Why jerky must hit 160°F
The dehydrator doesn't make jerky safe — a heat step does.
Undercooked home-dried meat has caused real outbreaks. Follow USDA guidance and discard anything you're unsure about.
It's a natural assumption that hours in a dehydrator must kill anything harmful. It doesn't. The USDA is explicit: drying temperatures alone are often not hot enough to reliably destroy Salmonella and E. coli O157:H7, and as the meat dries, surviving bacteria become more heat-resistant. A separate heat step is what makes jerky safe.
The kill-step temperatures
| Meat | Safe internal temp |
|---|---|
| Beef, venison, other red meat | 160°F (71°C) |
| Poultry | 165°F (74°C) |
The meat must actually reach that internal temperature — measured with a thermometer, not assumed from the dehydrator's setting.
Heat before or after drying?
USDA allows either order, and both work:
- Heat first — steam or roast the strips to 160°F, then dry. This kills pathogens while the meat is still moist and least heat-resistant, which is the more robust approach.
- Heat after — dry as usual, then finish in a 275°F oven until the meat reaches 160°F. Convenient, but bacteria are tougher to kill once dried, so don't shortcut the final temperature.
Dehydrator temperature still matters. Run the dehydrator at 130–140°F so the meat dries fast enough to limit bacterial growth during the process. A low-and-slow setting that lets meat sit warm for hours is the opposite of what you want.
Gear this guide uses
Hitting the kill step reliably comes down to measuring the meat's real temperature and drying it fast.
- The 160°F/165°F kill step has to be measured, not assumed — use an instant-read thermometer on the thickest strip.
- A dehydrator with an adjustable thermostat lets you run the 130–140°F drying temperature this guide recommends.
- For the post-dry finish, a leave-in oven thermometer confirms the meat reaches 160°F in the oven step.
