Starbucks Barista Exposes a New ‘Blending Powder’. Then They Warn What Allegedly Happens When It Becomes Airborne: ‘You Should Be Concerned’
Health hazard.
Starbucks just dropped a new “blending powder” into its drinks, and the internet is losing its mind over it. A viral TikTok video from creator @plaza849 shows a barista and her friend examining the powder while warning viewers about its potential risks. The clip has racked up over 8.3 million views and sparked a wave of concern about what’s really in those frozen blended drinks.
The video kicks off with the barista holding up the powder and saying, “Okay guys so this is me and Lori, we’re gonna be testing out the blending powder because, as you guys know, it’s toxic.” Lori doesn’t hold back either, quipping, “Bro, you’re gonna get cancer.” The pair then dive into the ingredients, zeroing in on silica – a compound that’s safe to eat but raises red flags when inhaled.
The video shows the fine powder becoming airborne as it’s scooped, which the baristas claim is causing coughing, sore throats, and headaches among employees. Starbucks introduced the blending powder in mid-July 2026 for its Blended Energy Refreshers, aiming to improve texture and consistency. The company insists the powder is FDA-approved and safe for consumption, containing food-grade silica rather than the more hazardous crystalline form.
That hasn’t stopped baristas and workers from sounding the alarm
The Starbucks Workers United union has been pushing for more transparency, arguing that the powder’s inhalation risks aren’t being addressed. According to Snopes, in a statement, they noted that Starbucks only shared brief guidance after the union demanded more information, and even then, the response didn’t tackle the inhalation concerns head-on. The powder’s ingredients list includes gum arabic, maltodextrin, xanthan gum, natural flavor, silica, and stevia extract.
While all of these are FDA-approved for consumption, the real debate centers on silica. Silica comes in two forms: crystalline and amorphous. Crystalline silica, found in sand and quartz, is a known lung irritant linked to serious conditions like silicosis and lung cancer. Amorphous silica is considered safer but isn’t entirely risk-free. The FDA requires food-grade silica to be synthetically manufactured to avoid contamination with the crystalline form, but that doesn’t eliminate all concerns.
Baristas have been posting videos showing clouds of the powder billowing into the air as they scoop it, which is where the problem lies. The fine dust can be inhaled, and while the FDA caps silica in food at 2% of the product’s weight, that doesn’t account for workplace exposure. The National Institute for Occupational Safety and Health (NIOSH) sets the recommended exposure limit for amorphous silica at 6 milligrams per cubic meter averaged over time.
Even if a barista scoops the powder multiple times a day, the exposure is likely below that limit – but that doesn’t mean it’s harmless. The body’s natural reaction to any foreign substance in the lungs is coughing, and baristas have reported exactly that, along with headaches and throat irritation.
The situation isn’t entirely unprecedented
Bakers, for example, deal with similar issues from inhaling flour dust, which can lead to a condition called baker’s asthma. The Massachusetts Department of Public Health estimates that 7% to 15% of bakers suffer from breathing problems due to their work environment. The difference here is that Starbucks’ blending powder is a newer addition, and baristas weren’t necessarily prepared for the potential risks.
Starbucks’ statement emphasizes that the powder is safe for consumption, but that’s not the issue. The concern is about the people handling it daily. The union has demanded more information and the right to bargain over the powder’s use, but so far, the response has been lacking. Meanwhile, customers are left wondering whether they should skip the blended drinks altogether.
Some commenters on the TikTok video are already calling for boycotts, while others are urging baristas to lawyer up, claiming they’re entitled to whistleblower protections if they’re fired for speaking out. The video’s caption lays out the ingredients and their purpose: the powder acts as an emulsifier and stabilizer, creating a smoother texture and preventing separation in blended drinks.
But the caption also highlights the health concerns, noting that baristas have reported throat irritation, coughing, and headaches. It states, “If you drink Starbucks you should be concerned about this.” One commenter, who claims to work in science, said: “Silica dust is EXTREMELY harmful to inhale. My staff are required to wear FULL RESPIRATORS when working with it. Please leave this job immediately, I’m so serious y’all are too young.”
The majority of responses leaned toward alarm
“Why do people like Starbucks again?” one user asked, while another declared, “STOP SUPPORTING STARBUCKS. Their coffee is trash + full of chemicals – plenty of small biz coffee spots to support!” A few even shared personal connections, like the commenter whose daughter, a Starbucks supervisor, confirmed the powder’s risks and admitted she avoids blended drinks now.
The debate isn’t just about whether the powder is safe to drink – it’s about whether Starbucks is doing enough to protect its employees. The company’s statement focuses on consumer safety, but baristas are the ones on the front lines, scooping the powder day in and day out. The union’s push for more information and workplace protections suggests this isn’t an issue that’s going away anytime soon.
