Why can’t babies eat honey?

I know the basic answers “Honey can contain spores of Chlortridium botulinum which babies can’t digest”. But I want a deeper answer, why can’t babies digest it but adults can? It also raises another question, some adults get botulinum toxin from improperly canned food because the spores activate in low oxygen environments, but why is it that why the spores are in the canned food adults can’t digest it but they can when it’s in honey?

It’s *Clostridium botulinum*.  Infants have a higher stomach pH, so their stomachs are less acidic than that of children and adults. The spores can survive in their stomachs and then colonize the intestines and cause botulism. In children and adults the spores are destroyed so infection is not a worry (adults can get this type of infection, but it is very rare). 

Adults get botulism when they eat a food that has had the bacteria growing in it and ingest the endotoxin botulinum.  The bacteria die, but the large dose of botulinum causes rapid poisoning, versus a baby with a *Clostridium botulinum* infection, where the bacteria grow slowly and produce the toxin as they multiply, causing gradually increasing muscle weakness.
