Grilling and smoking add real risk that a lot of backyard cooks underrate, mostly because outdoor cooking makes it harder to judge doneness by eye — a piece of chicken can look perfectly browned on a hot grill while still being unsafe in the middle. The numbers below come from the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS), the federal agency responsible for meat, poultry, and egg product safety, specifically its Safe Minimum Internal Temperature Chart and its Grilling Food Safely guidance.
The Core Rule: Color and Time Aren’t Reliable
FSIS is explicit that meat and poultry cooked on a grill tends to brown very quickly on the outside — sometimes well before the inside is actually safe — so a food thermometer, not a cut-and-check or a visual guess, is the only reliable way to confirm a safe internal temperature. USDA also advises against partially grilling meat or poultry with the intention of finishing it later, since that gives bacteria a window to multiply during the gap between the two cooking sessions.
Safe Minimum Internal Temperatures
- Steaks, chops, and roasts (beef, pork, lamb, veal): 145°F, then rest for at least 3 minutes before cutting or eating. The rest isn’t optional — USDA’s guidance treats it as part of the safety standard, not just a cooking tip, because the temperature needs those few minutes to hold and finish destroying pathogens at the surface.
- Ground meat (beef, pork, lamb, veal): 160°F. Grinding distributes any surface bacteria throughout the meat, which is why ground product needs a higher target than a whole steak or roast.
- Poultry, whole or ground, including chicken and turkey: 165°F, measured in the thickest part of the breast or thigh without touching bone.
- Fish: 145°F.
- Egg dishes: 160°F.
- Leftovers and reheated food: 165°F.
Always check the thickest part of the cut, and keep the thermometer probe away from bone or the pan/grate itself — both conduct heat differently than muscle and will throw off the reading.
Cross-Contamination on the Grill
FSIS recommends using two separate plates when you grill: one to carry raw meat or poultry out to the grill, and a different, clean one to bring cooked food back in. Putting a finished steak or chicken breast back on the same plate that held it raw undoes the cooking you just did. The same logic applies to cutting boards — keep one for raw meat and poultry and a separate one for produce, buns, or anything that won’t be cooked further.
Marinades and Basting
Any marinade that’s touched raw meat or poultry should never be brushed on food again once it’s cooking or finished, unless you boil the marinade first to kill off whatever it picked up from the raw meat. If you want sauce for serving, set some aside before the raw meat goes in, or make a fresh batch. Marinating should always happen in the refrigerator, not on the counter — USDA’s general food safety guidance treats the “danger zone” between roughly 40°F and 140°F as the range where bacteria multiply fastest, and a countertop easily sits in that range for hours.
The Danger Zone and the 2-Hour (1-Hour) Rule
FSIS defines the “danger zone” as the range between 40°F and 140°F, where bacteria can double in number in as little as 20 minutes under the right conditions. The general rule is not to leave perishable food, cooked or raw, sitting out in that range for more than 2 hours. At an outdoor cookout in summer weather, that window is cut in half: once the ambient temperature is above 90°F, FSIS’s guidance drops the safe limit to 1 hour. This matters for both ends of an outdoor cook — raw meat waiting to go on the grill should stay in a cooler or the fridge until it’s needed, not sitting on a counter or picnic table, and cooked food shouldn’t linger out in the heat either, particularly things like potato salad or anything with mayonnaise that outdoor cookouts tend to pair with grilled meat.
One More USDA Note
USDA also specifically advises against washing raw meat or poultry before cooking. It doesn’t reliably remove bacteria, and splashing water off raw meat can spread it around your sink and countertops instead — the heat of cooking is what actually neutralizes the risk, not rinsing.
Why This Matters More for Outdoor Cooking Specifically
Smoking and grilling both involve carryover variables — wind, ambient temperature, fuel type, lid position — that make it much easier to misjudge internal temperature than with an oven at a fixed, known setting. A brisket or pork butt can also sit in the temperature danger zone for a while during a long stall (see our separate article on the science of the stall) before climbing back up, which is one more reason a reliable instant-read or leave-in probe thermometer belongs in every outdoor cook’s kit, not just an optional extra.
