For someone who built a career eating some of the world’s most extreme foods, even Andrew Zimmern didn’t see this coming.
The longtime television host and culinary adventurer — famous for trying everything from fermented shark in Iceland to still-beating snake hearts in Vietnam — says he developed a painful, lingering condition after filming in northern Africa: burning mouth syndrome.
Sometimes referred to as glossodynia, burning mouth syndrome causes a chronic burning, tingling, or scalding sensation on the tongue, lips, or throughout the mouth, often with no obvious cause. Zimmern shared his experience during a Reddit “Ask Me Anything,” revealing that the condition traces back to a single meal nearly two decades ago.
“In 2005, I contracted a virus from eating tainted cumin in Northern Africa,” Zimmern wrote. “Occasionally once a year I have a flare-up of a rare disease called burning mouth syndrome. I pass it off as a simple casualty of war.”
In a later interview with ABC, Zimmern said the condition still follows him today. He carries medication in case of flare-ups and described the illness as viral in nature. While early reports suggested the condition was extremely rare, medical estimates now indicate that roughly 1 to 3 percent of the global population experiences burning mouth syndrome to some degree — though its exact causes remain unclear.
At first, Zimmern assumed he’d simply pushed his taste buds too far, an understandable conclusion for someone whose job involved eating unusual and often extreme foods around the world. But when the burning sensation didn’t fade after he returned home, doctors eventually diagnosed him with the neuropathic condition.
So was cumin really to blame?
Food safety experts say it’s not impossible. Cumin is one of the most widely traded spices in the world and is often sold ground, which makes it vulnerable to contamination. In many regions, especially across North Africa, the Middle East, and South Asia, spices are commonly stored in open sacks at outdoor markets, where they can be exposed to bacteria, dust, or other contaminants. In fact, one of the largest U.S. spice recalls in recent history involved cumin contaminated with peanut protein, highlighting how frequently spices can become adulterated.
Despite the ordeal, Zimmern hasn’t sworn off bold flavors or adventurous eating. He still travels internationally, still uses cumin in his cooking, and continues to explore wild foods — though these days he keeps a medicated rinse close by, just in case..
