This is crap. In the field of chemistry there is a very clear definition of the terms "organic" and "inorganic," "Organic" pertains to any substances incorporating the element carbon in its molecules. So-called, because the substances formed by living beings fall into this category. "Inorganic" pertains to any substance that does not incorporate carbon in its molecular structure. So-called because they correspond to normally non-living material (e.g., salt).

If this machine is making an automatic database comparison, it is most likely failing to make a pattern match with anything in its library and defaults to "inorganic" as an output. But it hasn't actually identified anything. A further chemical analysis is needed to specifically identify the unknown substance. (The mother should have pursued this further. And paid attention during high school chemistry class.)

Automatic determination of toxicity or nutritional value is at best an estimate based on the assumption of some basic chemistry.

This does not mean that there is nothing wrong with the breast milk, but only that there is something unknown going on. Calling it "inorganic" or "toxic" is unjustified and incorrect without a specific identification. Food value? One wonders what would happen if you fed it a French fry.
