Utah Woman Says McDonald’s Grinch Fries Triggered an Unexpected Reaction: ‘Was Seriously Horrific’

In Utah, a festive fast-food experiment quickly turned unsettling, leaving many people uneasy about what they’re putting on their plates this holiday season. As major brands roll out cheerful, limited-time menu items meant to spark joy and nostalgia, one local McDonald’s customer and her co-workers’ experience has cast a shadow over the excitement.

It began as just another seasonal promotion riding the wave of holiday hype. But the aftermath, shared publicly, struck a nerve and spread rapidly across social media, prompting concern, jokes, and skepticism all at once.

McDonald’s recently teamed up with Dr. Seuss Enterprises to release its Grinch-themed meal, launching in early December. The centerpiece of the offering is a bold twist on fries. Dill Pickle–flavored “Grinch Salt” McShaker Fries, paired with either a Big Mac or Chicken McNuggets and a drink. Customers are encouraged to pour the seasoning into the fry bag and shake it themselves, coating the fries in the tangy green-themed blend.

Festive Meal Takes a Dark Turn For Utah Woman and Co-Workers

For a Utah-based McDonald’s Customer named Ella Ashcraft, curiosity got the better of caution. Along with two coworkers, she decided to try the new fries. What followed was far from festive. Within hours, she says all three of them became violently ill.

Ashcraft later shared an image on TikTok that told the story without words. A bathroom turned into a makeshift recovery station, stocked with crackers, soda, wipes, towels, and sickness bags. According to her account, the physical toll was severe and sudden, leaving her drained and miserable in a matter of hours.

The post quickly exploded, pulling in millions of views in just days. While many viewers expressed concern, others leaned into dark humor. Some joked about the rapid weight loss she mentioned, sarcastically referring to the fries as a “budget Ozempic” and asking how many meals it would take to drop a few pounds before vacation season.

Foodborne illness can occur when food is mishandled, improperly stored, or contaminated, leading to symptoms that range from nausea and stomach cramps to vomiting, diarrhea, and fever. These symptoms can appear quickly and vary in intensity. With so many people already dealing with seasonal illnesses, distinguishing food poisoning from a virus isn’t always clear-cut.

Alarm, Jokes, and Caution

That uncertainty is what’s fueling suspicion. When new menu items roll out nationwide, especially ones involving unusual flavor combinations, consumers expect safety to be a given. This Utah woman’s experience reminds us that not every holiday treat comes without risk.

The viral post has fueled jokes about “accidental weight loss” and people half-seriously eyeing the Grinch fries as some kind of budget cleanse. The situation itself is far from funny. Severe illness that leaves someone bedridden for hours is alarming, no matter the source.

“BEWARE OF THE GRINCH MEAL,” one follower writes.

“Grinch fries shrink your stomach, not heart,” another jokes.

“It was seriously horrific,” the OP responds.

“Call me influenced,” one more adds.

At the same time, it’s important to note that there is no confirmed evidence that the Grinch fries directly caused the reaction. With flu cases and aggressive stomach bugs spreading rapidly across the country. It remains entirely possible that timing, not seasoning, played a major role.

Still, the experience serves as a reminder that trendy, limited-time foods aren’t always harmless. Especially when multiple people report sudden illness after eating the same item, it naturally raises concern. Until more is known, caution may be the smartest choice. Especially when a holiday treat leaves more questions than cheer.
