 72 hours. The symptoms usually last around four to seven days. All of these foods should be eaten by their "use-by" dates. This is particularly important for pregnant women, because a listeria infection known as listeriosis in pregnancy can cause pregnancy and birth complications, and can result in miscarriage.
The incubation period can vary considerably, from a few days to several weeks. The symptoms will usually pass within three days. Escherichia coli, often known as E. Most strains are harmless but some can cause serious illness. Most cases of E. The incubation period for food poisoning caused by E. The symptoms usually last for a few days or weeks. Symptoms typically develop within seven days of eating contaminated food and last for up to a week. An infection caused by Shigella bacteria is known as bacillary dysentery or shigellosis.
See the topic on dysentery for more information about it. The virus that most commonly causes diarrhoea and vomiting is the norovirus. It's easily spread from person to person, through contaminated food or water.
Raw shellfish, particularly oysters, can also be a source of infection. The incubation period typically lasts hours and the symptoms usually pass in a couple of days. In young children, the rotavirus is a common cause of infection from contaminated food. The symptoms usually develop within a week and pass in around five to seven days.
In the UK, food poisoning caused by parasites is rare. It's much more common in the developing world. The symptoms of food poisoning caused by a parasite usually develop within 10 days of eating contaminated food, although sometimes it may be weeks before you feel unwell.
