it said for jelly to seal with paraffin, isn't that a bit dangerous?

Rationale: pinholes or cracks in the paraffin can allow mold spores to
enter the jelly and reproduce. Long term harm of mold isn't entirely
known; there are some that are known to cause cancer in animals, but
tests and research (AFAIK) haven't been done w/re to humans.

Not only are the molds dangerous, especially to allergy-prone people, but
the by-products of some molds (mold poop?) produce toxins, which are also
dangerous. Why reheating moldy food won't necessarily get rid of all the
baddies. From the website somebody quoted here recently. Univ of Georgia?
