    The 5-minute test ßeta-s.t.a.r. Combo (Neogen Corporation, Lansing, MI) was validated at ILVO-T&V according to Commission Decision 2002/657/EC and the CRL Guidelines for the validation of screening methods by determination of the test specificity, detection capabilities and test robustness.
    In the validation study the test showed to be very specific as a real interference was only caused by clavulanic acid at 700 µg/kg and above. The ßeta-s.t.a.r. Combo detects all ß-lactams and tetracyclines with a MRL in milk at their respective MRL except for cefalexin and desfuroylceftiofur.
    Positive results for milk with an abnormal composition/quality should be considered with caution since interferences (false positive results) were observed. Retesting of initially positive milk samples could be a recommendation.
