Molds such as Aspergillus and Penicillium, produce ochratoxin A (OTA) in various foods such as grapes, grains, coffee beans, etc. Climates with more humidity, rainfall and hotter temperatures yield crops with higher amounts of OTA. Although, the EU does not have a maximum allowable OTA value for human milk and serum, Ochratoxin A has been shown to be teratogenic, nephrotoxinic, carcinogenic, and an immunosuppressive agent.(1) It has also been linked to Balkan endemic nephropathy which is a type of kidney disease that is common in the rural areas of Yugoslavia and Bulgaria.(1) Testing serum or human milk can be practical to evaluate internal ochratoxin exposure from eating habits.(2) It is suspected that humans have a widespread exposure to this toxin because of its long elimination half-life and widespread existence in human food and animal feed. From constant ingestion of foods contaminated with OTA, the toxins can build up in the body and can pass through the placenta to the fetus. It is suspected that a fetus could be more venerable to OTA's risk factors than adults.(1) OTA is also commonly found in human milk and could pose a serious threat to newborns.(3)

New ELISA Assay for Ochratoxin A
In response, at Helica Biosystems, Inc., we have developed a simple, user-friendly ELISA-based test. This simple, sensitive, and valuable ELISA is suitable for the quantitative measurement of ochratoxin A in human milk, serum and urine.
