Dr. Gisele Ravagnani joins Lanxess Tech Talks to unpack thescience behind effective barn disinfection—how chemistry, contact time, temperature, organic load, and surface prep drive kill rates. We get practical on entries and boot dips, trailer/load-out protocols, biofilm control, winter performance, and the most common mistakes that waste product and time. Clear, barn-level checklists you can use tomorrow to tighten biosecurity and protect herd health.
