This recall involves Ascent™ and Venturist™ series 8-ounce and 20-ounce blending containers with blade date codes March 2018 (“03-18”) or earlier. If the blade base is marked on the bottom with a green or orange dot, the container has already been repaired. The Vitamix logo is printed on the blending container. The blade date code is laser-etched onto the top of the blade in the blade base. The products have a clear container and a black blade base and were sold separately.
