AAEP BIOSECURITY GUIDELINES


1. Remove all buckets, hay nets, feed tubs, stall webbings, metal grates, etc. and scrub with detergent solution, rinse, disinfect and then rinse thoroughly with potable water and allow to dry.


2. For stalls with non-porous walls and floors (ideal situation): a. Wet down all surfaces -- walls, ceilings, ledges (top of walls) -- with detergent and water. Powdered laundry detergent can be used; some veterinary disinfectants also have a detergent incorporated in the mix.


b. Allow 5-10 minutes for the liquid to soften caked-on organic material then scrub surfaces with a stiff- bristled broom to loosen all material.


c. Rinse, beginning at the top of walls and from walls towards the drain. Repeat until surfaces are clean, including corners, ledges and drains. NOTE: Do not use power washers set at >120 psi which can aerosolize pathogens. A garden hose with a regular nozzle can be used.


d. Squeegee excess water off surfaces, or allow them to dry.


e. Apply disinfectant prepared according to label directions on surfaces, starting at the top of stall walls and working from the far end of the stall to the exit. Allow to dry.


f. Repeat disinfection step if suspect or confirmed difficult organisms are found or suspected. Bacteria such as Salmonella and certain viruses such as rotavirus are generally difficult to inactivate. Herpes and influenza viruses are more susceptible to detergents and disinfectant and one application of detergent and disinfectant should be sufficient.


3. If stalls are constructed of porous materials (wood construction, dirt or clay flooring, etc), it must be recognized that these are extremely difficult to clean and disinfect. a. Remove all bedding and organic matter and thoroughly dry scrub all surfaces water to remove as much organic matter as possible.


b. Follow up with scrubbing stall walls with a detergent solution. Cleaning with large quantities of water can turn dirt or sand floors into a slurry and should be avoided.


c. Disinfectants can be sprayed on surfaces but may have inadequate results, and persistence will depend upon the involved organism. Sunlight exposure may be helpful for inactivation of potential pathogens (Weese et al, Survival of Streptococcus
