Swiss police said they are investigating a 7-year-old girl's discovery of a condom in her McDonald's Happy Meal.

Fribourg state police said the mother called them after the girl discovered the condom among her French fries.

Police said Monday they were investigating where the condom came from and how it got into the Happy Meal. They said an analysis was being done to determine if the condom posed a health risk.

McDonald's in Switzerland declined to comment because of the ongoing investigation.
