DSM Food Specialties has announced the successful validation of its testing tool, Delvotest T, 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.

Delvotest T is a broad-spectrum test that identifies a variety of antibiotics, with particularly high sensitivity for tetracyclines. 

Margarida Branco, product line manager tests, told DairyReporter the testing is very simple and quick to administer.

“For dairies, Delvotest T minimizes costs associated with contaminated milk, such as disruption of production, disposal and additional testing. Our test is easy to use (no specialized analyst required) and cost-effective (no sample preparation). The most recent external validation carried out by Taylor & Francis further confirmed that fact,” Branco said.

AFNOR certified test

She added that it gives results in about three hours.

Branco added that the test, “is widely recognized as the most reliable and accurate and is considered the gold standard in antibiotic residue testing in most European countries. Furthermore Delvotest T is the only AFNOR (Association Française de Normalisation) certified broad spectrum test.”

The testing tool is utilized around the world, Branco noted.

“It is implemented as the national reference test by the majority of national laboratories in Europe, in countries such as France and the Netherlands,” she told DR.

“Delvotest T is globally used by farmers, dairies and Milk Control Laboratories and recognized for its consistency, reliability, accuracy and performance by both customers and independent authorities.”   

Ingrid Damen, business line manager food & crop protection, at DSM Food Specialties, said: “The presence of antibiotic residues in raw milk pose a significant risk to consumer health, including allergic reactions and antibiotic resistance. It is therefore vital that farmers, dairies and milk control laboratories take specific measures to determine the quality and safety of their milk.”
