Regulatory Info

Charm tests can help you lower operating costs and improve transportation efficiency by clearing good milk quickly. Charm’s patented ROSA technology targets drug sensitivities as close to regulatory levels as possible, preventing the unnecessary rejection of milk that can be caused by overly sensitive screening tests.

Charm’s ROSA portfolio includes tests for the detection of the most common antibiotics and aflatoxin M1. Charm ROSA strips are manufactured to test for US tolerance levels, EU MRL/CODEX, Canadian MRLs, multiple other country-specific requirements, and have been granted approval by regulatory authorities around the world.

Speed, ease of use, and minimal equipment requirements make ROSA tests incredibly versatile; they can be run by farmers, veterinarians, truck drivers, milk receiving, and milk testing laboratories.

Test results from ROSA strips can be read and officially recorded using the Charm EZ system or Charm EZ Lite system, or they can be interpreted visually in an unofficial capacity, making them ideal for farm use.
