Is There a USDA-Approved Electric Pressure Canner? No, and No Canner Is

If you went looking for an approved machine, that was a sensible thing to do. You want the jars on your shelf to be safe for your family. Here is where approval stands, and what you can lean on instead.

Who says what?

• Presto's FAQ: Asked if the USDA and the National Center have approved its digital canner, it answers no. Neither one certifies or approves home canning equipment.
• Presto's spec sheet: It claims the machine meets USDA home canning guidelines. Its own footnote says the USDA doesn't certify or approve home canning equipment.
• Kansas State, sharing the National Center's advice: The National Center doesn't recommend or approve any canner brand. The USDA doesn't approve specific canners. The USDA or a university lab has not evaluated this appliance.
• Penn State: The maker claims the digital canner follows USDA guidelines. The USDA and the National Center endorse no canner.
• North Dakota State University: It describes the Presto Precise in a good light. It also says it does not endorse products or companies.

Even the friendliest extension source we read makes no claim of approval. Penn State adds the same kind of note to its own article.

What about the seal on the box?

The small round badge on some Presto materials is Presto's own. Kansas State, sharing the National Center's advice, says Presto made it. It is not an official USDA seal and does not mean USDA approval. The same note says even official USDA symbols can't be used to suggest the USDA endorses a product.

If a listing or video points to a seal as proof, set that aside. Our Presto Precise page covers Presto's other claims. What the National Center says lists its statements in order.

What gets mistaken for approval?

• "Follows USDA guidelines." That is the maker's statement about its own product. The National Center (through Kansas State) and Penn State say Presto's research can't be checked. Nobody outside the company has published test results for Presto Precise canners. One expert reply from Ask Extension (a free question service) says the same about outside testing and USDA endorsement.
• "ETL Approved" or "Listed." This is an electrical safety mark. It says nothing about food safety. The NESCO NPC-9 is, in our reading, in the group Penn State says it can't recommend, because research on cooker-canner combos is missing. Penn State names no brand. See the full safety discussion.
• "Uses USDA recipes" or a canning button. A recipe source says nothing about the machine. The National Center does not support USDA canning instructions in electric multi-cookers, even with canning buttons. Our Instant Pot page explains.

What should you look for instead?

With no seal to find, ask plainer questions:

1. What type is it? Stovetop, canning-only electric, cooker-canner combo, water bath or multi-cooker. Our guide to electric canner types sorts them.
2. Does the maker say it holds at least four quart jars, upright, with the lid on? That is one condition among several. It doesn't prove the heat matches.
3. Whose tested recipes will you use, and does your manual agree? See where tested recipes live and canner manuals.
4. Are you fine with what nobody knows yet? For a canning-only electric machine, that means trusting the maker's testing, which is not published. If you'd rather not, a stovetop canner is the type the National Center says its instructions were written for.

This is a reading of the sources, not a safety ruling. To talk it through with someone local, call your state's university extension office (free local food-safety advice).
