What is the best way to reseal this junction, but preserve

Silicone adhesives, as far as I know, are not particularly toxic in the
first place, and I doubt a properly cured bond would leach.

Can food be placed in contact if I use superglue? Doubt it, but need
confirmation.

Superglue isn't stable. It can be weakened simply by contact with water.

I'm inclined to agree with the poster who suggested buying a new pot.


not an option


Short answer: GFGI


Go to a pet store and get a tube of aquarium seal. It's a silicone
adhesive (which of itself is totally nontoxic), plus whatever is used
for a catalyst won't harm fish, even after very long exposure in
non-changing water. If it won't hurt them, it sure won't hurt you.

Clean all the surfaces with something like a "green scrubber", and apply
the silicone as a decent-thickness fillet. You can smooth the stuff with
a finger wetted with mineral spirits (which will evaporate by the time
the silicone is cured).
