Officials at the Sedgwick County Zoo in Wichita are getting rid of blue sno-cones after a mix-up involving commercial degreaser.

Four people became ill Thursday when a zoo employee poured a degreasing agent into the sno-cone machine instead of flavored syrup.

The two bottles are the same size, shape and color and accidentally got stocked next to each other. A zoo spokeswoman said the employee didn't read the labels and apologized to families who got sick.
