Update on Cryptosporidium cases linked to Cowbridge farm visits

Published: 2 May 2025 

Statement

A second meeting of the multi-agency Outbreak Control Team was held today (2 May) to assess the ongoing outbreak of Cryptosporidium linked to visits to Cowbridge Farm Shop, Marlborough Grange Farm, Cross Ways, Cowbridge CF71 7LJ.

The number of confirmed cases has now reached 47. Due to the incubation period of the infection, we expect that this number may increase in the coming weeks. 

The Outbreak Control Team continues to work closely with the premises to investigate this outbreak. The farm has voluntarily ceased all public animal feeding activities and is cooperating with the investigation.  

Cryptosporidium is a parasite that can cause gastrointestinal illness, often associated with contact with animals, especially young farm animals such as calves and lambs. 

Su Mably, Consultant in Health protection for Public Health Wales said:

“We are continuing to investigate this outbreak with our partners. While the infection is usually mild and self-limiting, it can be more serious in young children or people with weakened immune systems. We urge anyone who visited the farm and is feeling unwell to contact their GP or NHS 111. Practising good hygiene is the best way to protect yourself and others.” 

The main symptoms of cryptosporidium infection include: 

  • Watery diarrhoea 
  • Stomach pains or cramps 
  • Nausea or vomiting 
  • Mild fever 
  • Loss of appetite 
  • Weight loss

Symptoms usually start two to 10 days after contact with the parasite 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: 

  • Always wash your hands thoroughly with soap and warm water after touching animals, after touching boots or clothing, and before eating or drinking. Alcohol based hand gels do not provide sufficient cleaning. Always use soap and warm water.  
  • Do not eat or drink while touching animals or walking around the farm. 
  • Avoid close contact with animals – including holding, cuddling or kissing – as this significantly increases the risk of illness. 
  • Remove and clean footwear and wash hands after leaving the farm. 
  • Supervise children closely to ensure they wash their hands properly and avoid close contact with the animals. 
  • Pregnant women should take particular care and avoid contact with newborn lambs during lambing season. 

 
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 and let them know that you have visited the site.
