What does it all mean?
A Zoonoses is any disease that can be transferred from an animal to human that causes illness. All animals carry a range of micro-organisms, some of which can be transmitted to humans, where they may cause ill health – zoonoses. Some present a serious hazard and potentially cause severe disease, including Ecoli 0157.

What is E coli 0157?
E coli 0157 is an infectious illness which can be food or water borne. It is recognised initially by the symptoms. These can range from mild diarrhoea to severe bloody diarrhoea with abdominal pain. These symptoms can last for up to 2 weeks. In some extreme cases serious problems can occur including kidney failure. There are no tests on live animals to prove it is free from Ecoli 0157, and it does not make the animal ill. It should be assumed that all ruminants (sheep, cows, goats and deer) carry Ecoli 0157.

What is Cryptosporidium Parvum?

Cryptosporidiosis is a disease usually caused by the parasites Cryptosporidium hominis and C. parvum. It is most commonly seen in children aged between 1 and 5 years. People with weak immune systems are likely to be more seriously affected. The most common symptom is mild to severe watery diarrhoea.

The parasites are resistant to chlorine.

How are zoonoses transferred from animals to humans?
It is caused by bacteria entering the body through the mouth usually from unwashed hands and infected food or drink. Only very low numbers of the bacteria need to be consumed to cause illness.

Possible routes of the infection are:

  • eating undercooked meat, particularly minced meat, often in the form of burgers.
  • drinking raw (green top) milk or treated milk that has become contaminated after it has been pasteurised.
  • contact with streams, ponds and similar watercourses.
  • drinking unchlorinated water
  • infection from pets and farm animals.

If I catch E coli 0157 or another Zoonoses, will I need treatment?
There is no specific treatment for this particular illness and the most appropriate medication will depend upon the symptoms being suffered. Your doctor will be able to advise you what is most appropriate in your case. It is however, important to drink plenty of water to reduce the risk of dehydration.
