DELVOTEST T Official Antibiotic Residue Test in the Netherlands

DSM Food Specialties’ Delvotest® T was chosen by QLIP, Dutch partner in quality assurance in the agrofood chain, as the national reference test to detect antibiotic residues in milk. The broad spectrum test was selected because of its high sensitivity and reliability. The test is fully compliant with Dutch dairy regulations, promoting a high quality milk supply throughout the whole dairy chain, from farmer to dairy to consumer.


QLIP is commissioned by Dutch dairy companies to determine the composition and quality of farm milk samples. The analyses they perform meet the specific requirements of the official Dutch dairy regulations and detect the most relevant residues at or below the European Maximum Residue Levels (MRLs).

Delvotest® T is a broad spectrum test which identifies a variety of antibiotics at or below EU MRLs with higher sensitivity for tetracyclines than any other microbiological screening test. QLIP selected Delvotest® T because the test is closest to the aimed detection level and because of its robust performance and consistent results.

“In our search to improve antibiotic residue testing, Delvotest® T performed to our expectations”, according to Louw Beerstra, Head of the QLIP Routine Laboratory. “Last year, in July, we started using Delvotest® T as a screening test for antibiotic residues in milk. The test has a high sensitivity on tetracyclines, an antibiotic which is increasingly becoming a concern for many health authorities worldwide. In the Netherlands, there is a successful program in place to reduce the usage of antibiotics in general. A test like Delvotest® T is an important tool to safeguard the suitability of milk that forms the basis for the broad range of excellent quality Dutch dairy products.”

Through the implementation of Delvotest® T by QLIP, it has become the industry benchmark in the Netherlands to detect antibiotic residues in milk in the whole dairy chain.

MicroSnap Total- Same Shift Results – AOAC-RI Certified

Hygiena, a global leader in rapid food safety testing, has been awarded Performance Tested MethodsSM Validation (Certification Number 031501) from the AOAC Research Institute for MicroSnap™ Total, the first 7 hour total aerobic bacteria test. MicroSnap Total detects down to 1-10 organisms in 7 hours or less, which is at least 17 hours sooner than other AOAC-validated methods for the detection and enumeration of aerobic bacteria.

MicroSnap Total is a flexible test that may be used for product or environmental samples. Processors can now collect samples at the beginning of a typical 8-hour shift and get results within 7 hours to verify product quality or take corrective actions as necessary before the end of the day. Knowing results on both product and environmental samples by the end of the shift allows personnel responsible for food safety and quality to react to contamination in a timely manner, release held products sooner for extended shelf-life, and feel more confident about the quality and safety of the food being processed. The US Food and Drug Administration’s proposed rule for preventive controls in the Food Safety Modernization Act suggests a greater emphasis on environmental monitoring for food processors. Accordingly, MicroSnap Total meets the needs of food processors for a rapid, convenient, and affordable environmental microbiology screening test kit.

MicroSnap is a two-device test platform consisting of an enrichment device and detection device. The entire assay is run from start to finish in 7 hours with a 15 second read time. MicroSnap devices are measured with Hygiena’s EnSURE Monitoring System, a luminometer also capable of measuring adenosine triphosphate (ATP), Enterobacteriaceae, Coliform, E.coli, alkaline phosphatase (ALP), and acid phosphatase (ACP) tests. A video demonstration of MicroSnap Total may be found on Hygiena’sYouTube channel.

MicroSnap Total joins Hygiena’s AOAC-RI PTM validated tests for Coliform & E. coli. Other products from Hygiena include the world’s best-selling ATP monitoring systems and UltraSnap ATP test devices.

AOAC Research Institute is a division of AOAC International, a globally recognized, independent, not-for-profit association based in Gaithersburg, Maryland. Since 1992 the Research Institute has been striving to serve as a global provider of a complete range of products and services needed for the rapid validation and conformity assessment of commercial and analytical methods.
