GrainPro Aflatoxin Test Kits provide an affordable testing solution for use in the field or reasonably-equipped laboratories where aflatoxin levels can be accurately determined in just a few minutes. The Screen test is suitable for use on many types of grains and will give a qualitative visual result: whether the sample exceeds a 5, 10 or 20 ppb (parts per billion) contamination level. Screen tests do not give numerical values of afla level.
What are Aflatoxins? Aflatoxins are produced by the molds Aspergillus flavus and Aspergillus parasiticus, and are commonly found in agricultural commodities worldwide. Aflatoxins are common in grains such as corn and in nuts such as peanuts. They may also be found in spices such as red chilli peppers. Aflatoxins have potent carcinogenic effects in animals and humans. There is a scientifically proven link between liver cancer and prolonged intake of aflatoxin-contaminated food. Aflatoxin affects the liver, and suppresses proper functioning of the immune system, which has been found to be a facilitator of several diseases, including cancer and HIV.
Aflatoxin Occurrence and Levels The occurrence of aflatoxins is related to poor harvesting, drying and storage practice. It is hard to detect, since it is invisible and has no smell or color. Agricultural commodities suspected of having aflatoxin should be tested on its occurrence. Acceptable aflatoxin levels for contaminated grains vary from country to country. The average acceptable level for humans is in the 5-10 ppb range. For animals, depending on size, the limit is 20 ppb or higher.
Testing Practices Because aflatoxins do not occur uniformly through the entire lot of grain and may be localized in a small area, the best testing approach is to make a composite sample consisting of subsamples from every part of load, bin, or unit. Alternatively, the recommended procedure is to sample periodically from a moving stream, combining these samples to obtain a composite sample.
