Davison said that some poultry producers have eradicated SE by heating empty chicken houses with grain dryers.

Of 30 broiler houses cultured for SE after cleaning, records con cluded that dry cleaning with a complete wash down works best to eradicate SE. Dry cleaning and the use of formaldehyde was second best Rodent Control Dr. Maxcy Nolan of the Univer sity of Georgia said that it isn’t unusual to find 500 or more rats in a poultry operation. He pointed out several ways that producers can locate, identify, and erradicate rodent problems. Because rats sel dom travel more than IS feet from homebase, they can be tracked by locadng their droppings and by noticing tracks left in dust or in flour sprinkled over an area. By focusing on specific areas, rodents can be more quickly eradicated. “Rodents,” he said, “would rather live in walls than any other place. They also would rather eat chicken feed than bait. To eradi cate them, you must know where to put bait and switch compound.” Cleaning, Disinfecting Dr. Sherrill Davison of the Uni versity of Pennsylvania reported on the disinfectants that are avail able on the market.
