In Latvia, health officials issued warnings regarding the safety of public drinking water sources and microbiological contamination. Health Inspection director Normunds Kadiķis noted that visible water clarity does not guarantee safety and that many sources lack continuous state monitoring. 

Specifically, water samples taken in late July 2026 at the official swimming area of Saldus Lake revealed elevated Escherichia coli levels. Authorities advised against swimming at the site, particularly for vulnerable groups such as children, the elderly, and those with weakened immune systems, while noting that other official swimming sites in the country met quality standards.

## Claims

- E. coli should remain part of standard monitoring in inland waters. (corroborated by 2 sources)
- Approximately 2.1 percent of swimmers reported gastrointestinal symptoms one week after testing. (corroborated by 2 sources)
- Skin issues such as rashes or itching occurred twice as frequently in swimmers compared to those staying on the shore. (corroborated by 2 sources)
- There is a direct correlation between illnesses and E. coli levels in water. (corroborated by 2 sources)
- Skin problems may be caused by algae or parasites rather than fecal bacteria. (corroborated by 2 sources)

## Timeline

### 2026-08-28: E. coli levels in rivers and lakes linked to health risks

A study of 2,400 people in Hungary shows that wild swimming increases risks of gastrointestinal illness and skin issues, challenging current WHO water monitoring guidelines.
