AUBURNDALE -- A Polk County lake is under a health alert, for blue-green algae.
The state health department says it tested Lake Whistler in Auburndale for toxins last Thursday. It's telling residents not to drink, swim or wade in the water, keep pets away, don't eat the fish, and don't jetski.
Blue-green algae are actually a type of bacteria that can make humans and animals sick. Moody Lake in Pasco County is under a similar alert.
