Is slow roasted at 170 for 24 hours safe?

From what I've read turkey should never be roasted under 325 degrees. I agree with Stephanie, your turkey was in the danger zone too long.

What are you slow roasting? Is it 170 Fahrenheit or Celsius? Has it reached a safe internal temperature?

It sounds as if it may have been in the "danger zone" longer than recommended.
