Is it possible to obtain SEM images of stainless steel surfaces used in the manufacture of foods?
Such surfaces get into contact with a variety of food ingredients and unless they are frequently cleaned, they could become sources of food-borne pathogens. Could scratches in smooth surfaces provide hiding places for some hardened microorganisms? Although it is not possible to place large subjects into electron microscopes, it is possible to replicate surfaces of interest and examine the replicas of small surface areas. A replication procedure now added to these Web sites makes it possible to show the details of steel surfaces including bacterial contamination. Does cryofixation of hydrated foods produce more accurate images of their structures than chemical fixation? It may, under certain conditions, which, however, are not easy to meet. Otherwise the structure of the sample may be distorted by the development of ice crystals. Several food microscopists have lately asked for advice on the fixation of fat for transmission electron microscopy. Although osmium tetroxide reacts with unsa
