The new challenge that took Spain by surprise is... shitting in pools. Seriously. Health chiefs have slammed the new viral fecal challenge sweeping Spain. The crap challenge urges young people to poo in water parks and swimming pools as a new dare. At least one big aqua park has had to close because of the health risk and it is feared others might face the same dangers.

Staff at the huge Segóbriga Park water park in Valencia said they were "absolutely disgusted" to find human poo in the water and say it was a deliberate act, not an accident. According to El Periódico Mediterráneo, Valencia is the worst hit region so far but the challenge is quickly going viral across Spain and has spread to holiday beaches, as well as pools. The sick challenge is being called “Hacer Caca” or in English "Make a Poop" and is aimed at young teenagers from 12 to 16 via the social networks and internet. They are urged to film or photograph themselves doing the deed and to post videos online.

It has been slammed as "absurd" and "a dirty trick" and costs thousands of pounds to squirt out because pools have to be closed and drained due to the health risk. Segóbriga Park, near Valencia, has been forced to close twice in just one week after human poo was found in the water and the facilities had to be disinfected. The local council said it was furious about the situation and called on users to respect the water kingdom to "maintain the good tourist image of Segorbe tourism." Other towns in the region including Catarroja, Massanassa and Tavernes Blanques have suffered similar attacks of the bowel. In Catarroja, the town's pool had to be closed for 24 hours because someone defecated in the water.

The local Mayor said it had been dung as a deliberate act of hooliganism. In Massanassa, also in Valencia, the outdoor water park pool was put out of action on four consecutive days after a poop was found floating in the water. And in Tavernes Blanques, following similar incidents, the local council announced it would be increasing security measures and was looking at installing an instant detection system which would give an immediate alert to anyone defecating, probably through the use of a reactive dye. Announcing the reopening of its water park, Segorbe council said: "Segóbriga Park has opened its doors again after the closure for disinfection work. "We apologise for any inconvenience this may have caused and we once again call on the citizenship of bathers.

"We appeal for respect so that these types of actions do not harm local people and the tourists who visit us and to ensure the good image of Segorbe tourism." In Murcia, a municipal swimming pool also had to be closed twice when poo was found in the water. The local council installed CCTV and caught a group of teenagers sneaking in and pooping on purpose. Health chiefs say the new challenge is potentially very dangerous as human poo can generate bacteria and be very harmful to health. The biggest question is- HOW STUPID CAN YOU BE?!?
