(NEXSTAR) – Popular gummy bear manufacturer Haribo issued a recall in the Netherlands after some of its “Happy Cola” sweets reportedly tested positive for cannabis.

“There are bags in circulation with sweets that can lead to health complaints, such as dizziness, when consumed,” the Netherlands Food and Consumer Product Safety Authority (NVWA) warned in a news release Thursday.

So far only three bags of “Happy Cola F!ZZ” were affected, but the German candy maker is recalling its stock of the product. The Netherlands recall is confined to 1-kilogram bags of Happy Cola F!ZZ with a best-before date of January 2026 and the product code L341-4002307906.

The recall is confined to the Netherlands, as of Thursday, and all other Haribo products are safe to eat, according to the NVWA.

Several people, including at least one family, became “quite ill” after eating the candy, prompting a police forensic investigation, according to local media.

“We want to know exactly how this got into the candy and how the bags ended up in the store, police spokesperson Chantal Westerhoff told Provinciale Zeeuwse Courant, one of the oldest newspapers in the country.

Police also notified the NVWA, which is still investigating the incident.

“Cannabis was found in the cola bottles in question,” NVWA spokesperson Saida Ahyad confirmed to Agence France Presse, referencing the shape of the candy.

The German confectionery company said Thursday the source of the alleged contamination is not yet clear. A Haribo spokesperson told the BBC that the company takes the incident “very seriously” and is working with police to “establish the facts around the contamination.”

It has not been confirmed whether the candy was a genuine, unaltered Haribo product. Haribo did not immediately return Nexstar’s requests for additional information.

Federal regulators in the U.S. previously warned marijuana edible manufacturers in several states to stop making products that imitate snack brands that are popular among children.

Last fall, Dayton Children’s Hospital reported it had seen an uptick in cases involving children accidentally consuming cannabis edibles.

“Edible marijuana products can look just like regular candies and snacks, making them incredibly dangerous for children,” the Ohio hospital said.
