Bovine mastitis is more common than other diseases and accounts for about 30% of all dairy cow injuries. The treatment of bovine mastitis is with antibiotics, but once administered, they remain in the body for a certain period of time, during which time the shipment of raw milk is severely restricted, making a safe treatment method a challenge for dairy farmers.

Aureobasidium (black yeast) culture is a food product and is safe, yet it has been used to prevent mastitis and to improve symptoms and treatment of affected cows.
