Aflatoxin M1 is the in vivo metabolite of aflatoxins, which is known to be the most carcinogenic substance ever. It always appears in milk secreted by cow which intake the contaminated feed. For kids or babies whose main food is milk, especially milk powder from dairy industry, the potential risk is quite serious. Thus very low maximum residue limit is set the aflatoxin M1 in milk and in other dairy products. In European Union, the MRL of aflatoxin M1 is 50ppt, that is 50micrograms per liter, while in USA and China, it is set to 500ppt, which is 500micrograms per liter.
The conventional methodologies to identify aflatoxin M1 in milk are ELISA, HPLC or IAC-HPLC or LC/MS/MS, which always take place in labs which are equipped with instrument like ELISA reader or HPLC or others, which are considered to be time-consuming or with high cost. For milk testing, especially for milk tank testing, it is vital to find a tool that identify the hazard on site and in time to avoid further damage and loss.
Ringbio Aflatoxin Test kit (Art. No.: 100004) is a rapid testing product to identify if aflatoxin M1 in milk is over the maximum residue limit of the European and USA regulations. It takes only 3-5min to get a direct result which requires no additional instrument. Lab staff or farm workers can easily operate the test even without any special trainings. The result is demonstrated by two lines on the test kit, which can be observed quite simply. By comparing the colors of control line and test line, the concentration of aflatoxin m1 in the test sample can be determined.
