i just noticed the oven has been off for 30 minutes, the turkey itself has only had 30 minute before i switched it off unknowing.
will it be ok if i switched the oven back on or will i cause my family to have food poising

Yes - just make sure it is cooked through thoroughly. Is it a whole turkey or a bit of one?

a whole turkey

Get the oven back on and make sure it's well cooked.
