"You have to have a vet write script for foulbrood, but you didn't have foulbrood"

It seems obvious that the problem was bacterial or the terra would not have been effective.  It is also perfectly legal for a Vet (just like a human MD) to prescribe a drug for an off label use.  Do not confuse pesticide laws with drug laws.  While it is illegal to use a pesticide off label it is legal and dirt common to use drugs off label.  It is a practical impossibility to test every antibotic against every known and unknown bacteria so there is little choice but to use them off label.

HL Mencken said: "The whole aim of practical politics is to keep the populace alarmed — and hence clamorous to be led to safety — by menacing it with an endless series of hobgoblins, all of them imaginary. "
