Just used our Masterbuilt Sportsman elite 2 door propane smoker for the first time. We smoked the ribs at 225- 250 degrees for just under 3 hours. After taking out ribs we noticed the paint on then inside had bubbled up and could peel away easily. A few weeks ago before smoking any food we sprayed it with oil and ran the smoker at 350- 400 for 3 hours. There were no visible problems with the paint until after smoking the ribs. Could the paint be toxic? Is it still safe to eat the ribs? Sorry for the bad picture.
