It seems like anything — your insightful comments, cat pictures, video of your coworker falling over — can be instantly shared, then spread from one smartphone, connected mind to the next, like a super-contagious flu. There rarely seems to be any rhyme or reason to their spread.
In the analog world of dairy, we’ve long had struggles with a less entertaining viral spread, that of the dreaded phage. Bacteriophage (their name literally means “eater of bacteria”) are viruses that infect and kill the bacteria we as cultured dairy producers so loving tend to. I’ve heard stories of seasonal winds, cursed tanks, and even maintenance guys walking by at the wrong time, and before you know it, the phage have gone viral, and all that’s left is a ruined vat.
