Public Health Wales, Torfaen County Borough Council and Monmouthshire County Council are investigating an outbreak of cryptosporidium associated with Coleg Gwent’s farm in Usk.

Three people have tested positive for cryptosporidium and eight others are under investigation after a regular attendance at the farm.

Heather Lewis, Consultant in Health Protection for Public Health Wales, said “Cryptosporidium is a disease that is very common in young farm animals and can easily be passed to people who come into contact with those animals.

“It causes watery diarrhoea, stomach pain, nausea and vomiting, and can last for up to a month. Healthy people will usually make a full recovery.

“All the confirmed cases had direct contact with the lambs at the college farm. As part of our investigations, we are checking on all those whom we believe had contact with these animals and Coleg Gwent is co-operating fully with our investigations.

“Good hand washing after coming into contact with farm animals is of the utmost importance in preventing infection with cryptosporidium. There is no reason for anyone to avoid visiting petting farms as long as they ensure that anyone who has touched animals, thoroughly washes their hands with hot water and soap immediately afterwards.”

GPs in the Gwent area have been advised of the outbreak and asked to be alert to possible cases of diarrhoea or vomiting in people.

Anyone who is unwell with gastrointestinal symptoms is advised to contact their GP or NHS Direct Wales on 0845 46 47.

People who are unwell with vomiting or diarrhoea should not return to work or school for 48 hours after their symptoms have stopped.
