Real beer isn't sterile, nor is it made in sterile surroundings. It is
made in sanitized surroundings. Look up the difference.

If the beer was cloudy, two possibilities: One is "chill haze"--this is
protein that was not settled out of the beer during brewing or lagering
and it becomes apparent when the beer is cold. The other possibility is
active yeast that continued to grow in the can (i.e., it wasn't
pasteurized correctly).

Either way, it's perfectly okay to drink.
