Stanley is recalling approximately 2.6 million of its switchback and trigger action stainless steel travel mugs sold in the U.S. because of a potential burn hazard. The company said that the mug’s lid threads can shrink when exposed to heat and torque, causing the lid to detach during use, posing a burn hazard. Stanley has received 91 reports worldwide, including 16 in the U.S., of the recalled travel mugs’ lids detaching during use, resulting in 38 burn injuries worldwide, including two burn injuries in the U.S., with 11 consumers worldwide requiring medical attention. Stanley said the recall includes double-walled mugs sold in a variety of colors including white, black and green, in 12 oz., 16 oz.
