“It’s a chain reaction, creating a dynamic and ongoing response that is even more overpowering than antibiotics,” Didar says. “No other antibacterial product – not even bleach – has the special properties that phages do.”Another major advantage of using phages in agriculture and food production is that they can be directed very specifically to take out harmful strains of bacteria without killing beneficial bacteria that enhance foods’ taste, smell, and texture.
