Sanitizing in food production environments is essential to prevent, reduce, and/or eliminate foodborne pathogens. Biofilms consist of one or more different types of microorganisms and can grow on numerous types of surfaces (Costerton,1999). SLRs provide transparency about what steps were taken to acquire the sources included in the analysis (Liberati et al.,2009; Moher et al., 2009). The references obtained from the databases were based on specific eligibility criteria to ensure reproducible results. The inclusion criteria included six surface types (stainless steel, glass, plastic, polyurethane, PVC, rubber), seven sanitizer types (anionic acid, benzalkonium chloride, iodine, iodophor, peracetic acid, quaternary ammonium, and sodium hypochlorite), three bacteria types (L. monocytogenes, Salmonella spp., and Shiga toxin-producing E. coli), biofilm methodology (including time, temperature, and media), starting concentration and ending concentration or log reductions present, units in log CFU/cm2, stating whether the biofilm was single species or multi species, sanitizer concentration, sanitizer contact time, temperature of sanitizer application, neutralizer used, and biofilm preparation. The outcomes from this SLR will help fill knowledge gaps for future biofilm research and improve biofilm removal with chemical sanitizers. Overall, this study brought to light many future topics of research as well as issues with biofilm removal that can be improved from past research.
