The UK Health Security Agency (UKHSA) has reported a concerning surge in cryptosporidiosis cases, a diarrhoea illness caused by a microscopic parasite. The number of confirmed cases has doubled, reaching 46, with over 100 additional people experiencing similar symptoms in the Brixham area.

Residents and visitors in the south Devon town have also reported diarrhoea and vomiting, prompting investigations. Social media posts reveal that hundreds of locals have felt unwell over the past two weeks.

The source of contamination appears to be a damaged air valve on a pipe within a field containing cattle. Traces of the parasite were detected in the local water network. Laura Flowerdew, South West Water’s chief customer officer, suggests that cattle manure may be responsible for the contamination.

The affected area includes Alston and the Hillhead area of Brixham, where SWW has issued a “boil water notice”. Water tests revealed small traces of cryptosporidium, which causes sickness and diarrhoea.

Flowerdew emphasises the need to verify that the damaged air valve is the sole source of contamination. While the valve is near the Hillhead reservoir, it is not directly connected to the reservoir itself.

Approximately 40,000 people are impacted by the boil warning. SWW has increased compensation for affected customers to £115. Bottled water is being delivered to vulnerable individuals and local businesses, including schools.
