Untersuchungen zum Vorkommen von Antibiotika und Sulfonamiden in bayerischer Konsummilch mittels enzymimmunologischer Verfahren

Eighthundred consumer milk samples from all Bavarian dairies were analysed from March 1992 to March 1993 for residues of several antibiotics (chloramphenicol, tetracyclines, streptomycines) and sulfonamides by using enzyme immunoassays. The samples were additionally assayed in a microbiological test system (Brillantblack reduction test). Three samples were positive in the microbiological test. None of the 800 samples was positive in the immunochemical tests, which had detection limits for the individual analytes well below the respective maximum residue limits.
