Mexican health authorities say two beaches in Acapulco are severely contaminated and one in Zihuatanejo registered pollution slightly above permitted levels.
The Federal Commission for Protection against Health Risks says both Suave and Hornos beaches in Acapulco register over 3,000 units of fecal Enterococcus bacteria per 100 milliliters of tested water. That is well above the accepted 200 units.
The commission said Zihuatanejo's Principal Beach has bacteria levels of 233 units, slightly above accepted levels. The Zihuatanejo beach is among the most crowded at the resort spot favored by both Mexican and U.S. tourists.
Gastrointestinal illnesses as well as eye, ear and skin infections could result from exposure to the bacteria.
