Anhalt tells TMZ he was outside his Beverly Hills home on Tuesday "sunbathing and eating Kaiserschmarrn" -- which is totally normal -- when he somehow swallowed a bee ... that ended up stinging his throat on the way down.
Anhalt says he suddenly "could not breathe and turned blue" ... and had to be rushed to a local hospital.
We're told Anhalt is still in the hospital ... and it's unclear when he'll be able to eat Kaiserschmarrn again.
