If I recall there is an FDA rule that says you can’t sell a food item that contains a non edible thing that could cause someone to choke.

Edit: Here it is

Section 402(d)(1) of the Federal Food, Drug, and Cosmetic Act provides that confectionery having partially, or completely imbedded therein, any non-nutritive object is adulterated unless FDA has issued a regulation recognizing that the non-nutritive object is of practical functional value to the confectionery product and would not render the product injurious or hazardous to health.
