Health officials have confirmed a serious outbreak of a bacterial infection connected to a major music event held in Wales this summer.
Outbreak Declared at Welsh Festival
Public Health Wales has officially declared an outbreak after multiple people who attended The Big Tribute Festival reported falling ill. The festival took place in Aberystwyth between August 22 and 24, 2025.
Several guests contracted a specific strain known as O26 Shiga toxin-producing E. coli (STEC). This particular bacterial infection can cause severe symptoms and, in some instances, may become life-threatening.
Urgent Investigation Underway
A multi-agency response is now in full swing to manage the situation. Public Health Wales is leading the investigation in collaboration with Ceredigion County Council and the Hywel Dda University Health Board.
Their primary focus is to identify the origin of the contamination and prevent further spread of the infection. The investigation is standard procedure for such public health incidents.
Understanding the Health Risks
Shiga toxin-producing E. coli is a concerning bacteria known for causing severe gastrointestinal distress. Symptoms often include intense stomach cramps and diarrhoea, which may be bloody.
While many healthy adults recover within a week, the infection can be far more dangerous for vulnerable groups, including young children and the elderly, potentially leading to serious complications.
Authorities are urging anyone who attended the festival and experienced significant symptoms to seek medical advice and mention their potential exposure to this outbreak.
