[Drug residues in poultry (author's transl)].

The following microbiological tests: the Bacillus subtilis BGA (Bundes-Gesundheitsamt) test and Sarcina lutea test as well as the test bacteria Bacillus stearothermophilus var. calidolactis and E. coli were used to examine whether drug residues were detectable in broiler chickens during and after treatment with various drugs. With the exception of the occidiostat Esb3, residues were not found to be present using the two above tests. On the other hand, residues of a number of drugs were detected in some interior organs and faeces during treatment when the other test bacteria were used. Residues were no longer detected in the faeces, however, within twelve hours after treatment had been discontinued.
