Charm Sciences has announced the release of the Charm Sulfa Test for raw commingled cow milk.
This lateral flow strip test can detect all members of the sulfonamide range of drugs in milk.
Charm Sulfa Test detection levels meet or exceed the US Food and Drug Administration's (FDA's) Safe Level and the Canadian MRL of 10ppb for most sulfa drugs.
The FDA has banned the use of certain sulfa drugs such as sulfamethazine in animals because they are known secondary carcinogens in mice.
Using a simple dilution procedure, the Charm Sulfa Test detection level may be adjusted to meet the European Union's MRL of 100ppb total sulfa drugs.
'By enabling multiple sulfonamides to be detected with a simple all-in-one test, Charm customers gain the added security of knowing that they will pick up any member of the sulfonamide family,' said Meikel Brewster, vice-president of sales at Charm Sciences.
The Charm Sulfa Test uses the company's patented Rapid One Step Assay (Rosa) technology, combining fast, accurate detection with ease of use.
Users simply add milk to the test strip, incubate for eight minutes and read on the Rosa Reader.
The Rosa Reader stores results electronically for data capture, record keeping and reporting.
The Charm Sulfa Test joins the Charm range of Rosa milk tests.
Other Rosa milk tests detect beta-lactams, tetracyclines, enrofloxicin, chloramphenicol and aflatoxin M1.
Combination beta-lactam/tetracycline kits are also available.
Charm produces separate test kits to meet US, European and other regulatory requirements.
All Rosa tests can use the same incubator and reader.
