Starbucks pulls airborne blending powder after barista health complaints

The Powder Controversy
In mid-July, Starbucks introduced a new blending powder for its Blended Refreshers. Baristas reported that scooping the powder generated fine dust that caused headaches, coughing, sore throats, hives and asthma attacks. After a surge of complaints, the company removed the ingredient from all U.S. stores, noting that the change coincided with a regular seasonal menu transition.
Background & Context
Starbucks Workers United, representing more than 12,000 baristas at over 700 unionized stores in 45 states, has been bargaining for its first contract since its formation in 2021. Health-and-safety protections, including advance notice of new ingredients, are a central demand alongside higher wages, consistent scheduling and staffing guarantees.
Timeline
- July 14 – Starbucks launches the blended-drink line and instructs baristas to add the powder as a binding agent.
- July 27 – The company posts a statement that the powder contains a small amount of food-grade silica, an FDA-approved food ingredient, and is “safe for use in food.”
- August 15-16 – Walkouts occur in California, Missouri, Tennessee and Pennsylvania, with workers citing the powder’s airborne dust.
- August 25 – Starbucks Workers United announces a boycott of the chain to pressure a contract.
- August 26 – The AFL-CIO and the Chicago Teachers Union join the boycott.
Data & Statistics
- Union reach: >12,000 baristas, >700 stores, 45 states.
- Survey response: Nearly 600 baristas reported illness after the powder’s launch.
- Unfair-labor-practice charges: 550 unresolved cases, the largest tally in U.S. history.
- Staffing demand: At least three workers on the floor at all times.
- Wage request: $17 hour starting pay with 4 % annual raises.
Official Statements & Responses
The July 27 statement emphasized the ingredient’s FDA-approved silica content. Starbucks Workers United has demanded permanent removal of the powder, higher staffing levels, and consultation with baristas before introducing new ingredients. The union also noted that money spent on the powder could have been allocated to contract negotiations and staffing.
Criticism & Opposition
Union organizer Jasmine Leli argued that safety training and labeling were inadequate, noting that internal instructions to “pour slowly” conflicted with the brand’s speed-driven culture. Baristas said the requirement to prepare drinks in under four minutes left no time to mitigate dust exposure. Additional grievances include chronic understaffing, reduced hours that jeopardize benefits, and pressure to work faster despite health risks.
Verbatim Quotes
- “It was multiple days until I connected the dots that it maybe had something to do with the powder,” — Destiny Valencia
- “We know our collective action prompted the company to direct stores to remove the powder, but the risk of using this product remains, and we won’t stop calling for its permanent removal from every store,” — Jasmine Leli
- “If you have asthma and if you are in fact sensitized to this material … then very low doses are going to cause you significant respiratory problems,” — Dr. Peter Orris
What’s Next
The boycott launched on August 25 aims to sustain pressure until Starbucks signs a contract that addresses staffing, wages and health-and-safety standards. The AFL-CIO and Chicago Teachers Union have pledged support, and further walkouts are possible if negotiations stall.
Conflicting Reports & Gaps
Starbucks maintains that the powder’s silica content is safe for consumption, while Dr. Peter Orris cautioned that inhalation of food-grade amorphous silica, gum arabic and xanthan gum can trigger respiratory irritation, especially for asthmatic workers. The company has not provided independent air-quality testing results, leaving the extent of occupational exposure unverified.
