ELI5: How come you can never get crappy toys in cereal any more?

Boy, as a kid, shreddies always came with something inside. 

I think its to do with safety. The toy might end up being eaten by a child. They might choke and die, leaving a massive lawsuit against the cereal producer. 

I also think US government regulations affect this. There are prize-containing candies called Kinder Surprise that are made in Europe, but are banned in the US due to safety regulations.
