BS EN 16936:2017 presents a method describing the screening on the antibiotics tylosin,
virginiamycin, spiramycin, bacitracin-zinc and avoparcin at sub-additive levels in complete feeding
stuffs and milk replacers by a microbiological 3-plate test.
The limit of detection of the method is 1 mg/kg for avoparcin, tylosin, spiramycin and virginiamycin,
and 5 mg/kg for zinc bacitracin. The presence of other (veterinary) antibiotics may interfere with the
method.
Furthermore, high concentrations of metals (Cu, Zn) may interfere. The method should be used as a
qualitative screening method. Positive results can be analysed further by TLC; for confirmatory
purposes LC-MS is required [1].
A lower limit of detection for zinc bacitracin (3 mg/kg) is achievable (see Table 2), but should be
established with an in house validation first.
