Faulty blending containers that allow blades to be exposed have cut the hands of nearly a dozen people, prompting the manufacturer to issue a recall in conjunction with the U.S. Consumer Product Safety Commission (CPSC) and Health Canada.

Blending container from Vitamix that’s under recall.

Made by Cleveland, OH-based Vitamix Corporation, the Ascent and Venturist Series 8oz and 20oz blending containers can separate from their blade’s base, exposing the blades. That leads to a laceration risk to consumers. As of this writing, 11 people have reported being cut by the exposed blades. “Consumers should immediately stop using the recalled blending containers and contact Vitamix for a free repair kit,” the CPSC said in a statement. “Vitamix is sending repair kits to consumers it can identify.”

About 105,000 units sold in the United States. An additional 5,300 were sold in Canada. Costco, Williams-Sonoma and www.vitamix.com sold the blending containers from April 2017 through July 2018.

According to the CPSC, the Ascent and Venturist series 8oz and 20oz blending containers have blade date codes of March 2018 (“03-18”) or earlier. Date codes are in the format MM-YY; for example, March 2018 is “03-18.” 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. They were sold separately and with Vitamix Venturist™ Model 1200 blenders.
