Cadbury’s Canadian parent company has pulled specific batches of its Dairy Milk Oreo candy bars from shelves across the country after discovering the chocolate bars may contain pistachio that never made it onto the ingredient label.
The Canadian Food Inspection Agency issued the food recall warning on July 24, 2026, flagging the undeclared tree nut allergen and warning that eating the affected bars “may cause a serious or life-threatening reaction” for anyone with a pistachio allergy or sensitivity. The agency confirmed that people have already gotten sick from eating the bars, though it has not released a count of how many reactions occurred or how serious they were.
Because of the danger involved, regulators slapped the recall with a Class 1 designation the label reserved for cases where there’s a high likelihood that eating the product could lead to serious illness or death.
The recall is narrow in scope, covering only the 38-gram single bars and 12-packs of Cadbury Dairy Milk Oreo candy, which the company says may contain pistachios not listed on the packaging. The products were sold both in stores nationwide and online.
Shoppers who have either product at home are being told to check the UPC code and best-before date against the official recall listing. Anyone holding onto an affected bar shouldn’t eat it, serve it, sell it, or hand it off to someone else the CFIA says it should either be tossed in the garbage or brought back to the store where it was bought.
The recall didn’t originate from a government inspection it was the company, Mondelez Canada Inc., that flagged the problem in the first place. Since then, the CFIA says it has been checking in to make sure retailers are actually pulling the bars from store shelves.
The agency also cautioned that this might not be the end of it. A food safety investigation is now underway, and CFIA officials say that probe could turn up additional products that need to be recalled.
Tree nut allergies remain among the most common food sensitivities in Canada. A 2020 study found that roughly 1.7% of Canadian adults self-report a tree nut allergy, with the figure climbing to 2.6% among children. Researchers have also noted that cases of anaphylaxis triggered by tree nuts have been on the rise over the past ten years, making accurate allergen labeling on packaged snacks like this one a genuine matter of consumer safety rather than just a paperwork issue.
This isn’t an isolated incident. Canada has seen a string of similar recalls in recent months, all tied to the same root problem: allergens missing from ingredient labels. Earlier this month, various flavours and sizes of Gummy Gainz protein candy were recalled nationally after a customer complaint and a reported allergic reaction revealed the product contained milk that wasn’t listed on the packaging. Back in April, Galerie au Chocolat had to pull its plant-based chocolates from the market for the identical reason undeclared milk with the CFIA instructing retailers to immediately stop selling or serving the products.
Consumers who have questions about the Cadbury recall or want to report a reaction can contact Mondelez Canada directly or reach out to the CFIA through its public enquiries line.
