This week’s recalls and consumer warnings at America’s largest retailer include chainsaws with an off switch that doesn’t work and incorrectly labeled Ritz cracker sandwiches.

Boxes of Ritz Peanut Butter Cracker Sandwiches have been recalled from retail stores nationwide, including Walmart stores in 50 states and Puerto Rico and Target stores. The problem described in Mondelēz Global’s recall notice sounds like a simple oopsy — individual six-packs of Peanut Butter Cracker Sandwiches in wrapping for Cheese Cracker Sandwiches — but can have horrible consequences.
