As Open Farm Sunday approaches on 8 June, Public Health Wales is reminding visitors to open farms to follow good hygiene practices when visiting farms. A further eight cases of cryptosporidium have been identified following visits to a Cowbridge farm in March and April 2025.
The fifth meeting of the multi-agency Outbreak Control Team was held on 24 May to respond to an outbreak of Cryptosporidium linked to visits to Cowbridge Farm Shop at Marlborough Grange Farm, Cross Ways, Cowbridge, CF71 7LJ.
The outbreak has resulted in 89 confirmed cases of Cryptosporidium.
The farm voluntarily stopped all public animal feeding activities on 29 April and have continued their ongoing support to the investigation. The Outbreak Control Team would like to thank the business for their cooperation and support as this outbreak begins to draw to a close.
Cryptosporidium is a parasite that can cause gastrointestinal illness, often associated with contact with animals, especially young farm animals such as calves and lambs. Public Health experts are warning those who have come into contact with infected cases to take extra care to avoid passing the infection onto others.
Su Mably, Consultant in Health Protection at Public Health Wales, said:
“We are continuing to work closely with our partners to investigate this outbreak and prevent any further spread of infection. Cryptosporidium usually clears up on its own, but it can cause more serious illness in young children and people with weaker immune systems.
“Cryptosporidium can also spread from person to person. If you develop symptoms after being in contact with someone who became ill following a visit to the farm, it’s important to get medical advice. Washing your hands properly at home, especially before eating or preparing food, is one of the best ways to stop the infection spreading.”
The main symptoms of cryptosporidium infection include:
The symptoms usually start between two and 10 days after exposure and can last for up to two weeks.
To help reduce the risk of infection, people visiting farms are reminded to follow these hygiene precautions:
Those who have been unwell with the symptoms above following a visit to a farm should:
Anyone who has symptoms and has visited the Cowbridge Farm Shop – especially those who took part in the calf or lamb feeding sessions – should contact their GP or call NHS 111 Wales and let them know that you have visited the site.
