how to detect contamination in casings? Is contamination only visible then something strange is poking through the casing layer or could the surface still look okay with contamination inside the mycelium layer?
Reason i ask this: I have some jars of popcorn, that stalled about half way (jars are 2 months old / grow stalled about 1 month ago) This happend due to too dry popcorn (PCed it too long) I dicided to case them anyway, since anything else looked/smelled good Then i emptied the jars for dunking the cakes felt apart, so that colonised and uncolonised corn mixed in the dunking water. (impossible to seperate them now)
I am now thinking of casing this cornmixture anyway, since i have nothing to loose, exept some coir
My concern is now, that they might contaminate due to uncolonised corn in casing, and that i woudlnt recognize it, and maybe then eat posinus mushrooms, then they pin from that casing.

Both. That's visual identification. Any strange smell ?

That's the most probable situation here. You can give it time and see if they colonize but it will take a lot longer. If you spot any contamination, just toss the whole thing. If you manage to get any pins, let them grow, harvest them and break the casing to see if any contam was growing on the inside. If it was, toss the harvest.
