Just started smoking my own meats about a month ago, used my smoker 4 times so far. I've smoked 2 pork butts so far. First one was around 5.5 lbs and stayed on the smoker for 13-14 hours. It never got over 175, but held 175 for probably 4 hours and wouldnt budge so I pulled it and let it rest for about 5 hours wrapped in a towel and in cooler while I slept. The butt was tender and and tasted perfect. I noticed the next day I had some minor stomach cramps with some diarrhea, and a buddy had the same symptoms as me who ate some. On my next butt I smoked it was around 5lbs. Smoked it for 10hrs, didnt put probe in until after 4hrs. I didnt notice the temp when I installed the probe, also didnt inject either.I pulled the second one at 200. I cooked this one on the lower rack of my WSM. It was good and all but seemed alittle tougher than the first one. Both butts went straight from butcher to fridge, rubbed and straight to the grill. Noticing today after eating on the second butt I'm feeling the same way?? I can maybe understand why i felt cramps on the first one but the second one was cooked to 200. I've ate pork all my life and never had an issue....WTF??
