Alan - good point, we'd hear about it if it were a problem. High temperature would discolour beeswax though, and AFB spores will withstand at least 10 minutes at 100 C so the melting / casting process is very unlikely to destroy them.
However the infectivity is perhaps a major factor - AFB spores need to be fed to larvae of 1-2 days age, otherwise infection is extremely unlikely for the number that might be lurking in the wax of a cell. Any wax builders have generally progressed well beyond the brood feeding stage, hence unlikely for cross-contamination of brood food.
Pesticides? Yes, more likely IMHO, particularly beekeeper-administered ones.
