Yes, it's completely safe.
However, I camped at Flamingo a few weeks ago and the mosquitoes were horrendous. They were manifold and super aggressive, which had a serious impact on our enjoyment of the trip. I'm sure it varies a lot with the weather, but bear that in mind.

There are two campgrounds with different features and policies
Flamingo http://www.nps.gov/ever/planyourvisit/flamcamp.htm
Long Pine Key http://www.nps.gov/ever/planyourvisit/longpinecamp.htm
You can also opt for backcountry camping http://www.nps.gov/ever/planyourvisit/backcamp.htm
If you meant safe then yes, it is quite safe once you take the usual common sense precautions
