I absentmindedly left 5 lbs of steelhead trout in an insulated bag (no ice) in my car in the garage. Outside temperature was low 70's, garage was a comfortable temperature. The insulated bag is advertised as keeping food cold for 4 hours. The fish was in the bag for 6 hours. The internal temperature was 68 degrees, just a bit under room temperature. There was no odor coming from the package. What do you think? Safe to eat or toss it?
