Control of bacteriophage in cheese factories


, : Control of bacteriophage in cheese factories. Seravac Annual Cheesemakers Symposium 1985: 112-119

Factory design and air-flow requirements that would minimize the spread of phage in cheese factories, and routine control measures to combat phage development during starter preparation and cheesemaking, are outlined.

Severe outbreaks of " slowness " caused by infection of the cheese starter with bacteriophage in two cheese factories were overcome in 1943. In 1944 the factory staffs achieved "virtually complete freedom from bacteriophage attacks...
