COMET4 Dairy Testing Kit: Setting New Standards for Milk Safety in Australia

One Device. One Drop of Milk. Total Assurance.

Milk safety begins with precision testing — and COMET4 is redefining how Australian dairy producers detect antibiotic residues. As the first AOAC-approved automatic broad-spectrum antibiotic testing system, COMET4 offers unmatched accuracy and speed. Now available through Vendart Diagnostics, this advanced dairy testing kit in Australia helps producers, collectors, and laboratories stay compliant, confident, and always audit-ready.

Why Antibiotic Testing Matters

Antibiotic residues in milk pose a major threat to consumer safety and the entire dairy supply chain. Even trace amounts can lead to rejected batches, regulatory violations, and loss of trust. Under stringent standards such as the EU Maximum Residue Limits (MRLs) and FSANZ regulations, dairy processors must ensure milk is free from unauthorised antibiotic levels.

This is where COMET4 makes the difference — offering rapid, reliable, and fully automated detection of antibiotic residues in milk.

Why Choose COMET4

With the Eclipse Farm-4G microwells, COMET4 allows operators to test up to four milk samples simultaneously. Each test result is automatically analysed, digitised, and sent to the COMET4 mobile app and test4all cloud platform, ensuring secure data storage and seamless traceability.

It’s not just a testing device — it’s a complete digital solution for modern dairy safety management. Whether you’re in the field, at a collection centre, or in a lab, COMET4 delivers accuracy, assurance, and traceability anytime, anywhere.

The Science Behind the Simplicity

COMET4 works on a growth inhibition assay using Geobacillus stearothermophilus. The process is simple:

Add one drop of milk to the pre-filled test tube.

If no antibiotic residues are present, bacterial growth changes the medium’s colour from blue to yellow.

If antibiotics are present, the colour remains blue, indicating contamination.

The COMET4 incubator reader interprets this colour change, converts it into a numerical result, and sends it automatically via Wi-Fi, Bluetooth, or 4G.
