WAIKIKI (HawaiiNewsNow) - The Department of Health is alerting the public of elevated bacteria levels at two Oahu shorelines.
The first alert is for those heading to Pokai Bay.
On Wednesday, the DOH said enterococci levels greatly exceeded the normal threshold. Regular testing found that enterococci levels were 2005 per 100 mL.
The normal level is 130 per 100 mL.
The second alert came a day earlier for beachgoers in Waikiki.
Waters near the Moana Surfrider had elevated levels of the same bacteria, registering at 238 per 100 mL.
High levels of bacteria are usually caused by runoff from heavy rains and can carry harmful parasites that can cause people to get sick.
Health complications can include nausea, vomiting, stomachache, diarrhea, headache or fever. Ear, eye, nose and throat infections may also occur.
Children, the elderly, and people with weakened immune systems are most at-risk to develop symptoms.
The DOH will continue monitoring water conditions, especially in light of heavy recent heavy rain.
