Woman says she took one sip of her McDonald’s iced coffee and immediately knew something was wrong: “Wasn’t anything that should EVER be in a drink”

One sip was enough for Lana Teasley to question what was in her McDonald’s iced vanilla coffee. She said she nearly vomited, then kept the lid because a substance remained on it that she wanted tested.

In a public Facebook post, Teasley described ordering her usual drink on a Friday morning at the McDonald’s at Opdyke and University roads. “It wasn’t coffee, cream, sugar, or anything that should EVER be in a McDonald’s drink,” she wrote.

She offered to hand over the lid and said her family would avoid the chain until the incident was investigated. While Teasley questioned whether someone had tampered with her coffee, her post did not establish what the substance was or how it got there.

She says this was nothing like her usual order

Teasley wrote that she visits different McDonald’s restaurants regularly and had never had an experience like this. She described the stop as one of her worst restaurant visits and pointed readers to photographs of the cup and lid.

“The taste was so wrong, so off, and so disturbing that I knew instantly something was not right,” she wrote. As for what remained on the lid, she insisted it was “NOT whipped cream.”

She said she had held onto it and was willing to give it to McDonald’s. “If McDonald’s wants it, they can have it — I will hand it over for testing,” she wrote.

The mother of two said she did not have time to return and argue with employees. Instead, she posted the warning, explaining that the experience had left her questioning a restaurant she previously trusted.

She wrote that customers should never have to wonder whether someone tampered with their drink. Her post did not describe seeing anyone alter the drink or say whether she had contacted health officials.

McDonald’s does serve cold foam, but that leaves her question unanswered

Whipped cream is not the only topping on McDonald’s drink menu. The chain’s Dirty Soda line, available at participating restaurants, combines a soda of choice with vanilla flavor and chilled cold foam.

Despite the menu option, that does not mean cold foam ended up in Teasley’s coffee. What was on the lid, and why the drink tasted wrong to her, remain unanswered questions.

Customers with concerns about a McDonald’s order can use the company’s restaurant feedback form, which lets them identify the location using their receipt or the restaurant locator. Customers can also report suspected food-safety problems to the health department serving the restaurant’s area, according to USDA guidance.

Teasley said she saved the lid so McDonald’s could test it, but her post did not say whether anyone had agreed to take it. She also did not share test results or say a doctor had diagnosed her with an illness after drinking the coffee.

It is unclear whether she spoke with a manager or gave restaurant staff a chance to look at the cup and lid. For now, her account describes a drink that tasted wrong to her and something on the lid she could not identify. We do not yet know what caused either problem.

The Mary Sue contacted Teasley and McDonald’s for comment. Neither had responded by publication, and we will update this report if we hear back.
