β-lactam 3-Min. Test (MRLBL3) – Beta Lactam Test

In just 3 minutes, the Charm MRLBL3 Beta-lactam Test can detect the presence of 13 primary beta-lactam drugs in milk at or below EU and CODEX maximum residue limits. Lower operating costs and improve transportation efficiency by clearing good milk quickly with the Charm ROSA (Rapid One Step Assay) lateral flow strips which detect aflatoxin M1 and the most common antibiotics used to treat dairy cows. ROSA tests use patented technology to target drug sensitivities to safe and regulated levels, which prevents unnecessary rejection of milk caused by overly sensitive screening tests.

The tests are easy to perform and are manufactured to test for US Safe Levels, EU MRL/ CODEX/ Customs Union maximum residue limits and multiple other country-specific requirements. Charm ROSA tests have been granted approval by regulatory authorities around the world. The MRLBL3 is run by farmers, veterinarians, truck drivers, milk receiving, and milk testing laboratories because of its ease of use, portability, and minimal equipment requirements.

Approvals/Validations: Validated by Institute for Agricultural and Fisheries Research (ILVO-T&V, Belgium)
