160°F meat, 165°F poultry: the USDA jerky rule no dehydrator dial satisfies
Last reviewed July 2026.
The numbers come from USDA's Food Safety and Inspection Service. Its jerky guidance recommends heating meat to 160°F and poultry to 165°F before the dehydrating process — those are the temperatures at which the bacteria of concern (E. coli O157:H7 and Salmonella among them) are destroyed.
The part the marketing never quotes is the mechanism. USDA's explanation of why the pre-heat matters: inside a dehydrator or low oven, evaporating moisture absorbs most of the heat — so the meat itself doesn't begin to rise toward air temperature until most of the moisture has left it. By the time the meat can get hot, it's already dry, and dry heat kills far less effectively. That's why a 165°F dial setting is a claim about the air, not the meat — and why the rule is the same for a $40 unit and a $400 one.
The two USDA-consistent routes
| Heat before | Bring the meat to 160°F (poultry 165°F) internal — typically in an oven or by boiling in marinade — then dehydrate at your unit's highest setting. |
| Heat after | Dehydrate first, then heat the finished strips in an oven. One manufacturer — Presto — prints this step in its own instruction book: a 275°F oven for 10 minutes after drying. |
Either route reaches the number the dial only gestures at. Neither costs anything.

How this shapes the table
Because the oven step is the answer on every row, the max-temp claim can't earn a unit a safety verdict — it can only be checked for honesty. A published 160°F+ maximum is a real, checkable spec. A "jerky" pitch over a published sub-160°F maximum is a contradiction on the label. And a big number that exists only in listing copy is a claim with nothing behind it.
