A rare species of “brain-eating amoeba” has caused an Iowa beach to temporarily close.

The beach at Ba Lua Lake in Taylor County is temporarily closed for swimming with immediate effect.

The Iowa Department of Health and Human Services announced the closure Thursday night.

The closure was caused by Naegleria fowleri, known as the “brain-eating amoeba.”

A Missouri resident was confirmed to have the infection after they were exposed while swimming in Lake Ba Fire.

The Centers for Disease Control and Prevention and the state are testing the water in the lake to confirm if there are brain-eating amoebas in the water. That check will take a few days.

This is the first case reported in Iowa, CDC data shows.

Amoebas that can cause life-threatening brain infections are extremely rare.

It can only happen if contaminated water gets into the swimmer’s nose, and cannot be passed from person to person.

In a statement, the state encourages people to take the following precautions to reduce the risk of infection by limiting the amount of water that reaches the nose:

  • Close your nose, use a nose clip or keep your head above the water when participating in water activities in warm freshwater.
  • Avoid water-related activities in warm freshwater during periods of high water temperatures.
  • Avoid deepening or stirring up sediment while engaging in water-related activities in warm and shallow freshwater areas.

Naegleria fowleri is rare and deadly

According to the CDC, of ​​the 154 known cases between 1962 and 2021, only four survived – a mortality rate of more than 97%.

The CDC says the majority of infections occur in freshwater — when temperatures hit triple digits.

Most cases occur in the southern US – but a recent study found the parasites appear in the Midwest more often.

The study says that could be the result of rising temperatures in the region.

Other lakes DNR does not recommend swimming:

The DNR has issued “no swimming” advice for these 11 beaches – including Big Creek in Polk County.

The problem in these lakes is not the brain-eating amoeba, most of which have higher levels of e coli or blue-green algae.

You can check the status of all State Park beaches at iowadnr.gov.
