I saw a recipe for a Summer Salad that said to sprinkle raw corn on top for a "crunch" effect - I've never eaten raw corn and was wondering if it was safe. I'm guessing hard to digest at the least....
If your area has an issue with wild pigs or a large number of deer wandering through croplands and gardens, uncooked vegetables may be unsafe. Otherwise, it should be fine, and depending on the variety of sweet corn, downright delicious.
Corn is normally processed by soaking it in alkali-water, a process called Nixtamalization
The known benefits of this process are increased nutritional value and drastic reduction of mycotoxins if these are present.
I personally would discourage eating raw corn just to be safe. But there are currently no other known factors than the ones mentioned above.
