I don't understand what the debris component is.

The effectiveness of bird feeder cleaning methods with and without debris

Lisa M. Feliciano,1 Todd J. Underwood,1* and Daniel F. Aruscavage1

ABSTRACT-Although feeders provide supplementary food to wild birds, they can be 
a site of disease transmission. Periodic cleaning of bird feeders is 
recommended to prevent disease transmission, but little is known about which 
cleaning methods are most effective. We determined the effectiveness of 3 
cleaning methods (scrubbing with soap and water, bleach soak, and scrubbing 
with soap and water followed by a bleach soak) in removing Salmonella from 
feeders with debris from normal field use and without debris. Feeders were 
inoculated with Salmonella enterica in the lab and then swabbed before and 
after cleaning to determine the percent reduction of Salmonella colony forming 
units (CFU/mL). All cleaning methods effectively reduced levels of Salmonella 
on feeders without debris, but the presence of debris significantly lowered the 
percent log reduction of Salmonella CFU/mL on feeders. The bleach soak and the 
scrubbing with soap and water plus bleach soak methods had a significantly 
higher percent reduction in Salmonella CFU/mL than the scrubbing with soap and 
water method overall. A significant interaction between debris and cleaning 
method was noted, however, indicating that the presence of debris greatly 
lowered the percent reduction of Salmonella CFU/mL on feeders cleaned with the 
scrubbing with soap and water method compared to other methods. Overall, we 
recommend either scrubbing with soap and water or a bleach soak to clean 
feeders with minimal debris, but suggest a combination of these 2 cleaning 
methods if feeders have heavy debris or if diseased birds are known to be in 
the area.
