Europe: DSM’s tool validated for dairy antibiotic residue testing

DSM Food Specialties’ testing tool, Delvotest T, has been validated for determining up to 27 antibiotic residues in raw cow’s milk and dairy ingredients, such as milk powders.

The report, published by Taylor & Francis, reviews the test’s ability to identify multiple antibiotic residues.

Validation was performed by two independent facilities in Europe and Asia in accordance with the European Community Reference Laboratories (CRL) guidelines.

The tool is a broad-spectrum test which identifies a variety of antibiotics at EU maximum residue levels, with particularly high sensitivity for tetracyclines.

In the validation study, Delvotest T was evaluated against five criteria, including the screening target concentration (STC) detection capability, false-positive (FP) and false-negative (FN) rates, robustness and cross-reactivity.

The report states that “this multi-residue test was easy to use (no specialized analyst required), cost effective (no sample preparation), fast in terms of result delivery (3hrs 15mins) and robust since incubation temperature change and delay of reading did not impact the final result.”

“The presence of antibiotic residues in raw milk pose a significant risk to consumer health, including allergic reactions and antibiotic resistance,” Ingrid Damen, business line manager food and crop protection.

“It is therefore vital that farmers, dairies and milk control laboratories take specific measures to determine the quality and safety of their milk.”
