Red tide tests show lower concentrations in Palm Beach County

New test results for Karenia brevis in Palm Beach County show lower concentrations from the Palm Beach Inlet to Boca Raton.

The results, released Wednesday, were from samples taken Tuesday, according to the state’s red tide status map.

All of the samples showed low levels of the algae that shut down beaches last week and forced lifeguards to don masks to protect from breathing in the toxic cells that can cause coughing, watery eyes and wheezing.
