Salmonella dies quickly at 165°F (74°C); lower heat can also work when food is held long enough.
Food safety comes down to time, temperature, and a reliable thermometer. Salmonella is sensitive to heat, and once the center of food reaches the right temperature—held for long enough—the bacteria can’t survive. This guide explains kill temps, practical time–temperature paths, and how to check doneness without guesswork.
Safe Internal Temps By Food Type
Before diving into kill curves, it helps to know the standard minimum internal temperatures for everyday cooking. These targets are designed for home kitchens and cover the most common foods people cook during the week.
| Food | Minimum Internal Temp | Notes |
|---|---|---|
| Poultry (whole, parts, ground) | 165°F / 74°C | Instant kill at this temp; check the thickest spot near bone. |
| Ground Beef, Pork, Lamb, Veal | 160°F / 71°C | Grinders mix surface bacteria throughout; temp must be higher than steaks/roasts. |
| Whole Cuts (beef, pork, lamb, veal) | 145°F / 63°C + rest | Let steaks/roasts rest 3 minutes so carryover heat finishes the job. |
| Fish & Shellfish | 145°F / 63°C | Or cook until flesh is opaque and flakes easily with a fork. |
| Egg Dishes (quiche, casseroles) | 160°F / 71°C | Scrambles should not be runny; use pasteurized eggs for undercooked styles. |
| Leftovers & Casseroles | 165°F / 74°C | Heat evenly; stir large dishes so cold spots don’t linger. |
Those targets align with public-health guidance that home cooks can follow every day. For reference charts and thermometer how-tos, see the federal safe minimum temperature chart. For eggs and egg dishes, FDA also provides clear directions on doneness and pasteurized options you can use in recipes that would stay undercooked by design, such as certain sauces or ice creams; details are here: FDA egg safety.
Temperatures That Kill Salmonella Fast
Heat knocks out Salmonella in two ways: by reaching a high enough instant temperature, or by holding a slightly lower temperature long enough to deliver the same overall kill. In home kitchens, the first path is simpler: hit 165°F (74°C) in the center of poultry and you’re done. That’s why that number shows up across consumer guidance.
For other foods, you still want to cook to their safe internal temp—160°F (71°C) for ground meats and 145°F (63°C) plus a rest for whole cuts—because the contamination pattern and structure are different. Ground meat needs more heat since the grinding step moves surface bacteria to the middle. Whole steaks can be safe at a lower center temp when seared properly on the outside and rested, which allows heat to equalize.
Why Time Matters Alongside Heat
Bacteria die across time as well as temperature. This is why a steady hold at a lower number can deliver the same safety outcome as a brief spike at a higher one. Food scientists describe this with “D-values” and “z-values,” which basically translate to how long it takes to reach a multi-log (multi-million-fold) reduction at a given temperature, and how sensitive that process is to temperature changes.
You don’t need to run lab math in the kitchen. What you need is a clear target and a way to verify it. A digital instant-read thermometer gives you that verification without cutting food open and losing juices. Insert the probe into the center of the thickest area, avoiding bone or fat pockets that can read high or low.
What The 165°F Target Delivers
At 165°F (74°C), poultry meets a high lethality standard rapidly—fast enough for home cooking without a hold. That’s why many recipes and public charts point to the same figure: it’s a safe endpoint that doesn’t require timing tables. If you cook chicken thighs or a whole bird to 165°F in the deepest part and the surrounding areas are around that point, Salmonella will not survive.
Hold Times At Lower Temps
Some cooking methods, like sous-vide, aim for slightly lower center temperatures with a controlled hold to keep texture tender. In that case, time is part of the safety plan. Keep in mind that fat content, thickness, and circulation all influence how fast the center warms and how evenly heat is delivered.
Practical Paths For Home Cooks
If you prefer to avoid the complexity, stick with the everyday targets from the table above and verify with a thermometer. If you enjoy precision methods, pick a validated time–temperature path. Industry guidelines show many combinations that reach the same kill. The list below gives kitchen-friendly milestones that map to those principles.
Suggested Home Targets With Holds
- 165°F (74°C), no hold: Quick kill; best for conventional roasting, grilling, and sautéing.
- 160°F (71°C), short hold: Works for thin poultry cutlets in a steady pan or controlled bath.
- 155°F (68°C), roughly a minute hold: Suits gentle methods when texture is a priority.
- 150°F (66°C), a few minutes hold: Requires tight control and patience; not ideal for uneven cuts.
These are practical waypoints, not lab-table substitutes. If you’re new to time-based cooking, start higher and simpler, then dial in once you’re comfortable with your thermometer and pan or bath behavior.
How Resting Makes Food Safer
Carryover heat keeps working after you turn off the burner or pull food from the oven. A steak at 145°F (63°C) can climb another couple of degrees as it rests, while temperature equalizes from the exterior inward. That rest also improves juiciness, so you get better texture along with the safety you want.
