It is true that sterility can never be guaranteed but proper industrial sterilization makes your chances really good.

"At present, a sterility assurance level (SAL) of 10–6 is generally accepted for pharmacopoeial sterilization procedures, i.e., a probability of not more than one viable microorganism in an amount of one million sterilised items of the final product."

If you keep reading you see that for medical devices they may have to settle for a lower SAL, maybe even 1 in 1000, if the device cannot handle more aggressive conditions.

I cannot yet find a reference that discusses the SAL of a steam autoclave, much less a pressure canner. However I did find a reference suggesting that the same one in a million chance is expected for food products, which are basically pressure canned.

"The objective is the universal maximum probability of a single nonsterile unit (PNSU) in 106 units (a PNSU of 1 × 10–6 for any individual item). This is nothing more than an acceptable risk of contamination, whose origin (in the food industry) goes back many years."

(What complicates this discussion is that the reduction of microorganisms is also discussed in terms of logarithmic reduction. But if you kill off all but one in a million bugs in a jar, that is not the same as having the processed item's probability of nonsterility being one in a million.)

Anyway, my take is things like grain jars and LC can be treated as if truly sterile if processed correctly. After all, we can food the same way and it is expected to last for years. Additional complications like leaving jar lids loose during processing, or the quality of our filter patches probably hurt our odds, but for now my philosophy is to process carefully, and then trust the jars. If I happen to leave a sterile grain jar on a shelf and it gets gross in a couple of months, I will reassess.

(Hmm, actually, I should do that... make a test jar with my regular lid style, and just leave it alone to see what happens in the next year.)

When you say daily for the mini/microdose, is that without any breaks at all, so continuously?
