> It can be said that, in a general way, European beekeepers use those substances no longer.

Yeah, and on what do you base this rash statement? It is widely known that beekeepers use whatever they can get their hands on. Is the following current enough for you? 

> With the widespread occurrence of foulbrood diseases and the limited number of products authorised for use in controlling them, there exists a potential for extra-label abuse of antibiotics that are registered for other agricultural applications. This potential abuse is exemplified by data reported under the European Commission’s Rapid Alert System for Food and Feed (RASFF). From February 2002 until February 2011 there have been 238 notifications issued for specific veterinary drug residues in honey (RASFF, 2011). Veterinary drugs listed amongst the notifications include numerous sulphonamides, chloramphenicol, tetracyclines, macrolides (including tylosin and erythromycin), streptomycin, lincomycin, fluoroquinolones, and metabolites of nitrofurans.
