I don't know if just a coincidence but after smoking some rabbit the night before I woke up the next morning feeling run down and just bad feeling headache, no energy. etc. my wife didn't eat any and was fine..
That night and the next night, I had headache chills,uncontrolled shaking, cold clammy profuse sweats, cramps, diarrhea, aches, pains, headache, no energy, But no nausea or vomiting... I basically slept for 2 days. There are no flu going around here, And I hadn't been around anyone for days, and I rarely am sick. 4 days later I'm feeling ok.
I brined the rabbit for 6 hours with cure and spices, I smoked the rabbit @ about 200 degrees for several hours on my traeger.
If it wasn't food poisoning I don't have any idea what it was. I've been smoking game and meat since the late 60's and never have had a problem.
maybe too much reading about the dangers of smoking your own food lately LOL
My reason for the post is trying to tell the differences between food poisoning and flu type symptoms. The vomiting and nausea may be the key.
