Are any disinfectants effective in the presence of organic matter such as manure?
Most commonly used disinfectants do not work well in the presence of organic matter. Most disinfectants work only on a relatively clean surface. Boots, for instance, should be thoroughly cleaned before disinfection. Yards where poultry are kept can be allowed time to dry so that sunlight can act as a disinfectant. Only harsh chemicals can disinfect dirt or manure, and these should be used with extreme caution by qualified individuals.
