Plain, air-popped popcorn without butter or salt is generally a fine occasional treat, but unpopped kernels are a choking hazard and butter/salt toppings add unnecessary fat and sodium.
Popcorn itself carries no toxicity concern in its plain form. The practical risks are unpopped kernels (a genuine choking hazard) and the toppings typically added for human consumption — butter, salt, and sometimes flavoured seasonings that can include onion or garlic powder.
