Public health officials have confirmed 47 cases of cryptosporidium infection linked to recent visits to Cowbridge Farm Shop at Marlborough Grange Farm, Cross Ways, Cowbridge.

A second meeting of the multi-agency Outbreak Control Team was held on 2 May to assess the situation, with officials warning that case numbers may continue to rise due to the infection’s incubation period, which can range from two to ten days.

In response to the outbreak, the farm has voluntarily suspended all public animal feeding activities and is cooperating fully with the investigation, according to Public Health Wales.

Cryptosporidium is a microscopic parasite that causes gastrointestinal illness, and is often associated with contact with 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.”

Symptoms of cryptosporidium infection include:

Watery diarrhoea
Stomach cramps or pain
Nausea or vomiting
Mild fever
Loss of appetite and weight loss

Although symptoms typically resolve within two weeks, health authorities stress the importance of seeking medical advice, especially for vulnerable groups.

Visitors to farms are advised to follow these hygiene precautions:

Wash hands thoroughly with soap and warm water after touching animals or farm equipment, and always before eating or drinking. Alcohol-based gels are not effective.
Avoid eating or drinking while walking around the farm or handling animals.
Refrain from holding, cuddling, or kissing animals, which significantly increases infection risk.
Clean footwear and wash hands after leaving the farm.
Closely supervise children to ensure they wash their hands properly and avoid close animal contact.
Pregnant women should take extra care and avoid newborn lambs during lambing season.

Public Health Wales and partner agencies continue to monitor the outbreak closely and will provide further updates as necessary.
