I don't understand what the debris component is. ________________________________ From: bounce-124015218-48869...@list.cornell.edu <bounce-124015218-48869...@list.cornell.edu> on behalf of Alicia <t...@ottcmail.com> Sent: Sunday, October 13, 2019 4:20 PM To: cayugabirds-l Subject: [cayugabirds-l] Fwd: cleaning bird feeders
This was on a different bird list, thought it might be of interest to Cayuga birders. -------- Forwarded Message -------- The Wilson Journal of Ornithology 130(1):313-320, 2018 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. -- Cayugabirds-L List Info: Welcome and Basics<http://www.northeastbirding.com/CayugabirdsWELCOME> Rules and Information<http://www.northeastbirding.com/CayugabirdsRULES> Subscribe, Configuration and Leave<http://www.northeastbirding.com/CayugabirdsSubscribeConfigurationLeave.htm> Archives: The Mail Archive<http://www.mail-archive.com/cayugabirds-l@cornell.edu/maillist.html> Surfbirds<http://www.surfbirds.com/birdingmail/Group/Cayugabirds> BirdingOnThe.Net<http://birdingonthe.net/mailinglists/CAYU.html> Please submit your observations to eBird<http://ebird.org/content/ebird/>! -- -- Cayugabirds-L List Info: http://www.NortheastBirding.com/CayugabirdsWELCOME http://www.NortheastBirding.com/CayugabirdsRULES http://www.NortheastBirding.com/CayugabirdsSubscribeConfigurationLeave.htm ARCHIVES: 1) http://www.mail-archive.com/cayugabirds-l@cornell.edu/maillist.html 2) http://www.surfbirds.com/birdingmail/Group/Cayugabirds 3) http://birdingonthe.net/mailinglists/CAYU.html Please submit your observations to eBird: http://ebird.org/content/ebird/ --
