Food can become contaminated at any stage during its production, processing or cooking. Some of the main sources of contamination are described below.
Most of us are familiar with chicken or meat food poisoning and have either suffered from it ourselves or know of people who have done. But how many people do you know who have suffered from food poisoning caused by contaminated pork?
When food poisoning cases are reported in the media they have often been caused by people eating infected chicken or meat. The reasons for these include food which has not been cooked according to instructions, unhygienic handling or cross contamination.
This equally applies to pork. These roundworms live as a series of cysts which contain larvae within raw or undercooked pork and are able to pass into the human body when this pork is eaten. These cysts pass through the digestive system where stomach acid causes them to hatch out the larvae which then develop into fully grown roundworms.
These roundworms are harmful to the digestive system, but in particular, they infect bodily tissues which cause a whole range of problems within the body. These problems can last for up to two months following the initial consumption. These roundworms will eventually leave the body via the gastrointestinal tract but will cause a range of health problems before they do so.
Symptoms of trichinosis These appear in two stages: In the first stage, symptoms include severe abdominal pain, nausea and diarrhoea. This diarrhoea usually lasts for a couple of days before clearing up by itself.
These initial symptoms occur as a result of the roundworms entering the digestive system and infecting the tissues within that system. The second stage is characterised by fever, aches and pains in the muscles and joints, chills and itching.
This occurs 2 to 8 weeks later and as a result of the roundworms infecting skeletal muscle cells. Diagnosing trichinosis This is not always easy to diagnose, especially in the first stage unless the person concerned mentions that they have eaten pork.
If they have and are suffering from stomach pains, vomiting and diarrhoea then a diagnosis can be made. But, this depends upon the person seeking help in the first place.
Some people may decide to do nothing in the hope that these symptoms will ease by themselves after a couple of days. They may only seek help when they enter the second stage of the disease and experience chills, joint pains and itching.
A GP will look for signs of pain and tenderness in the joints and muscles as well as any past history of problems in these areas. He or she will also check to see if there any signs of bleeding under the fingernails or within the eyes. This will be followed by a series of laboratory tests, e.
Treating trichinosis Most cases of trichinosis resolve themselves. This means that they do not usually require any treatment unless the symptoms are severe or complications have developed.
Medication can be prescribed to destroy the roundworms within the digestive system or any inflammation within body tissues caused by these parasites.
Complications of trichinosis The vast majority of trichinosis cases clear up without any complications. However, there are a few situations in which serious conditions such as myocarditis or lung or nervous system problems have occurred which require medical treatment.
These complications may take 6 months to several years to clear.
Yersinia enterocolitica bacteria and pork food poisoning This type of food poisoning is caused by the yersinia enterocolitica bacteria which live inside raw pork.
It is not caused by the actual pork itself but by this strain of bacteria which also causes gastroenteritis.
This bacterium is able to access meats such as pork, beef and lamb due to poor food hygiene and handling. It also occurs if these meats are not stored correctly and at the right temperature. The problem with this form of bacteria is that it can survive even after being stored within a fridge.
But it can be destroyed through cooking so it is important to ensure that pork is well cooked. Ignore recipes which call for pork to be lightly cooked or undercooked. The main symptom is a severe form of diarrhoea which is accompanied by other symptoms such as stomach cramps, pain and fever.
Many of the symptoms are those caused by gastroenteritis and include nausea, vomiting and a loss of appetite. The diagnosis Your GP will examine you and will ask you about your medical history.
He or she may refer you for tests if your condition warrants this. The aim is to determine if your illness is food poisoning or gastroenteritis.Food poisoning (also known as food-borne illness) occurs when you eat or drink something that contains harmful germs (bacteria, viruses, or parasites).
Sometimes bacteria produce a toxin in food. It’s this toxin that causes the problem. Food poisoning may affect just one person or a whole group of.
Causes. When you have a food allergy, your immune system mistakenly identifies a specific food or a substance in food as something harmful. In respose, your immune system triggers cells to release an antibody known as immunoglobulin E (IgE) to neutralize the allergy-causing food or food .
Beef food poisoning. This type of food poisoning refers to beef and meat products in general, e.g. beef burgers. It also includes pates, sausages and sliced cooked meats.
In the United States, 1 in 3 or 76 million people contract food poisoning annually. That’s 1,, cases per week, , per day, 8, per hour, per minute, 2 per second. Food poisoning symptoms, onset of symptoms, and common food sources of 10 foodborne germs.
Typical symptoms include diarrhea,upset stomach, and vomiting. Food poisoning is a food borne disease. Ingestion of food that contains a toxin, chemical or infectious agent (like a bacterium, virus, parasite, or prion) may cause adverse symptoms in the body.
