Starbucks blending powder triggers barista health complaints
Starbucks employees have warned customers that a newly introduced blending powder used in frozen drinks may be toxic. The powder, added to Blended Energy Refreshers in July, contains gum arabic, maltodextrin, xanthan gum, silica (silicon dioxide), natural flavor and stevia extract, serving as an emulsifier and stabilizer. Baristas across U.S. and U.K. stores report coughing, sore throats, chest irritation and headaches after the fine powder becomes airborne during preparation. Employees posted videos on social media describing the symptoms and urging people to stop using the powder, while the union Starbucks Workers United said it has received multiple reports of respiratory irritation. The controversy has drawn attention to the silica component, which is commonly associated with industrial dust and can be hazardous when inhaled.
