A range of products are commercially available for disinfection of low-moisture food production
areas. Isopropanol has the added benefit of evaporating quickly and 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.
