Try to understand that injuries, abuse, etc. at day care are actually quite rare if it is a good day care. Yes it can happen anyhere, but it can happen at home too, so it's not practical to worry about it.
I recommend finding a clean day care which separates the kids by ages (my day care separeates classes by 6 months so my daughter is in the young 2 class right now) and has age approrpiate toys. Then just stop by. Not first thing in the morning, lunch/nap or at closing, though. Stop by between 9 and 11 or 2 and 4 when kids are playing and teachers are busy. Then you can see how they interact with the kids, if any of the kids might be cuasing problem, and if they clean after diapers/potty.
It's hard to know which day care is "best" but you can usually tell the bad ones from the good ones as they will be dirty, kids just running around, no structure, etc. And if you get a bad feeling, trust it.
