The way I read this, just washing their dishes together seems unlikely to share the infection, assuming you washed & rinsed them thoroughly.
On the other hand, some can apparently carry this for some time without symptoms, so you should probably assume all your animals are exposed
and that your corn snake may even have been exposed from another reptile in your collection if you handled them one after another. I guess you'll
have to keep watching for symptoms? What did your vet advise?
Rest in Peace, Tezzeret.
