It is important that livestock trailers, maternity and calf pens and other areas suspect of being contaminated with Salmonella be properly cleaned before the disinfectant is applied. If these areas are not properly cleaned, the disinfection step is much less effective at killing pathogens. High-pressure washing should not be used because of the risk of cross-contamination of the environment and aerosalization of contaminated material, which can cause human and animal infection. Importantly, livestock owners and managers should understand that while high-pressure washers do remove gross soils, such as dried fecal material, it does not consistently remove bacterial biofilms. Biofilm removal is an essential and vital component of proper cleaning. The following is a simple cleaning and disinfection protocol that is widely used in livestock operations in the United States.
