Does McDonald's ice cream contain xylitol, a type of sugar that is harmful to dogs? This claim contains falsehood and some truth: No, McDonald's ice cream does not contain xylitol. A spokesperson from McDonald's USA told Lead Stories that its "soft serve, found in our cones and other desserts, does not contain xylitol." However, according to the FDA, xylitol poisons dogs and could become deadly, if ingested.
Just so everyone knows. McDonalds ice cream has xylitol sugar in it. Don't feed any of their ice cream to your pets. Xylitol sugar is toxic to dogs and will kill them in a hour. Please...
This is what the post looked like on Facebook at the time of writing:
In the abstract of this peer-reviewed, scientific article, xylitol is described as a sugar alcohol that is commonly used as a sweetener. It even has some health benefits to humans.
The McDonald's ice cream ingredients are available to read on the company's website. The ingredients for its vanilla cone (archived here) are: Milk, Sugar, Cream, Corn Syrup, Natural Flavor, Mono and Diglycerides, Cellulose Gum, Guar Gum, Carrageenan, Vitamin A Palmitate. Here and here are the ingredient lists for its chocolate ice cream and vanilla bean ice cream, respectively -- neither contain xylitol. We contacted McDonald's and McDonald's USA sent Lead Stories an email on April 15, 2022, disputing the claim:
These claims are false. Our soft serve, found in our cones and other desserts, does not contain xylitol.
Xylitol could poison your dog if ingested, according to the FDA. The FDA recommends that if a dog has recently eaten a product that contains xylitol, the owner takes them to an emergency veterinary clinic immediately. Further down on the FDA page about how xylitol is poisonous for dogs, there is a list of foods that may contain xylitol.
