When it is done

Thermometer for chuck roast: take it off at 205°F; FDA safe minimum 145°F. Take it off 205°F Safe from 145°F
Take it off at
205°FPull temperature: the internal temperature at which the meat comes off the smoker, read with a food thermometer whose tip sits at the center of the meat.
Safe from
145°FFDA safe minimum: the internal temperature the FDA gives for Beef, pork, veal and lamb (chops, roasts, steaks), as measured with a food thermometer. The meat must reach it before it is served.
Rest
3 minRest: the minutes the meat stands off the heat before it is cut. The FDA gives Beef, pork, veal and lamb (chops, roasts, steaks) a 3-minute rest at 145°F.

Cited guides take chuck roast to 205°F, well past the FDA minimum of 145°F, for texture rather than safety: ThermoWorks brings collagen-rich cuts to 195–205°F so their connective tissue breaks down.

Times are estimates for planning. Meat is done when a food thermometer reads the safe minimum internal temperature, not when a timer ends.
