Yucatán health authorities detected the brain-eating amoeba Naegleria fowleri in six artificial lakes in Mérida, Mexico, and suspended all water contact pending sanitation. The finding is confirmed by official testing, but the source and extent of contamination remain unclear. This poses a public health risk, though no infections have been reported yet.
