Time for an "intervention!" You all are making way too much out of the "food grade" issue for a tiny dab of silicone at the probe end, where it meets the wire. This should never be in contact with the meat, so what's the worry? And, it's such a minimal amount, it probably wouldn't kill you if it did accidentally touch the meat. Just use any high-temp silicone, and get onto smoking something! We face bigger hazards eating at any fast food joint, or regular restaurant, every time we eat there!