Measuring Heat Correctly
A thermometer reading is only as good as its placement. Slide the tip into the center of the thickest zone and pause until the number stabilizes. For a whole bird, test the breast’s deepest point and the innermost thigh near the bone, avoiding cartilage. For patties, slide the probe horizontally from the side so the sensor sits in the core.
Choosing A Thermometer
Instant-read models make quick checks easy, while leave-in probe thermometers monitor large roasts through the cook. Avoid guessing by color; juices can run clear before the center is hot enough, and some meats stay pink even when safe due to myoglobin chemistry. The only reliable check is a thermometer.
Cross-Contamination Control
Heat solves the bacteria inside the food. Raw juices on boards and hands are a different problem. Keep raw poultry on a dedicated cutting board and switch tools once raw prep is done. Wash hands with soap and warm water after handling raw meats and eggs. Keep salads and ready-to-eat items away from raw prep areas until you’ve cleaned down your station.
When Undercooking Is Risky
Burgers and meatloaf need a full 160°F (71°C) because their middles are no longer protected by an intact surface. Chicken must reach 165°F (74°C) all the way through. Egg dishes need 160°F (71°C) unless you’re using pasteurized eggs. If a dish stays intentionally runny or glossy, switch to pasteurized products for the same texture with a safety margin.
Time–Temperature Paths To Kill Salmonella
The combinations below reflect lethality concepts found in widely used guidance for ready-to-eat meat and poultry. They show how different temps can achieve similar safety when paired with an appropriate hold. In home kitchens, aim for the higher end if thickness is uneven or your heat source fluctuates.
| Center Temperature | Typical Minimum Hold | Kitchen Notes |
|---|---|---|
| 165°F / 74°C | No hold needed | Fast, simple endpoint for poultry and mixed leftovers. |
| 160°F / 71°C | Dozens of seconds | Use for thin cuts under steady heat; verify in the center. |
| 155°F / 68°C | Around 1 minute | Works with uniform pieces; watch thickness and circulation. |
| 150°F / 66°C | Several minutes | Precision methods only; avoid for bony, uneven cuts. |
The exact seconds and minutes can shift with product type, fat level, thickness, and process control. Commercial plants use detailed tables and validation studies to hit a specific log reduction target. For home cooking, the consumer charts and the 165°F poultry standard give you a clean, repeatable path to safety without chasing decimals.
Applying The Numbers In Real Meals
Roast Chicken
Set the oven to a stable temperature and roast until an instant-read thermometer in the deepest breast hits 165°F (74°C). Check the thigh near the bone as a second point. If one zone lags, give it a few more minutes and recheck.
Weeknight Burgers
Cook patties on a hot skillet or grill until the center reaches 160°F (71°C). Slide the probe in from the side so you read the true core. Rest a minute to manage juices, then serve.
Leftovers Night
Large casseroles can heat unevenly. Reheat to 165°F (74°C), stir, and check again in a few spots. Microwaves can leave cold pockets; stirring and standing time help even things out.
Why Some Cuts Have Lower Targets
Whole steak has a clean interior and a contaminated exterior. A hard sear on the surface addresses that outer layer, so the center doesn’t need to climb as high as ground meat. Once you slice or grind, the inside is no longer protected. That’s the entire reason burger targets sit above steak targets.
Egg Dishes And Safer Options
For custards, quiche, and breakfast bakes, aim for 160°F (71°C) in the center. If you want soft styles like sunny-side eggs or silky sauces that don’t reach that number, use pasteurized shell eggs or pasteurized liquid egg products. FDA’s consumer guidance lays out these options plainly; you can skim it here: FDA egg safety.
Thermometer Habits That Stick
- Keep an instant-read thermometer in the same drawer as tongs so you reach for it every time.
- Calibrate or check accuracy now and then in ice water (32°F / 0°C) and boiling water (212°F / 100°C at sea level).
- Wipe the probe with a clean towel after each test and wash it at the sink once you’re done cooking.
- Test a couple of spots in large roasts or casseroles; take the lower number as your guide.
Storage And Cooling After Cooking
Safety doesn’t end when the burner turns off. Cool leftovers fast. Spread shallow layers in flat containers so heat can escape and move dishes into the fridge within two hours. Reheat to 165°F (74°C) and stir. Good cooling and reheating habits block any survivors or re-contaminants from bouncing back.
Big Picture: Heat, Hold, And Confidence
When you reach the right internal temperature—and hold it when the target calls for it—you neutralize Salmonella. The fastest path is simple: 165°F (74°C) for poultry, 160°F (71°C) for ground meats, 145°F (63°C) plus a rest for intact steaks and roasts, 160°F (71°C) for egg dishes, and 165°F (74°C) for leftovers. A thermometer tells you when you’re there. Clean handling keeps the rest of the kitchen safe while you cook.
