Ochratoxin A (OTA) is a toxic secondary metabolite produced by some Aspergillus and Penicillium species and is widely present in grains (such as cereals), spices, dried fruit, and coffee beans. Ochratoxin A can be accumulated in the meat of animals, and therefore can be found in meat and meat products. It possesses acute liver and kidney toxicity, is a teratogen, mutagen, and carcinogen, and poses serious health risks to human. TriboTM ochratoxin A rapid test strip provides a rapid and convenient test for OTA with a colloidal gold immunochromatographic design. It provides a fast (results shown in 10 minutes), simple (no instrument is required, and results can be observed visually), sensitive and reliable detection approach for the presence of ochratoxin A in grains and grain products, spices, and coffee beans. The lower limit of detection (LOD) of ochratoxin A in the sample is 2 ng/ml (2 ppb).
