Causes and symptoms of food poisoning

Food can become contaminated at any stage during its production, processing or cooking. Some of the main sources of contamination are described below.

Causes and symptoms of food poisoning

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.
