Food poisoning

Our Food Safety team plays a key role in reducing the spread of infectious disease by:

  • inspecting food premises to make sure food is handled safely and bacterial growth is kept to a minimum
  • taking samples of food for analysis to ensure that it is safe to eat
  • visiting people suffering with food poisoning in an attempt to identify the source and giving advice on preventing its spread.

The risk of food poisoning can be reduced by following good hygiene practices.

  • A rare infection caused by listeria bacteria - found in rotting vegetable matter, sewage, soil, water, farm animals, domestic pets and humans.
  • Most cases are caused by the consumption of infected food.
  • Unlike other food poisoning bacteria, listeria is a potential hazard in chilled food since it can grow at refrigeration temperatures below 5°C. The foods that cause most outbreaks are prepared salads, ready meals, and ripened soft cheeses.
