Spain's 'Brown Challenge' Forces Pool Closures Across the Country 2026

The 'Brown Challenge' in Spain has escalated from a crude prank to a public health crisis, forcing hundreds of swimming pools to close temporarily. This disturbing trend involves individuals defecating in pools, often as part of a social media challenge, and it's creating serious risks for swimmers, especially children.

What Is the 'Brown Challenge'?

The 'Brown Challenge' is a viral phenomenon where people intentionally defecate in swimming pools, sometimes recording the act for online clout. What began as a disgusting joke has now become a recurrent problem across Spain, with incidents reported in numerous municipalities.

In 2025 alone, over 300 municipal pools across the country were affected, according to data collected by local councils and public health services. The challenge often occurs at the end of the day when surveillance is lower, making it difficult to identify the culprits.

Recent Incidents and Pool Closures

The impact has been widespread. In Valencia, a dozen municipalities—including Silla, Oliva, Chiva, Requena, and Picassent—have had to close pools temporarily. In Tàrrega (Lleida), municipal pools closed three times in a single week in August 2025 after human feces were found in the main pool.

Cáceres has also seen similar closures. Most recently, in Barro (Asturias), local authorities appealed for public cooperation: "We ask for the collaboration of all users. If anyone saw anything or has information that could help identify the person or persons responsible, we appreciate you reporting it to the Council or pool staff."

These closures not only disrupt summer recreation but also impose financial burdens on municipalities and pose health risks, particularly for children and the elderly.

Health Risks and Public Response

Fecal contamination in pools can spread pathogens like E. coli, Cryptosporidium, and norovirus, leading to gastrointestinal illnesses. Children, pregnant women, and immunocompromised individuals are especially vulnerable.

In response, many towns have increased surveillance, tightened entry protocols, and launched public awareness campaigns. However, catching perpetrators is challenging due to the clandestine nature of the act. The background to this story is set out in Medicaid Cuts Trigger Maternity Ward Closures Across the US.
