Food poisoning and food borne illnesses

Most of us have suffered from eating something suspect, resulting in a trip to the toilet. But food poisoning is much more serious. Typically food poisoning takes a couple of days before the onset of symptoms and it can be more than a week before they end.

In most cases bacteria are responsible for causing food borne illnesses (such as campylobacter or salmonella), but not all. Other causes include:

  • Viruses - can cause gastroenteritis, such as Norovirus - also known as 'winter vomiting disease' - problematic in hospitals, nursing homes, schools and on cruise ships
  • Mycotoxins - can be carcinogenic - 'toxic mould' can affect some dried foods
  • Poisonous plants and fish - like scombrotoxic fish poisoning
  • Prions - an infectious agent resulting in nvCJD and BSE

Notification and investigation

Our Environmental Health team is formally notified by local doctors and hospitals when local people are found to be suffering from food poisoning.

When notifications are received the circumstances surrounding the illness are looked at to try to  identify the cause of the illness and give advice to prevent more people becoming ill.

We may contact anyone infected to try and establish what caused the illness. We also offer advice to prevent others becoming infected.  People who work in a food business and handle food must not work whilst they have symptoms of food poisoning and must also inform their manager.
