Costco accused of selling protein powder contaminated with lead, arsenic

Costco faces a class-action lawsuit alleging the sale of Orgain Organic Protein Powder containing undisclosed lead, cadmium, and arsenic. Plaintiffs claim the product's packaging and marketing, including USDA Organic certification and 'clean nutrition' language, misled consumers about its safety, despite a Consumer Reports test finding lead levels exceeding concerns. The FDA does not pre-test supplements, leaving consumers reliant on retailers' safety claims.
