Review recommends using a combination of technologies to reduce the spread of bacteriophages in yogurt and cheese products
Bacteriophages (phage) are airborne viruses that kill starter cultures, resulting in failed batches of cheese or poor-quality dairy products but do not affect humans. Phages tolerate extreme heat and survive up to one year in dry powders that later may be incorporated into fermented products like yogurt. Researchers from the University of Hohenheim in Stuttgart, Germany, say the best methods for removing dairy bacteriophages from fluid whey are to combine moderate heat (<70 C) with either membrane filtration or ultraviolet (UV) irradiation.
