Key Summary
At the height of the tourist season in late August, routine water quality tests conducted by Spanish health authorities at numerous coastal bathing spots have detected levels of Escherichia coli (E. coli) and Enterococcus bacteria exceeding safety standards. These two bacteria are key indicators of fecal contamination in water, and high concentrations increase the risk of gastrointestinal and skin infections for swimmers. In response, several local governments have taken emergency measures to close the affected beaches.
Andalusia: Five Beaches Affected in the Province of Cádiz
The province of Cádiz in the Andalusia region is one of the key areas affected by the water quality issue. Following the latest round of testing, health authorities have ordered a temporary swimming ban at the following five beaches:
- El Puerto de Santa María: Aculadero-Puerto Sherry and Fuentebravía beaches.
- Chipiona: Micaela beach.
- Puerto Real: La Cachucha beach.
- Rota: Punta Candor beach.
Test results showed that Aculadero-Puerto Sherry, La Cachucha, and Micaela beaches all had excessive levels of both E. coli and Enterococcus. Fuentebravía beach primarily exceeded the limit for Enterococcus, while Punta Candor beach exceeded the limit for E. coli. Local city councils have, as required, installed warning signs prohibiting swimming in conspicuous locations on the beaches.
Galicia and the Canary Islands: Frequent Contamination Incidents
In addition to Andalusia, other regions have experienced similar problems. In Galicia, swimming was discouraged at A Calzoa beach in the city of Vigo on August 27 due to high E. coli levels. Previously, water quality anomalies were also reported in other areas of the region, such as Samil, A Punta, and the Cíes Islands. Local health officials suggest that recent heavy rainfall may have caused land-based pollutants and untreated sewage to be washed into the sea.
Meanwhile, in the Canary Islands, the famous Playa Jardín in Tenerife was once again closed to swimmers due to water quality issues. A water sample test on August 10 showed E. coli levels as high as 470 colony-forming units (CFU) per 100 ml, and a follow-up test the next day saw this number surge to 850 CFU, far exceeding the legal safety limit.
Official Response and Health Risk Advisory
In response to these incidents, health authorities in various regions are implementing unified measures. New water samples will be collected and analyzed from all closed beaches. The swimming bans will only be lifted after consecutive test results confirm that the water quality has returned to safe standards. Andalusia’s health monitoring program will continue to survey all 304 coastal bathing areas in the region from June to the end of September.
Experts remind the public that excessive bacteria in the water is not always accompanied by visible pollution, but its presence indicates a risk of fecal contamination. The bans issued by authorities are based on the precautionary principle, aimed at protecting public health. Tourists and residents at the beach should pay close attention to flags and warning signs, strictly adhering to “No Swimming” rules. This is especially important for children, the elderly, and individuals with weakened immune systems, who should avoid any activity in waters of uncertain quality.
