In Wales this week, the cryptosporidium outbreak associated with Cowbridge Farm Shop at Marlborough Grange Farm, Cross Ways, Cowbridge, has officially been declared over by the multi-agency Outbreak Control Team (OCT).
A total of 89 confirmed cases were linked to the outbreak. No new cases have been identified since the last OCT meeting was held on 28 May 2025, the outbreak is now considered closed.
Although, the outbreak has ended, Public Health Wales continues to stress the importance of practicing good hygiene – including thorough handwashing with soap and water – especially after contact with animals or the natural environment.
The main symptoms of cryptosporidium infection include:
Watery diarrhea
Stomach pains or cramps
Nausea or vomiting
Mild fever
Loss of appetite
Weight loss
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:
Avoid close contact with animals – including holding, cuddling or kissing animals – this significantly increases the risk of illness.
Always wash your hands thoroughly with soap and warm water after touching animals, footwear, clothing, bikes, scooters, prams etc. before eating or drinking. Alcohol based hand gels do not provide sufficient cleaning.
The physical action of washing with soap and water is the most reliable way to remove the parasite from the skin.
Supervise children closely to ensure they wash their hands properly and to avoid close contact, especially cuddling or kissing the animals.
Do not eat or drink while touching animals or walking around the farm.
Remove and clean footwear and wash hands after leaving the farm.
Pregnant women should take particular care to avoid contact with newborn lambs during lambing season.
