The FDA forbids non-food items being sold inside of food items:
The Federal Food, Drug, and Cosmetic Act at Section 402(d)(1) says that a confectionery product with a non-nutritive object, partially or totally imbedded within it, cannot be sold within the United States, unless the FDA issues a regulation that the non-nutritive object has functional value and is non-injurious to health. No such regulation has been issued.
