A range of products are commercially available for disinfection of low-moisture food production
areas. Isopropanol has the added benefit of evaporating quicklyand leaving no residue on food production surfaces. The objective of this research was to evaluate the efficacy of a model cleaning and sanitation method involving 60% isopropanol with and without the addition of quaternary ammonium compounds on Salmonella removal from pilot-scale peanut butter processing equipment.
