'The Food and Drug Administration has approved
a mixture of viruses as a food additive to protect people. The additive can
be used in processing plants for spraying onto ready-to-eat meat and poultry
products to protect consumers from the potentially life-threatening bacterium Listeria
monocytogenes (L. monocytogenes).
The viruses
used in the additive are known as bacteriophages. Bacteriophage means "bacteria
eater." A bacteriophage, also called a phage (pronounced fayj), is any
virus that infects bacteria.'
