Mayor Jose Benitez Pantoja has warned that minerals in his town's drinking water is turning citizens gay.

Benitez warned against side-effects from the metal strontium, which he claimed had contaminated the water supply of the town of Huarmey, Peru.

“Unfortunately strontium reduces male hormones and suddenly we'll be as Tabalosos, where the percentages are increasing of homosexuality,” he said, referring to the town of Tabalosos, which is located in Peru's interior and provides the town's water. (Hear the audio by RRP.)

Benitez made his comments during a community event for a Water for All project in his province.

Last year, Bolivian President Evo Morales suggested eating chicken turns men gay.

“The chicken we eat is loaded with female hormones,” Morales, 52, said during an official appearance. “So when men eat those chickens, they have deviations in their being as men.”

Strontium, which is naturally occurring, can cause bone cancer, anemia and cardiovascular complications in unusually high doses, scientists have warned. However, no link to sexual orientation has ever been suggested before.
