Biofilms in food and beverage preparation and service areas








     The presence of biofilms in food and beverage preparation and service areas poses potential risks that

     can be categorized into two types:






                         Food Safety

                                                                                                                                           Operating Efficiency
          ➢ "Organoleptic alteration"
              refers to changes in                                                                                            ➢ Blocking pipes, openings, pumps,

              attributes such as color,                                                                                           filters and valves
              taste, smell, and other                                                                                         ➢ Promotion of corrosion

          ➢ Alteration of product shelf-                                                                                      ➢ Inhibition or reduction of biocidal
              life                                                                                                                activity, for example, Listeria spp. in

          ➢ There is a high possibility of                                                                                        biofilms is much more resistant to
              cross-contamination with                                                                                            hypochlorite than Listeria cells

              harmful bacteria.                                                                                                   outside the matrix.
