E.coli – know the risks and stay safe

Two outbreaks in Orkney in 2012 involved 10 confirmed of cases of infection involving the E. coli O157 bacteria. Extensive investigations were carried out but no common cause was found.

NHS Orkney and Orkney Islands Council are working together to raise awareness of the impact E. coli O157 can have.

What is E. coli O157?

Escherichia coli (E. coli 0157) is a relatively rare infection causing of illness ranging from mild diarrhoea to severe diarrhoea mixed with blood and associated with stomach cramps and pains. A small number of people develop more serious complications, such as kidney damage and problems with blood clotting, requiring urgent hospital treatment. Infection is more common in the summer and early autumn months.

How does infection occur?

E. coli bacteria are commonly found in the gut of animals and humans. E.coli are usually quite harmless, but some strains such as E. coli O157 can produce powerful toxins that cause illness. Only a very small number of the bacteria need to be swallowed by a vulnerable person in order to cause infection.

E. coli O157 is commonly carried in the gut of a variety of domestic, farm and wild animals and can be found in their faeces. It can be spread by swallowing the bacteria during or after direct contact with infected animal faeces, or by indirect contact – for example with soiled work clothes, or during picnics or barbeques in the countryside, in gardens or on the beach. It can also be spread following the consumption of contaminated water.

E. coli O157 infection can also be linked to eating contaminated meat or dairy products. The infection can then be spread from person to person following contact with contaminated handles, food preparation surfaces and even shared towels.

Back to Frequently Asked Questions

How do I stop it spreading?

As E. coli O157 can spread very easily from person to person and as just a few germs can cause infection, good hygiene is essential.

People with E. coli O157 infection should not prepare food for other people.

After using the toilet, wash hands, rinse under warm running water and dry them thoroughly.

If you have the infection, use a separate towel, or kitchen roll, from the rest of the household.

Keep the bathroom and toilet clean, paying particular attention to cleaning the toilet seat, flush handles, door handles, washbasins and taps.

The flush and door handle should be disinfected each time the toilet is used.

Young children with E. coli O157 need to be carefully supervised when using the toilet. Nappies must be wrapped in plastic bag prior to disposal.

You should inform your place of work or in the case of children, their child minder, nursery, play group or school.

How important is hand washing?

Effective and frequent hand washing is one of the single most important things we can do to help to reduce the spread of infections and prevent ill health. For example, good hand hygiene in children will help to prevent the spread of common communicable infections such as colds and tummy bugs.

A short film is available, produced with children in mind, that shows how it’s done and is available on the Health Protection Scotland website by following the link in the 'Related Sites' section of this page.

Where can I get more advice?

Your GP will be able to advise you and your family. You may be asked by your doctor to provide a faecal (stool) sample.

Advice can be provided by the Environmental Health Team at Orkney Islands Council.

As a new service, we can provide home advisory visits. These provide an opportunity to talk over any questions you might have about effective cleaning, good hand hygiene, and preparing and cooking food safely – all the things you need to do to keep you and your family safe and well.

For further information and to arrange a visit, phone the Environmental Health Team on 01856873535.

A wealth of information is also provided on the Health Protection Scotland website available from the 'Related Sites' section of this page.

How do I provide a faecal of stool sample?

Check that your name and the date of birth is on the specimen pot provided by your GP or health centre. If missing add those details to the label on the tube and then write the date of your sample.

Collect the stool specimen in a container (such as an old margarine or ice-cream tub) which has been well washed. Alternatively, you may have a child’s potty.

When you have the stool specimen, use the scoop inside the tube:

When you have finished with the collection container (not the specimen tube):
