In the Salzburg region, a sudden outbreak of gastrointestinal symptoms occurred after a heavy storm. About a dozen children and adults experienced diarrhoea and vomiting shortly after swimming in the Almkanal, a popular recreational stream.
The Salzburg Health Authority suspects that the intense rainfall washed manure from nearby farmland into the canal, contaminating the water. The temporary pollution affected an area frequently used by families and leisure visitors.
Salzburg Emergency Services provided on‑site first aid and transported those needing further care to nearby hospitals. No severe cases have been reported; most individuals were discharged after brief observation. The health authority has closed the bathing area and posted warning signs to prevent further exposure.
The Salzburg Water Management Office is cooperating with the provincial agricultural authority to determine the exact cause. Water samples are being tested for bacterial indicators such as E. coli and enterococci. Preliminary results are expected within a few days, after which preventive measures may be considered.
