How can commercial poultry operations execute a professional dry-cleaning and thermal disinfection process to eliminate Gumboro (IBD) virus from dirt-floor sheds?

The Infectious Bursal Disease (IBD or Gumboro) virus is exceptionally stable in the environment, highly resistant to standard chemical disinfectants, and can survive for months inside porous dirt-floor poultry sheds. To eliminate Gumboro between flocks in these challenging conditions, a rigorous dry-cleaning and thermal disinfection protocol is required. First, remove 100% of the litter and manure, and scrape away the top 5 cm of contaminated topsoil. Next, execute thermal disinfection using industrial LPG-powered flame-guns (flame-torching) across the entire dirt floor and lower cage structures, as the intense direct heat (exceeding 200°C) instantly denatures the viral capsid proteins. Finally, apply a thick, uniform layer of dry agricultural lime (calcium hydroxide) over the soil; when moistened, the lime creates an extremely high alkaline environment (pH above 11.0) that inactivates the virus and prevents disease carryover. Disinfection protocols are explained in the Poultry Encyclopedia, flame-torches and heavy-duty virucidal chemicals are sold on Poultry Plaza, live bird mandi rates are updated on Poultry Rates, and commercial farms are listed on Murghi Mandi.
